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

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

  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
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

Algae can be described as

  1. Autotrophic and chemosynthetic

  2. Autotrophic and photosynthetic

  3. Heterotrophic and photosynthetic

  4. Heterotrophic and chemosynthetic
Reveal answer Fill a bubble to check yourself
B Correct answer
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'

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

Which of the following statements about the distinction between plants and animals is false?

  1. Plants have cell wall made up of cellulose.

  2. Plants have intermediate larval stages.

  3. Plants are extensively branched.

  4. Animals are heterotrophic.

  5. All of the above.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plants and animals though both livings are different in many ways. On considering the cell though the function is the same but structure is different, the plant cell has chloroplast which contains the green pigment chlorophyll. Besides this, the plant cell has a cell wall and large vacuole which are absent in  animal cells. However, in respect to the life cycle of plants and animals, many animals go through larval stages before they metamorphose into adults whereas plants do not have a larval stage. Thus, the correct answer is option B.

  1. Mammals

  2. Crocodilians

  3. Turtles

  4. Snakes

  5. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Cladistic taxonomy is a way of grouping organisms on the basis of shared features which then are branched out as individual characteristics begin to differ. Birds such as archosaurs are placed along with crocodilians and many species of extinct dinosaurs.
The correct answer is 'crocodilians'.

Multiple choice biology organization of life comparison of prokaryotic vs eukaryotic cells prokaryotic cell and eukaryotic cell types of cell

Which of these statements is/are true?


(i) The surface area available for cellular functions in a prokaryotic cell is less than that in a eukaryotic cell.
(ii) The total genome size of a prokaryotic cell is always less than that of a eukaryotic cell.
(iii) Unlike eukaryotes, no special respiratory organelles are found in prokaryotes. Hence they respire at a much less rate than eukaryotes.
(iv) Eukaryotic cells show various membrane-bound organelles such as chloroplasts and nucleus while ribosomes are the only membrane-bound organelles found in prokaryotes.

  1. (i) and (ii)

  2. (iv) only

  3. (iii) only

  4. (i), (ii) and (iv)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cellular and genomic organisation of prokaryotes are fundamentally different from that of eukaryotes. 

  • Prokaryotic cells have a small, simple structure compared to eukaryotic cells. They have less surface area per volume. Prokaryotes have simpler and smaller genomes than eukaryotes. In the majority of prokaryotes, the genome consists of a ring of DNA with few associated proteins. 
  • The eukaryotic genome is larger, organised into chromosomes, and is complexed with histone proteins. 
  • Unlike eukaryotes, prokaryotes do not have membrane-bound organelle for respiration but many enzymes needed for cellular respiration are attached to the plasma membrane, which may fold and extend into the cell. Ribosomes are the only cytoplasmic organelles in prokaryotes and they are not membrane-bound.
So, the correct answer is '(i) and (ii)'.
