A flexible membrane
What is protplasm?

What is the ectoplasm and describe it?
The outer cytoplasm (ectoplasm) is clear and relatively stiff.
What is the endoplasm and describe it?
The inner cytoplasm (ectoplasm) is grainy due to food vacuoles and waste materials.
It is more fluid than the ectoplasm.
What does the endoplasm contain?
It contains food vacuoles, fat droplets and crystals of waste products.
Explain the contractile vacuole
