Activity 5.6 — Nutrition in Paramecium
NCERT Activity 5.6: Observe how Paramecium feeds — cilia sweep food into the oral groove, through the gullet, into a food vacuole for digestion (holozoic nutrition).
How To Perform
1
Cilia Sweep Food
Rhythmic cilia beat creates water currents toward the oral groove.
2
Food Enters Oral Groove
Food particles slide down the oral groove to the gullet.
3
Food Vacuole Forms
A food vacuole pinches off from the gullet into the cytoplasm.
4
Circulation & Digestion
Vacuole circulates; enzymes digest; waste exits cytopyge.
⚠️ Safety Notes
- •Observe Paramecium under a microscope — handle slides carefully.
- •Use a dropper to transfer culture; avoid direct contact with pond water.
