In five kingdom classification, which single kingdom contains blue-green algae, nitrogen-fixing bacteria and methanogenic archaebacteria

(1) Monera

(2) Protista

(3) Plantae

(4) Fungi

In five-kingdom classification, unicellular green algae are included in the kingdom

(1) Metaphyta

(2) Protista

(3) Monera

(4) Metazoa

Consider the following regarding the reasons for the fact that now Cyanobacteria are kept in Monera and not in Plantae:

I. They are prokaryotes.

II. The cell wall of cyanobacteria has peptidoglycan.

III. They can fix atomspheric nitrogen

The correct explanations would be:

(1) I and II only

(2) I and III only

(3) II and III only

(4) I, II and III

Which of the following are valid pointers to the demerits of the two kingdom classification proposed by Linnaeus?

I. Euglena has features both of plants and animals.

II. Chlamydomanas is autotrophic but has flagella.

III. Slime molds resemble animals in one phase of their life cycle and plants in the other phase.

(1) I and II only

(2) I and III only

(3) II and III only

(4) I, II and III

Identify the group that is not matched correctly to all the characters shown:

Which one of the following does not differ in E.coli and Chlamydomonas?

(1) Ribosomes

(2) Chromosomal organization

(3) Cell wall

(4) Cell membrane

Which is purely anaerobic?

(1) Algae

(2) Mosses

(3) Fungi

(4) None of these

Kingdom Animalia is characterised by

(1) direct dependence on autotrophs

(2) indirect dependence on autotrophs

(3) absence of chlorophyll

(4) absence of cell wall

1. The biological classification was attempted instinctively
a. to make scientific studies easy
b. to use organisms for our own use
c. to make better understanding of the research running in all over the world
d. to make connection between living and non-living

The first attempt for Biological classification was because of the need to use organisms for our own use. Here which kind of uses are considered?
