Question

In amoeba the digestion is intracellular because ?​

Answer 1

Answer:

Digestion in amoeba is said to be intracellular because amoeba is a single celled organism, so the digestion takes place inside the cell. It obtains its nutrition in a heterotrophic mode. Amoeba can form pseudopodia. It engulfs the food with its pseudopodia. When the food enters its body, the amoeba forms a food vacuole around it which contains certain enzymes to digest the food.

Answer 2

Answer:

⇒Digestion in amoeba is said to be intracellular because amoeba is a single celled organism, so the digestion takes place inside the cell. When the food enters its body, the amoeba forms a food vacuole around it which contains certain enzymes to digest the food.

⇒Amoeba is a single cell organism. It consumes food with the help of pseudopodia, which fuse through a food particle to form a food vacuole. Vacuole food contains digestive enzymes.

The engulfed food is digested in the food vacuoles with the help of digestive enzymes. Two amylase and proteinase enzymes have been reported. Therefore, amoeba can digest carbohydrates and proteins.

The undigested food remains in the vacuole food.  

This digested food is a part of the protoplasm. Some food is used to generate energy through the respiration process and the remaining food is stored as a reserved food in the protoplasm.

⇒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.
