Question

How does ingestion occur in unicellular animals like Amoeba?

Answer 1

HEY MATE!!!

■ Amoeba takes in food using temporary finger like extension of the cell surface which fuse over the food particle forming a food vacuole.

■ Inside the food vacuole,complex substances are broken down into simpler ones which then diffuse into the cytoplasm.

■ The remaining undigested material is moved to the surface of the cell and thrown out.

HOPE IT HELPS YOU!!!

Answer 2

Dear Student,

◆ Ingestion occur in amoeba -

• Amoeba have foot like projections called pseudopodia.
• Ingestion of food in amoeba takes place by process of endocytosis (specifically phagocytosis).
• Pseudopodia wrap around the food particle and form a bag-like structure food vacuole.
• This is how food ingestion takes place in unicellular organisms like amoeba.

Thanks dear. Hope this helps you...
