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 fixatmospheric Nitrogen tonitrites and nitrates andrelease 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.
