Explain Slime Moulds of Kingdom Protista

Slime moulds are saprophytic protists. The body moves along decaying twigs and leaves engulfing organic material. Slime moulds expend most of their lives independently, but during food scarcity, they swarm and aggregate into an enormous solitary cell.

Under suitable conditions, they form an aggregation called plasmodium which may grow and spread over several feet. During unfavorable conditions, the plasmodium differentiates and fors fruiting bodies bearing spores at their tips. The spores possess true walls. They are extremely resistant and survive for many years. even under adverse conditions. The spores are dispersed by air currents.
