Endospores are dormant alternate life forms produced by the genus Bacillus, the genus Clostridium, and a number other genera of bacteria, including Desulfotomaculum, Sporosarcina, Sporolactobacillus, Oscillospira, and Thermoactinomyces.
Certain bacteria produce endospores. Bacillus and Clostridium are endospore producing bacteria. Process of forming a spore is known as sporulation. Spores produced inside the bacterial cell are known as endogenous spores.Spores are differentiated cells. Endospores may survive for millions of years.f the plant has two types of spores, male and female spores, it is known as heterospory. Male spores are called microspores and female spores are called megaspores. Micro spores are also called pollen grains. In flowering plants, microspores are found inside the pollen sac or the microsporangium.
