Vivipary means
-
Fruits are not formed.
-
Germination of seed on mother plant.
-
Formation of fruits directly by embryo.
-
Production of fruitless plant.
Vivipary is the condition, where the embryo grows first to break through the seed coat and then out of the fruit wall while still attached to the parent plant. This condition is found in Bruguiera, Ceriops, Kandelia and Rhizophora species.

Assertion is false but reason is true.
Claspers of cartilaginous fishes (sharks) is one pair between the pelvic fins. Claspers are analogous to penis of human male both act as copulatory organ and transfer the sperm into female.
Which of the following animals give birth to young ones?
-
Ornithorhynchus and Echidna
-
Macropus and Pteropus
-
Balaenoptera and Homo sapiens
-
Both (b) and (c)
An animal that is viviparous gives birth to young ones. The embryos are raised with special organs in the parents as they develop, those supply nutrients to the growing embryos. Example -Homo sapiens (humans), Macropus (Kangaroo), Pteropus (Flying fox), Camelus (Camel), Delphinus (Common dolphin), Balaenoptera (Blue whale).
Marsupials are
-
Viviparous
-
Oviparous
-
Ovo-viviparous
-
Omni-vorous
Marsupial mammals are viviparous mammals in which the embryo is born at a very early stage and complete its development outside the mother's body. Examples of living marsupials mammals are bandicoots, kangaroos, koalas etc.
Birds are oviparous.
-
True
-
False
- Oviparous animals are that lay eggs, with little or no other embryonic development within the mother. Birds are oviparous.
Which of the following is an egg laying mammal?
-
Panthera leo
-
Elephas maximus
-
Hemidactylus flaviviridis
-
Ornithorhynchus anatinus
-
Panthera leo which is commonly known as lion belongs to the family Felidae and comes under the class Mammalia (which give birth to their young ones).
-
Elephas maximus which is commonly known as Asiatic elephant belongs to the family Elephantidae and comes under the class Mammalia (which give birth to their young ones).
-
Hemidactylus flaviviridis is a species of lizards which is also known as the Geko or northern house gecko which belong to the class Amphibia.
-
Ornithorhynchus anatinus is also known as duck-billed platypus which is a semiaquatic egg-laying mammal.
-
So, the correct answer is 'Ornithorhynchus anatinus'.
In mammals egg are microlecithal and isolecithal because these are
-
Oviparous
-
Viviparous
-
Ovoviviparous
-
None of the above
Mammalian eggs have very little yolk (microlecithal) because the embryo obtains maternal nutritional support throughout its development.
How many moulting occur, from egg laying to the development of adult cockroach?
-
10 - 12 times
-
9 times
-
6 times
-
3 - 4 times
Each time the molting process is completed the cockroach will get bigger, change in color, and look more like an adult cockroach. The nymph stage of the cockroach life cycle can take anywhere from a month and a half to several years, depending on the environment, the type of cockroach, and the prevalence of cockroach disease and parasites. When the cockroach reaches its adult size it will not moult again. Many types of cockroaches will complete their transformation into adulthood with a pair of wings. Young adults may look almost exactly like a nymph, with the wings being the one characteristic that easily sets the two apart. The number of moultings in cockroach after hatching and development of a complete animal are more than 10 and they vary from one cockroach type to another.

Cockroaches are oviparous. The egg hatches at specific conditions to give birth to young ones. The eggs are carried by the mother cockroach around in a sac called an ootheca, which is attached to her abdomen. The number of eggs in each ootheca are about 16 and varies from species to species. Many female cockroaches drop or hide their ootheca shortly before the eggs are ready to hatch. Others continue to carry the hatching eggs and care for their young after they are born. But regardless of how long the mother and her eggs stay together the ootheca.
