Restricts the entry of water by osmosis.
Supports and strengthens the cell

Question 2

Endoplasm

Answer 2

Liquid inner cytoplasm in which the cell organelles are suspended

Question 3

Food vacuoles

Answer 3

• Solid food ingested by phagocytosis is digested in the food vacuoles.
• Products of digestion pass from the food vacuole into the cytoplasm
• Indigestible material is egested at the cell membrane

Question 4

Pseudopods

Answer 4
