For nostoc which of the following characters are true?i) N2 fixation,i...
For the organism Nostoc, the following characters are true:
i) N2 fixation: Nostoc is a nitrogen-fixing organism, meaning it has the ability to convert atmospheric nitrogen gas (N2) into a usable form like ammonia or nitrate. This process is essential for the growth of plants and other organisms.
ii) Non-oxygenic photosynthesis: Nostoc is a photosynthetic organism that uses light energy to convert carbon dioxide into organic compounds. However, it differs from typical oxygenic photosynthesis as it does not produce oxygen as a byproduct.
iii) Decomposer: Nostoc is not primarily a decomposer. It is a type of cyanobacteria that forms colonies or filaments and can be found in various habitats such as soil, water bodies, and even on rocks.
iv) Store food similar to plants: Nostoc stores food in the form of glycogen, which is similar to how plants store starch. This allows Nostoc to survive unfavorable conditions and enables it to resume growth when conditions become favorable again.
v) Production of antibiotics: Nostoc is known for producing a wide range of bioactive compounds, including antibiotics. These compounds play a role in protecting the organism from other microorganisms and may have potential applications in medicine.
vi) Peptidoglycan cell wall: Nostoc possesses a cell wall composed of peptidoglycan, which is a characteristic feature of bacteria. The peptidoglycan provides structural support and protection to the cell.
Based on the given options, the true characters for Nostoc would be:
c) I, IV, V, VI
Explanation:
- Option a) (I, II, IV) is incorrect as Nostoc does not perform oxygenic photosynthesis, but it does store food similar to plants.
- Option b) (I, VI) is incorrect as it does not include the production of antibiotics and the fact that Nostoc is not primarily a decomposer.
- Option d) (I, II, III, IV) is incorrect as Nostoc does not function as a decomposer.
Therefore, option c) (I, IV, V, VI) is the correct answer as it includes all the true characters of Nostoc.

Therefore, option c) (I, IV, V, VI) is the correct answer as it includes all the true characters of Nostoc.
