Question

Water is not the electron donor during photosynthesis in

Pinus
Chara
Nostoc
Thiospirillum​

Answer 1

Answer:

The Cyanobacteria are the largest and most diverse group of photosynthetic bacteria. They were previously known as ‘blue green algae’. They show following characteristics:

Answer 2

Nostoc is the bacteria that belong to the Phylum cyanobacteria found in water and other environments.

Nostoc is the bacteria that contain photosynthetic pigments in their cytoplasm for Photosynthesis purposes.

• They provide Nitrogen to the other hosts so water is not the electron donor during photosynthesis in Nostoc.

• In some of the higher plants and bacteria such as purple color, bacteria do not produce oxygen in the process of photosynthesis.

• Because water is not the electron donor during photosynthesis. So the right option is 3) Nostoc.
