Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In cytokinesis of plant cells, what structure is formed to divide the parent cell to form daughter cells?
A
Metaphase plate
B
Cell plate
C
Cleavage furrow
D
kinetochore
Explanation: 

Detailed explanation-1: -Rather than a contractile ring dividing the cytoplasm from the outside in, the cytoplasm of the plant cell is partitioned from the inside out by the construction of a new cell wall, called the cell plate, between the two daughter nuclei (Figure 18-37).

Detailed explanation-2: -Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-3: -During telophase, membrane-enclosed vesicles derived from the Golgi apparatus migrate to the center of the cell where the metaphase plate used to be and fuse to form a cell plate. Gradually, the growing cell plate fuses with the existing plasma membrane, producing two daughter cells, each with its own plasma membrane.

Detailed explanation-4: -In cytokinesis, the cytoplasm of the cell is split in two, making two new cells. Cytokinesis usually begins just as mitosis is ending, with a little overlap. Importantly, cytokinesis takes place differently in animal and plant cells.

Detailed explanation-5: -Cytokinesis is the process following the division of the nucleus, the cytoplasm and plasma membrane are divided, resulting in two cells, each with its own nucleus and cytoplasm surrounded by a plasma membrane. It occurs in both plant cells and animal cells.
