Explanation:
Answer:
Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm
Explanation:
A food vacuole is a membrane-enclosed sac in a cell which is formed by the ingestion of the food particle from the outside environment through the process of phagocytosis.
The formation of food vacuole is a feature of the protozoa like amoeba which engulfs its food.
The food vacuole then fuses with the lysosome present in the cell which contains the digestive enzyme and then forms phagolysosomes which can digest the food particles in an enclosed sac.
Thus, the selected option is the correct answer.
Answer:
option B because
Explanation:
The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.
