Explain nutrition in Amoeba???
Answers
Actually, amoeba has an outer layer or a muscular organ called the pseudopodia (singular pseudopodium) which engulfs its nearby organism or a small plant cell and gets its nutrition. After all the metabolic activities in its body, amoeba also releases the waste as other organisms.
Amoeba follows Holozoic mode of nutrition in which the solid food particles are ingested, which are then acted upon by enzymes and digested.
Amoeba consumes food by creating temporary finger-like projections of its body surface called pseudopodia. When the pseudopodium fuses with the food particle, it forms a food vacuole. Complex substances are broken down into simple substances inside the food vacuole. Then these simple substances are diffused into the cytoplasm. The remaining unwanted material is taken to the cell surface and is thrown out.
