7. How does an Amoeba obtain its food?
Answer: Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole as shown in figure. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm. The remaining undigested material is moved to the surface of the cell and thrown out.

8. What is osmosis?
Answer:
 Osmosis is the process in which water molecules moves from the region of high concentration to a region of low concentration through a semi permeable membrane.