Cleidoic egg is an adaptation for
-
Aquatic life
-
Marine life
-
Terrestrial life
-
Aerial life
Cleidoic eggs are laid by terrestrial animals like reptiles and birds. The egg is surrounded by a hard porous shell. Gaseous diffusion occurs through porous shell. Egg of aquatic animals is covered by a jelly coat and not by a hard shell. The shell in cleidoic eggs protects the developing embryo and also makes available an aquatic environment for development. The yolk of an egg is a source of nutrition for developing an embryo.
Reptile and bird eggs are
-
Macrolecithal
-
Oligolecithal
-
Mesolecithal
-
Alecithal
Reptiles and birds are terrestrial animals. They lay large yolk-rich eggs which are covered with a porous shell. As the eggs are rich in yolk they can support the development of an embryo. Hence, embryogenesis occurs outside the body of the animal inside the egg. Such yolk-rich eggs are called as macrolecithal eggs.
Microlecithal eggs are found in
-
Reptilia and Aves
-
Amphibia, Aves and Reptilia
-
Reptilia, Aves and Chiroptera
-
Eutheria
Yolk is composed of
-
Carbohydrate
-
Protein
-
Phospholipid
-
All of the above
The yolk is a part of an egg, that feeds the developing embryo in animals. It is composed of carbohydrates (3.5%), protein (16%) and fats (phospholipids 26.5%) of total yolk. The main fatty acids present in the yolk is oleic acid, linoleic acid, palmitic acid etc.
Yolk is synthesized in
-
Liver
-
Fat bodies
-
Both A and B
-
Sertoli cells
The process of formation of the yolk is known as vitellogenesis. These are generally used to nourish the developing embryo in oviparous animals. They are deposited during oocyte maturation for use after fertilization and are synthesized in the liver or fat bodies as a common precursor termed vitellogenin.
Yolk cytoplasm contains
-
Ooplasm
-
Protoplasm
-
Deutoplasm
-
Trophoplasm
- Deutoplasm is the nutritive material present in the egg for development and nourishment of embryo. It is a non-living portion of the egg.
- Deutoplam is present in the yolk of eggs. Sometimes yolk and deutoplasm are used synonymously.

-
Amphibious
-
Oviparous
-
Triploblastic
-
Viviparous
Amphibious are the animals that can live on water as well as on land.
Oviparous are the animals that lay eggs.
Triploblastic describes the animal having a body composed of three embryonic cell layers as the ectoderm, mesoderm, and endoderm.

-
Hermaphrodite
Unisexual is where the organism is either male or female.
Oviparous animals are those that lay eggs, with little or no other embryonic development within the mother.
Viviparous are animals that give birth to live young ones.
Hermaphrodite is the one which has both male and female reproductive organs.
So, the correct answer is option B.
Which of the following animals are correctly categorised ?
Oviparous | Viviparous |
---|---|

Oviparous are the animals that lay eggs and the embryonic development majorly takes place outside the body of the mother. From the options, pigeon and crocodile lay eggs.
Viviparous are the animals that give birth to live young ones that have developed inside the body of the female parent, Of the given options, rat and horse are viviparous.
So, the correct answer is option C.
Egg laying animals are known as
-
Viviparous
-
Oviparous
-
Sterile
-
Hermaphrodite
Oviparous animals lay an egg and the embryonic development takes place outside the human body. Example birds.
While viviparous animals are those that give birth to live young ones. Example human beings.
So, the correct answer is option B.
The development of embryo inside an egg is called as
-
Vivipary
-
Carnivorous
-
Omnivorous
-
Ovipary
Vivipary is the development of the embryo inside the body of the mother, eventually leading to live birth.
Carnivorous are animals that feed on animal tissues.
Omnivorous are animals that feed on plant and animals.
Ovipary is the method of reproduction in which eggs are laid and embryos develop outside the mother's body, each egg eventually hatching into a young animal.
So, the correct answer is option D.
