Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Following telophase in animal cells, a cell plate begins to form
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -During telophase and cytokinesis, vesicles collect along the center of the cell and coalesce (or come together), forming the cell plate. As vesicles fuse, the cell plate grows, building a cell wall. The cell plate will continue to grow until it eventually attaches to the plasma membrane.

Detailed explanation-2: -Cytokinesis typically occurs at the end of mitosis, after telophase, but the two are independent processes. In most animals, cytokinesis begins sometime in late anaphase or early telophase, to ensure the chromosomes have been completely segregated.

Detailed explanation-3: -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.

Detailed explanation-4: -The assembly of the cell plate begins in late anaphase and is guided by a structure called the phragmoplast, which contains the remaining overlap microtubules of the mitotic spindle that interdigitate at their growing plus ends.
