Q.2 Answe the following
1) what is totipotency ?
2) Name the component of prokaryotic cell wall?
Answers
Answer:
1)Ability of the cell to form complete organism is called totipotency.
2) Peptidoglycan
Explanation:
1) Totipotency is exhibited by the pant cell when suitable conditions werre provided each cell has the ability to form the new plant this is the principle behind the tissue culture.
Where the tissue from the root or shoot is taken which is known as explant and under lab they provide with nutrients and hormones require and they form the new plant.
2) Peptidoglycan is the component of cell wall of bacterial which is complex hetero polysaccharide with repeating unit of sugars know as NAG and NAM.
Answer:
1.Totipotency is defined in Wikipedia as the ability of a single cell to divide and produce all the differentiated cells in an organism, including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes.
2.The major component of the bacterial cell wall is peptidoglycan or murein. This rigid structure of peptidoglycan, specific only to prokaryotes, gives the cell shape and surrounds the cytoplasmic membrane.
