CYTOSKELETON

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cytoskeleton is missing in
A
Plant cells
B
Bacteria
C
Prokaryotes
D
Both b and c
Explanation: 

Detailed explanation-1: -The cytoskeletal structure that is found in animal cells but not in plant cells, is the actomycin ring. This structure helps to form the contractile ring, and cleavage furrow during cell division. This process only occurs in animal cells, because plant cells create a cell plate.

Detailed explanation-2: -The actin cytoskeleton in plant cells is mostly found within more central regions of the cytoplasm, notably within cytoplasmic strands that cross the vacuole and connect to the nucleus (28). In addition, plant cells lack centrosomes, which leads to diffuse MT nucleation within the cell (SI Appendix, Fig.

Detailed explanation-3: -All cells, except those of most bacteria, contain components of the cytoskeleton. They help the cell remain rigid but also help it move and change its shape when instructed to do so.