The animal that reproduces by laying eggs is
-
Cat
-
Dog
-
Cow
-
Fish
Fish lay eggs instead of giving birth to little fish. As the fish grow, they hatch into fry with an attached yolk sac and then mature into fish. The process usually takes around a week to 10 days, although it can vary widely. Cat, dog, and cow can not lay eggs.
Oviparous animals give birth to young ones.
-
True
-
False
- Oviparous organisms produce their offsprings by laying eggs. Their Egg contains an embryo.
- While viviparous organisms produce offspring by giving birth to young ones. They do not lay eggs.
Give the correct correlation
Oviparous : _______ :: viviparous : ______
-
Crow, cat

Crow, frog
Crow is oviparous. Cat is viviparous. Frog is oviparous. Lizard is oviparous. Dog and cow both are viviparous. Crow and frog both are oviparous.
So the correct option is Crow, Cat.
The correct option is A.
Animal which lay eggs are called _____
-
Vivparous
-
Oviparous
-
Both a and b
-
None of above
Oviparous animals can reproduce by laying eggs. This is how most fish, amphibians, reptiles, insects, and arachnids reproduce. All birds and monotremes also reproduce like this. But, viviparous animals are born as the live young individuals.
So the correct answer is oviparous.
The correct option is B.
Animal which give birth to the young ones are called _______.
-
Oviparous
-
Viviparous
-
Ovi-viviparous
-
None of these
Animals that gives birth to their young ones are called Viviparous.
Give example of viviparous animals.
-
Human beings
-
Frog
-
Butterfly
-
All of the above
In the viviparous type of animals, females can give birth to young ones. Mammals (except egg-laying mammals), like whale, shark, mouse, humans are examples of viviparous animals. Frog is an oviparous animal. The butterfly is an oviparous animal
So, the correct answer is Human being.
The correct option is A.
The animals in which complete embryo develops in the mother's body through placenta are
-
Oviparous
-
Viviparous
-
Ovo-viviparous
-
Herbivorous
- Oviparous animals are the animals that lay eggs.
- Viviparous animals give birth to the living offspring that develop within the mother's body (as in the case of most of the mammals).
- Ovo-viviparous give birth to the young ones in eggs which are hatched within the female body (as in some reptiles and fishes).
- Herbivorous animals are those that feed exclusively on vegetable food.
Foetus developing in the genital track without getting nourishment from the mother is a case of
-
Vivipary
-
Ovipary
-
Ovo-vivipary
-
None of the above
Ovipary is the development of foetus outside the mother's womb. Example, egg-laying birds.
Hens and frogs both are
-
Oviparous
-
Viviparous
-
Ovoviviparous
-
None of these
Oviparous animals are animals that lay eggs, with little or no other embryonic development within the mother. Hen and frogs, they both lay eggs and hence are oviparous.
On the other hand, viviparous are those that give birth to live young ones and in ovoviviparous, there is internal fertilization and young are born live but there is no placental connection and young ones are nourished by yolk egg.
So, the correct answer is option A.
Animals giving birth to young ones are
-
Viviparpous
-
Oviparous
-
Triploblastic
-
Coelomate
Viviparous animals are those animals which give birth to young ones. Birth of fully developed young ones is attributed to the presence of a highly developed placenta which helps the embryo to develop fully in mother's womb.
So, the correct option is 'Viviparous'.
In markets, eggs of birds are available but never eggs of dogs, because
-
Birds lays eggs but dogs do not
-
Bird's eggs are large but dog's eggs is very small
-
Bird's eggs are covered but dog's eggs are not
-
None of these
- Birds are oviparous meaning they lay eggs. On the other hand, dogs do not lay eggs and are viviparous meaning dogs give birth to live young ones. So, bird's eggs are available in markets.
The eggs of fish are covered by
-
Jelly like membrane
-
Hard shell
-
Both A and B
-
None of these
The egg of fish is surrounded by a jelly-like membrane but does not develop a hard shell. Some fishes lay an egg that is covered by a hard leathery coat.
