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.
