In the five-kingdom classification, Chlamydomonas and Chlorella have been included in:
1. | Algae | 2. | Plantae |
3. | Monera | 4. | Protista |
Five kingdom system of classification suggested by R.H. Whittaker is based on:
1. Complexity of body organisation
2. Mode of reproduction
3. Mode of nutrition
4. All of the above
Which one of the following living organisms completely lacks a cell wall?
1. Cyanobacteria
2. Sea- fan (Gorgonia)
3. Saccharomyces
4. Coelenterata algae
I: | has non-cellulosic cell wall composed of polysaccharide and amino acids |
II: | has a nuclear membrane but it is not double layered |
Assertion (A): | Amoeba and Paramoecium are included in Kingdom Protista and not in Kingdom Animalia. |
Reason (R): | Unlike animals, a cell wall is present in these organisms. |
1. | Both (A) and (R) are True but (R) does not correctly explain (A). |
2. | (A) is False but (R) is True. |
3. | Both (A) and (R) are True and (R) correctly explains (A). |
4. | (A) is True but (R) is False. |
I: | Bacteria and blue green algae have prokaryotic cell organization unlike other members included in ‘plants’. |
II: | Fungi and many bacteria are heterotrophic unlike autotrophic members included in ‘plants’. |
1. | Only a | 2. | Only b and c |
3. | Only a and c | 4. | Only c |
Statement I: | In the five kingdom classification of Whittaker, there is no mention of lichens, viruses, viroids and prions. |
Statement II: | Lichens, viruses, viroids and prions are all ‘acellular’ organisms. |
