. Define the following term. (i) Fimbriae (ii) Reproduction (iii) Binary fission

Best Answer

Fimbriae:

They are small bristle like fibres which develop from the surface of bacterial cells. They are quite numerous (300-400 cell). They take part in attachment, mutual aggregation or attachment to host tissue. 

Reproduction:

Bacteria reproduces mainly by vegetative and asexual methods of reproduction. However, they also exhibit some amount of genetic recombination.

Binary fission:

This is the universal method of multiplication in bacteria in which the cell divides into two equal parts by a transverse constriction of the cytoplasm.

Then nucleus divides amitotically and the process of binary fission is completed in 20-30 minutes.
