Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In plant cells, what forms in telophase that aids cell division?
A
cell wall
B
centrioles
C
large vacuoles
D
cell plate
Explanation: 

Detailed explanation-1: -(C) Vesicles fuse together in the center of the division zone and form the cell plate, which is the beginning of the cell wall.

Detailed explanation-2: -Telophase. In telophase, the nuclear membrane forms around the chromosomes in each of the daughter cells, a cell plate forms between these cells, and cell walls separate the newly formed cells in a process called cytokinesis .

Detailed explanation-3: -Plant cells undergoing cytokinesis (cytoplasmic division) form a cell plate in the center of the phragmoplast.

Detailed explanation-4: -The cell plate is built in the center of phragmoplast by fusion of Golgi-derived vesicles.

Detailed explanation-5: -During telophase, the chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form. The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
