Activity 5.5 — Nutrition in Amoeba

NCERT Activity 5.5: Observe how Amoeba feeds — pseudopodia engulf food, forming a food vacuole where digestion, absorption, and egestion occur (holozoic nutrition).

How To Perform

1

Pseudopodia Extend

Amoeba extends finger-like projections around the food particle.

2

Food Vacuole Forms

Pseudopodia fuse, engulfing food into a membrane-bound vacuole.

3

Digestion

Enzymes break down complex food inside the vacuole.

4

Absorption & Egestion

Nutrients absorbed; waste expelled from the cell.

⚠️ Safety Notes

  • •Observe Amoeba under a microscope — handle slides carefully.
  • •Use a dropper to transfer Amoeba culture; avoid direct contact with pond water.
