how can we say that rhizobium bacteria and leguminous are example of Symbiosisk
Answers
Answer:
The symbiosis between rhizobia soil bacteria and legumes is facultative and initiated by nitrogen starvation of the host plant. Exchange of signal molecules between the partners leads to the formation of root nodules where bacteria are converted to nitrogen-fixing bacteroids
:In this mutualistic symbiosis, the bacteria provide nitrogen sources for plant growth in return for photosynthates from the host. Depending on the host plant the symbiotic fate of bacteria can either be reversible or irreversible.
Answer:
In easy way we can say that, rhizobium bacteria is present in the roots of leguminous plants. The nitrogen, present in the atmosphere, is an essential part of photosynthesis. Plants cannot take the nitrogen straight from the atmosphere. The rhizobium bacteria traps the nitrogen and converts it into suitable form. The plants absorb nitrogen with water. And the palnt gives food to the bacteria. And this way we can say that rhizobium bacteria and leguminous plants are symbiotic.
