Explanation:

7) The food in amoeba is obtained by the process of endocytosis. Endocytosis is a cellular process where the substances are brought into the cell by a cell membrane surrounding the cell. These cell membranes then break off and form a vesicle surrounding the food material. The amoeba engulfs food with the help of pseudopodia and then it forms a vesicle around it. When the particle is inside the vesicle, amoeba secretes digestive enzymes that digest the food particle.

8) Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides. In other words, osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.
