  2. Algae 

  3. Protozoa

  4. All of the above

Show answer
Correct Option: A
Explanation:

Fungi are the multicellular eukaryotic organisms. The kingdom Fungi has only heterotrophic organisms.

A. Fungi are heterotrophic.
B. Algae come under kingdom Plantae and they are mostly autotrophic.
C. Protozoa come under kingdom Protista which has unicellular organisms that are both autotrophic and heterotrophic.
Hence, the correct answer is 'Fungi'.

  1. Bryophytes, pteridophytes, angiosperms, gymnosperms

  2. Angiosperms, gymnosperms

  3. Bryophytes, pteridophytes

  4. Gymnosperms, pteridophytes

Show answer
Correct Option: A
Explanation:

The Kingdom Plantae is also called as kingdom Metaphyta. The kingdom Plantae includes all types of eukaryotic, multicellular, photosynthetic plants found in this biosphere.

It includes bryophytes, pteridophytes, angiosperms, and gymnosperms.
This kingdom includes all types of plants like herbs, shrubs, trees, creepers, climbers, aquatic plants, desert plants, mountain plants, flowering, and nonflowering plants, etc.

Which of the following statements is correct about the kingdom Plantae?

biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

  1. They are multicellular eukaryotes

  2. They are usually autotrophic

  3. Their cells have cell wall, made up of cellulose

  4. All of the above

Show answer
Correct Option: D
Explanation:

The kingdom Plantae includes all plants i.e., trees, grasses, ferns and mosses, They are multicellular eukaryotes. They have nucleated cells. They have cell organelles like mitochondria and chloroplast. They contain chlorophyll and are capable of making their own food in presence of sunlight. So, they are called autotrophs. Their cells have distinct cellulose wall that other organisms lack. 

So, the correct answer is option D.

Most primitive member in which roots are not present is ____________.

  1. Psilotum

  2. Rhynia

  3. Lycopodium

  4. Selaginella

Show answer
Correct Option: B
Explanation:
Rhynia is a single-species genus of Devonian vascular plants. Rhynia is more primitive than Psilotum and both lack true roots. 
So, correct answer is Rhynia.

Algae can be described as

biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

  1. Autotrophic and chemosynthetic

  2. Autotrophic and photosynthetic

  3. Heterotrophic and photosynthetic

  4. Heterotrophic and chemosynthetic

Show answer
Correct Option: B
Explanation:

Algae is the group of organisms which is comprised of the unicellular and the multicellular organisms. These organisms possess the chlorophyll pigments which help in the trapping of the solar energy. The plants can perform photosynthesis and prepare their own food. The plants are autotrophic and have the ability to produce their own food.

So, the correct answer is 'Autotrophic and photosynthetic'

  1. Amoeba

  2. Paramoecium

  3. Green plants

  4. Bacteria

Show answer
Correct Option: C
Explanation:

  • Euglena is an example of an organism belonging to the kingdom Protista. All green plants are included in the kingdom Plantae.

Therefore, the correct answer is option C.

Kingdom plantae include which of the following sub-kingdoms?

biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

  1. Cryptogams and phanerogams

  2. Cryptogams and Porifera

  3. Thallophyta and Bryophyta

  4. Pteridophyta and Thallophyta

Show answer
Correct Option: A
Explanation:

Cryptogams and phanerogams are the two sub-kingdoms of kingdom plantae.
Porifera is phylum of kingdom Animalia. Thallophyta, Bryophyta and Pteridophyta are the division of kingdom plantae.

Thus option A is correct.

Kingdom Plantae includes organisms that are

  1. Unicellular and eukaryotic

  2. Multicellular, eukaryotic and saprophytic

  3. Multicellular, eukaryotic and autotrophic

  4. Multicellular, eukaryotic and heterotrophic

Show answer
Correct Option: C
Explanation:

Kingdom Plantae includes all multicellular eukaryotic organisms containing chlorophyll. They are autotrophs as they can make their own food with the help of solar energy. The cell wall of plants comprises of cellulose. They have the ability to grow by cell division. They lack motility. Thus, the correct option is C.
