Question

Describe physical division of cytoplasm during cytokinesis in
i) Animal cell ii) Plant cell

​

Answer 1

i)During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

ii)Plant cells have walls, so cytokinesis cannot proceed with a cleavage furrow. ... Eventually, the growing cell plate fuses with the existing plasma membrane, producing two daughter cells, each with its own plasma membrane. A new cell wall forms between the two membranes of the cell plate.

Answer 2

Cytokinesis is the process of cytoplasm being divided in eukaryotic cells to produce two distinct daughter cells that are identical to each other. It occurs at the end of the parent cells cycle after meiosis or mitosis when a cleavage furrow or a cell plate is constructed to divide the cell membrane into two new cells.
