Flyingfish or exocoetus is a fish.

The book 'Historia Generalis Plantarum' was written by John Ray.

One of the distinctive characteristics of most bacteria and other prokaryotes is a unique cell wall. The only bacterium that has no cell wall is mycoplasma.

It is an obligate aerobe.

 Acellular protists are both Plasmodium and Monocystis.

Whittaker (1969) gave the 'five kingdom classification' based on which he classified living organisms in five groups: Monera, Protista, Fungi, Plantae and Animalia.

 Hard covering of amoeba is known as cyst. It acts as a protective shield to overcome adverse circumstances.

Ammonifying bacteria release ammonia in the soil by decay and putrefaction. Nitrogen fixing bacteria can be symbiotic or non-symbiotic. Mycoderma aceti converts sugar solution to acetic acid.

Mycoplasmas are the organisms that completely lack cell wall. They are the smallest living cells known and can survive without oxygen.

They are unicellular, colonial or filamentous, marine or terrestrial algae. 

In starfish, locomotion is done by tube feet.

Sepia has an internal shell.

The ribosomes of prokaryotic cells are smaller than eukaryotic ribosomes. Prokaryotic ribosomes measure 70 S units.

In sporozoa, locomotory organ is absent.

Chlorellin is an antibacterial drug obtained from chlorella.

 The binomial name of French marigold is Tagetes patula. Itis a species in the daisy family (Asteraceae). It is native to Mexico and Guatemala with several naturalised populations in many other countries.

Malvaceae comes under polypetalae subclass. Polypetalae was defined as including plants with the petals free from the base or only slightly connected.

The scientific name of wheat is Triticum aestivum.

 All the florets are disc florets in vernonia.

 Hydra exhibits exogenous budding.

 Hydatid disease in man is caused mainly by infection by the larval stage of the dog tapeworm Echinococcus granulosus. Cyst formed in echinococcus is known as  hydatid cyst.

Sycon is a marine sponge. Sponges are marine invertebrates with a jelly-like mesohyl sandwiched between two layers of cells. 

Hydatid disease, caused by the parasite Echinococcus granulosus, mostly affects the liver and the lungs with hydatid cysts which consist of three layers: (1) the outer pericyst; (2) the middle laminated membrane; and (3) the inner germinal layer.

 Gemmules are internal buds found in sponges and are involved in asexual reproduction. It is an asexually reproduced mass of cells, that is capable of developing into a new organism i.e., an adult sponge.

Classical evolutionary taxonomy uses both evolutionary branching and divergence to classify organisms.

This is the correct order amongst which the species is the smallest and cohort is the largest taxon.

  InCanna flowers are asymmetrical.
