What is the purpose of a buffer in a chemical solution?
A buffer, in a chemical solutions acts to counteract the pH changes when acids or bases are added. This works up to a certain point however. When too much acid or base is added, the buffer proves as ineffective.
What is the difference between Crassulacean acid metabolism (CAM) plants, and C4 plants?
CAM plants prevents excessive water loss by using a temporal method of separation whereas C4 plants use a spacial method of separation. In CAM plants carbon fixation happens only at night because the plant keeps its stomata, the pores used for gas exchange, closed during to day to prevent its water from evaporating. In C4 plants, the stomata is open at all times. The difference is that it has a separate compartment called a "bundle-sheath cell" where it does its carbon fixation.
