Cleavage is cell division without cell
Question
Cleavage is cell division without cell
Solution
Cleavage is cell division without cell growth. In this process, the cell divides into two or more smaller cells without increasing in size. This is a common process in early embryonic development. Here are the steps:
-
The parent cell's nucleus, containing the cell's DNA, duplicates its genetic material, resulting in two identical sets of chromosomes.
-
The cell's cytoplasm begins to divide, and a cleavage furrow forms in the middle of the cell.
-
The cleavage furrow deepens and eventually splits the cell into two separate cells, each with its own nucleus and identical set of chromosomes.
-
These new cells, or daughter cells, are smaller than the original parent cell because the cell's size did not increase before division.
-
The daughter cells can then continue to divide by cleavage if more cells are needed.
This process is different from typical cell division, or mitosis, where the cell grows in size before dividing.
