Mitosis is the cell division used to replace the old cell.
This type of cell division is used when a cell needs to be replicated into exact copies of itself. The new cell (Two in number) is totally duplicate of the original one. The new two cells are called daughter cell while as original one is called mother cell.
The process by which an endospore rehydrates and begins cellular metabolism is termed germination.
Endospore is the dormant form of asexual reproductive structure. It has a tough outer layer that is resistant to various unfavorable conditions, harmful chemicals, therefore protecting the inner contents. The endospore's tough layer breaks off only when the favorable conditions arrive.
Germination is the process where the dormancy of a seed or a spore breaks off and the enzymes present inside get activated. The outer protective payer of the endospore breaks off. After that the spore regains all its functionalities and the cell division begins.
