Question

Experts, how are rhizobium and blue green alga different from each other?

Answer 1

Dear student

Cyanobacteria (blue-green algae) are microorganisms that structurally resemble bacteria (they lack a nucleus and organelles ). However, unlike other bacteria, cyanobacteria contain chlorophyll 'a' and conduct oxygenic photosynthesis.
Rhizobium is included in cyanobacteria. The rhizobium has the photosynthetic properties of aerobic anoxygenic phototrophs. It will grow, produce the photosynthetic system and perform photosynthetic electron transport only under aerobic conditions. It can fix nitrogen in ex planta culture and grow in the absence of any other source of fixed nitrogen.
