Arrange the following sequential stages of holozoic nutrition and intracellular digestion in *Amoeba proteus* from the initial capture of food to the elimination of waste.
- 1Extension of pseudopodia to surround and capture the food particle
- 2Enclosure of the food particle within a pinched-off intracellular food vacuole
- 3Discharge of hydrolytic digestive enzymes into the food vacuole by lysosomes
- 4Absorption of soluble nutrients across the vacuolar membrane into the cytoplasm
- 5Exocytosis of insoluble residual waste through the cell membrane to the exterior
Cevap
The correct chronological sequence of holozoic nutrition in *Amoeba proteus* is: Extension of pseudopodia to capture food → Enclosure of food within a food vacuole → Discharge of hydrolytic enzymes by lysosomes → Absorption of soluble nutrients into cytoplasm → Exocytosis of insoluble residual waste.
Holozoic nutrition in *Amoeba* follows a strict sequence: pseudopodia surround the food, a food vacuole forms around it, lysosomes release digestive enzymes into the vacuole, digested soluble nutrients are absorbed into the cytoplasm, and finally undigested waste is egested via exocytosis.
