This document discusses nutrition in amoeba and includes 5 objectives about making the reader aware of how amoeba feeds, its role as a unicellular organism without a definite shape, and the functions of its pseudopodia. It explains that amoeba ingests food like algae, bacteria, and small protozoans using its pseudopodia, and then digestion and absorption of nutrients occurs inside its cytoplasm through food vacuoles and enzymes before wastes are excreted.

3. OBJECTIVES
1.TO MAKE AWARE ABOUT HOW
NUTRITION IN AMOEBA TAKES PLACE.
2.TO MAKE AN AWARENESS THAT
NUTRITION IS ALSO PRESENT IN
MICRO ORGANISMS.
3.TO UNDERSTAND THE FUNCTION OF
PSEUDOPODIA.
4.TO MAKE AWARE THAT AMOEBA IS A
UNI CELLULAR ORGANISM.

BACTERIA
SMALL PROTOZOANS

5. MODE OF FEEEDING
INGESTS FOOD USING PSEUDOPODIA

6. DIGESTION
TAKES PLACE IN THE FOOD VACUOLE FOUND IN
THE CYTOPLASM. THERE ARE ENZYMES THAT
CAN DIGEST STARCH, PROTEINS AND FATS

7. ABSORPTION
THE SIMPLE NUTRIENTS ARE ABSORBED IN TO
THE CYTOPLASM

8. EXCRETION
THE WASTES ARE EXPELLED THROUGH THE
BODY WALL
