Explanation:
Digestion in amoeba is intracellular taking place within the cell. The food taken in remains in a food vacuole or gastric vacuole formed by the cell membrane and small part of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic movements. Here they fuse with lysosomes that contain enzymes. Two enzymes amylase and proteinase have been reported. Thus, amoeba can digest sugars, cellulose and proteins. Fats, however, remain undigested.
The contents of the vacuole become lighter and the outline of the vacuole becomes indefinite indicating that the digestion is complete.
Amoeba eats tiny plants and animals present in pond water. The body of Amoeba has finger-like projections called pseudopodia which ingests the food. When a food particle comes near Amoeba, the pseudopodia surrounds the food particles and trap the food with a little water forming a food vacuole inside its body. The surrounding cytoplasm secretes digestive enzymes into the food vacuole which acts on the food and thus it gets digested.
