Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In plants cells, what is the structure that forms in between the divided nuclei?
A
cell membrane
B
cell plate
C
cleavage furrow
Explanation: 

Detailed explanation-1: -Plant cells divide in two by constructing a new cell wall (cell plate) between daughter nuclei after mitosis. Golgi-derived vesicles are transported to the equator of a cytoskeletal structure called a phragmoplast, where they fuse together to form the cell plate.

Detailed explanation-2: -2.4 Phragmoplast. The phragmoplast is the structure that builds a cell wall (called as “cell plate”) between daughter cells.

Detailed explanation-3: -In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast. A cell plate formed by the fusion of the vesicles of the phragmoplast grows from the center toward the cell walls, and the membranes of the vesicles fuse to form a plasma membrane that divides the cell in two.

Detailed explanation-4: -Plant cells can’t be divided like this because they have a cell wall and are too stiff. Instead, a structure called the cell plate forms down the middle of the cell, splitting it into two daughter cells separated by a new wall.

Detailed explanation-5: -Plant cells undergoing cytokinesis (cytoplasmic division) form a cell plate in the center of the phragmoplast. The phragmoplast consists of both cytoskeletal and membranous elements.
