Question

Why is endospore called "resting?"?

Answer 1

They are dormant and "non-active".

An endospore is a dormant, tough, and non-reproductive structure produced by a small number of bacteria from the Firmicute phylum. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress. They are therefore resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation, and chemical disinfectants. Endospores are commonly found in soil and water, where they may survive for long periods of time.

Answer 2

Yeah.  Only the bacteria Bacillus and Clostridium produce spores, as they are nearing death.  They are Endospores when they have produced the spore internally but the bacteria is still alive and thus has not released it.  Once released, these spores have been known to live up to a hundred years before finding the right conditions to be cultured and grow.
