An endospore is an extremely resistant dormant cell structure produced by some bacterial species. If you break down the term endospore, 'endo-' means 'inside' and '-spore' refers to the 'dormant structure,' so the endospore is a structured formed inside the cell.
Bacterial endospores are formed when cells find themselves in such extreme conditions that they are in peril of dying. In order to survive harsh conditions the cell prepares and endospore where it packs everything needed to survive until conditions improve. When a bacterial cell is thriving and life is good, it is called a vegetative cell.
