प्रश्न
How does an Amoeba obtain its food?
लघु उत्तर
उत्तर
- Endocytosis is used by amoebas to acquire food. Endocytosis is the invagination of a tiny portion of the plasma membrane, which results in the formation of an intracellular membrane-bound vesicle.
- This process typically involves the consumption of food materials. Phagocytosis, often known as cell eating, is the process by which a cell takes in solid particles via its cell membrane.
- In this procedure, Amoeba's cell membrane initiates protoplasmic activities around the meal particle. The mechanisms combine and unite to produce a phagosome.
