We need a picture or something
Answer:
Cell wall ; cellulose ; gives strength to cell
Plasma membrane ; phospholipids and protein; selective membrane
Explanation:
The plasma membrane is the living boundary of a cell and is made of a phospholipid bilayer with embedded proteins. It is selectively permeable membrane and regulates the movement of substances across the membrane.
The cell wall is the outer boundary of the plant cells. It is rigid, permeable and made of cellulose, a polymer of carbohydrate. The cell wall gives strength to the cell.
C - The water molecules with a higher speed are escaping
The temperature of a substance is a measure of the average kinetic energy of the molecules. Therefore as the higher speed molecules escape (by evaporation - that is the breaking of the bonds between the molecule and the rest of the liquid), the average KE of the skin decreases and hence the temperature decreases.
It passes directly into the alveoli.
