What is true for cleavage
What is true for cleavage
- Size of embryo increase
- Size of cells decrease
- Size of cells increase
- Size of embryo decrease
The Correct Option is B
Solution and Explanation
The correct option is (B) : Size of cells decrease
The zygote splits frequently during cleavage to separate the enormous cytoplasmic bulk into several tiny blastomeres. Because cells are still held within the zona pellucida, it includes cell division without size increase. However, during cleavage, cell size reduces.

Cell Cycle and Cell Division
Cell Cycle:
The sequence of events by which a cell copies itself synthesizes other constituents of the cell and eventually splits into two daughter cells is termed the cell cycle. The cell synthesizes all its constituents in a sequential pattern to make sure the proper division and distribution of components that occurs between the two daughter cells. Therefore, we can say that the cell cycle is the period of time between the development of new daughter cells and their further division.
Stages of Cell Cycle:
The cell cycle can be sub-divided into an additional category of Interphase. Meanwhile, the Interphase can be branched into 3 further stages, such as:
- G1 Phase - “Gap 1 Phase”
- S Phase - "Synthesis Phase"
- G2 Phase - "Gap 2 Phase"

Cell Division:
The division of the parent cells into two or more cells is called daughter cell, cell division takes place. In general, it occurs as a part of a larger cell cycle. All the cell reproduces by dividing into two, wherein each parental cell produces two daughter cells.
Stages of Cell Division:
Cell division can be widely divided into several sub-segments that result from Mitosis and Meiosis.
- Mitosis or (M Phase)
- Meiosis
