Answer:
The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.
The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.

Explanation:
Psychrophile is a type of organism and bacteria that can grow and reproduce in very low temperatures. Besides low and cold temperatures these organisms adapt to high pressure and high concentrations of salt. Their body has adapted to these types of harsh environments by having a body that keeps them from freezing. Their enzymes had evolved to engage in activities such as activity-stability-flexibility as a method for adapting to the cold. This type of bacteria can grow in refrigerated temperatures and they could be found in foods and dairy products.
Cell membrane is the largest. Most important. Of course all cells are different and shape size also. they all have difference.
