• B. Amoeba is multicellular
• C. Amoeba is found in a pond
• D. Amoeba is a microscopic animal

Answer 1

The correct option is A Amoeba is unicellular

Amoeba, a protozoan employs intracellular digestion for deriving nutrition. Food is ingested with the pseudopodium by invagination of cell membrane and subsequently stored into the food/gastric vacuole. This due to cytoplasmic movements combine with the lysosome where the food is broken down to simpler products and assimilated. Finally, the waste is removed by exocytosis by the contractile vacuole.
