The vegetative cell that forms an endospore is geneticallyidentical
to the vegetative cell that emerges from thatendospore.
true or false?

True

Explanation:

Formation of endospore (sporulation) occurs in some organisms such as bacteria.  Sporulation occurs during unfavourable environmental conditions. Sporulation is a process to preserve genetic material during unfavourable environmental conditions. The vegetative cell forms a thick-coated, dormant and resistant spore called endospore.

Endospore was discovered by John Tyndall. It is a resting spore and helps bacteria to overcome the unfavourable environmental conditions.

On the return of favourable environmental conditions, the endospore germinates to form new bacteria cell. Since this process does not involve meiosis, the new bacterial cell is genetically identical to the original vegetative cell.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