The eggs of frogs do not have shells for protection, yet they are safe in water. How?
-
They are covered and embedded in a jelly like strip
-
They are covered with bark
-
They are covered with yolk
-
Both A and B
- The female frog covers the eggs with a jelly-like substance that causes the eggs to float to the water's surface and also protects from any damage.
Offsprings of oviparous animals are at greater risk of survival as compared to those of viviparous animals because
-
Proper embryonic care and protection is absent
-
Embryo does not develop completely
-
Progenies are of smaller size
-
Genetic variations do not occur
Select the option which shows viviparous animals only.
-
Lizard, Turtle
-
Platypus, Crocodile
-
Cow, Crocodile
-
Whale, Mouse
Statement $1$: Viviparous animals give better protection to their offspring.
Statement $2$: In viviparous animals, young ones, after attaining a certain state of growth, are delivered out of the body of the female organism.
-
Both statements $1$ and $2$ are correct
-
Statement $1$ is correct but statement $2$ is incorrect
-
Statement $1$ is incorrect but statement $2$ is correct
-
Both statements $1$ and $2$ are incorrect
In oviparous animals such as reptiles and birds, fertilised eggs are covered by hard calcareous shell and are laid in a safe place. After incubation period, young ones hatch out. In viviparous animals such as majority of mammals including human beings, the zygote develops into a young one inside the body of the female individual. After a certain growth, young ones are delivered by the female individual. Due to proper care and protection, the chances of survival of young ones are more in viviparous individuals.
In these animals, the female retain the eggs inside the body after fertilisation and allows the development of embryo inside the body without providing extra nourishment to the developing embryo as the placenta is absent. Such animals are called as
-
Oviparous animals
-
Viviparous animals
-
Ovoviviparous animals
-
None of the above
Which one of the following is oviparous?
-
Platypus
-
Flying fox (Bat)
-
Elephant
-
Whale
Platypus, bat, elephant and whale, all belong to. Class Mammalia of sub-phylum Vertebrata. Out of the four, only platypus is oviparous (egg laying), rest are viviparous (glib birth to young ones).
Those who give birth to young-ones are called viviparous. Some flabes lay eggs. Therefore,
-
Some frogs do lay eggs
-
Some frogs are fishes
-
Some fishes do not lay eggs
-
Some fishes are oviparous
Giving birth to live young is called vivipary. When a species lay eggs it is called oviparity.
Egg with peripheral cytoplasm around the yolk is
-
Isolecithal
-
Microlecithal
-
Telolecithal
-
Centrolecithal
Centrolecithal eggs have yolk concentrated in the center as in insects.
Salamandra atra is
-
Ovoviviparous
-
Oviparous
-
Sexually sterile
-
Parthenogenetic
Ovoviviparous is the method of reproduction in which animals produce eggs, but instead of laying the eggs, the eggs develop within the mother's body. The eggs hatch within the mother. After hatching, they remain inside the mother for a time and are nourished there.
The process by way of which a larva or miniature adult comes out of the egg membranes is known as
-
Hatching
-
Emboly
-
Epiboly
-
Ingression
Larva comes out from the egg membranes is called as Hatching. Formation of a gastrula from a blastula by invagination is called as Emboly. cell movements that occur in the Gastrulation stage of embryonic development of some organisms are called as Epiboly and changes in the location or relative position of cells that takes place during the gastrulation stage of animal development is called as Ingression.
Organisms which give birth to young ones directly are
-
Oviparous
-
Ovoviparous
-
Viviparous
-
Both A and B
Option C viviparous
A hatching egg of chick is covered by plaster of paris. It is harmful for
-
Mother
-
Respiration
-
Excretion
-
None of the above
Egg of the chick is porous, which allows the exchange of oxygen and carbon dioxide between the inside of the egg and the environment. If it is covered by plaster of paris, then pores will be closed which can lead to several respiratory problems.
So, the correct answer is option B.
