Difference between Rhizobium and Cyanobacteria

NCERT Biology Note:

Bacteria

Bacteria are the single cellular, prokaryotic organisms that contain cell walls. They are found everywhere.

Bacteria

Types of Bacteria. These include autotrophic bacteria, parasitic bacteria, saprophytic bacteria and symbiotic bacteria.

Bacteria

Symbiosis is a kind of interaction where organisms benefit from each other.

Symbiosis

Bacteria

Rhizobium is a bacterium that is symbiotically associated with leguminous plants.

Rhizobium

Bacteria

Cyanobacteria are  free living soil bacteria, but sometimes symbiotically associated with plants.

Cyanobacteria

Bacteria

Rhizobium and Cyanobacteria both are  soil bacteria.

Differences Between Rhizobium and Cyanobacteria:

Bacteria

Both bacteria are capable of converting atmospheric Nitrogen to nitrites and nitrates which are available to plants. Generally these bacteria obtain energy through this process.

Bacteria

Rhizobium lives in the root nodules of leguminous plants.

Bacteria

Cyanobacteria is a  free-living bacterium, but sometimes it is symbiotically associated with some plants. Example: Hornworts of bryophytes, cycads of gymnosperms, gunners of angiosperms.

Bacteria

Rhizobium fixes nitrogen and supplies to leguminous plants and leguminous plants provide food to Rhizobium bacteria.

Bacteria

Cyanobacteria fix atmospheric Nitrogen to nitrites and nitrates and release into the soil.

Bacteria

But symbiotic   cyanobacteria fix Nitrogen   and supplies to plants and   Bacteria get shelter.

Bacteria

Free living Rhizobium     bacteria live in the soil. Some Cyanobacteria are     symbiotically associated     with some fungi to form     lichens.
