The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.
<h3>Cell cycle checkpoints</h3>
There are 3 regulatory checkpoints in the life cycle of cells:
- G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
- G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
- M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

Explanation:
Answer:
Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.
Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.
Explanation:
Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.
Active transport, which occurs at the expense of energy.
