Assertion : Viruses are not considered as organism.
Reason: Viruses are nucleoproteins and lack cell organelle.
1 Both (A) and (R) are correct but (R) is not the correct explanation of (A)
2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of (A)
Explanation:
(d) Virus is a small infectious agent that can only replicate inside the cells of another organism. Viruses are not considered as organisms as they have no independent machinery.

4 Both (A) and (R) are correct and (R) is the correct explanation of (A)
Explanation:
(b) Neurospora belongs to class ascomycetes in which ascospores are produced in sac like 'asci'. Neurospora is commonly called as pink or red bread mould. It can be grown easily in laboratory coñditions so, used in genetics experiments.

Assertion : Chemosynthesis is an autotrophic nutrition.
Reason: Chemoautotrophs contain chlorophyll pigments.

2 (A) is correct but (R) is not correct
3 (A) is not correct but (R) is correct
4 Both (A) and (R) are correct and (R) is the correct explanation of (A)
Explanation:
(b) Chemoautotrophs developed the ability to synthesise organic molecules from inorganic raw materials. Chlorophyll pigments are present in photoautotrophs. The photoautotrophs utilise the solar energy absorbed by them in synthesising organic compounds. Certain chemoautotrophs include green sulphur bacteria.

Explanation:
(d) Two kingdom classification (founded by Linnaeus) worked a long time. But this system did not distinguish between karyotes and prokaryotes, unicellular and multicellular ..ms, photosynthetic and nonphotosynthetic organisms..., classification of organism (into plants and animals) was one and was easy to understand, but a large number of .. did not fall into either category.
