Assertion is correct but Reason is incorrect.

Slime moulds possess the characters of both animals and fungi, and, therefore, they are commonly called fungus-animals. They do not have chlorophyll. They are surrounded by the plasma membrane only. They live usually amongst decaying vegetation. Cell organelles are present in slime moulds. Slime moulds are excellent material for the study of protoplasm. The plasmodia of slime moulds are an excellent material for the study of structure and physiology of protoplasm.
