BACTERIA

SMALL PROTOZOANS

MODE OF FEEEDING

INGESTS FOOD USING PSEUDOPODIA

DIGESTION

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

ABSORPTION

THE SIMPLE NUTRIENTS ARE ABSORBED IN TO THE CYTOPLASM

EXCRETION

THE WASTES ARE EXPELLED THROUGH THE BODY WALL
