The mitochondria is the powerhouse of a cell. They are important because they are an energy factor for both plant and animal cells. They take the food you eat, and turn that as energy for the rest of the cell to use. It is critical that every cell has one to survive whether plant or animal.
Natural selection is the process in which a weaker, or less advantaged animal loses something to a stronger, more advantaged animal. For example, a frog with a broken leg probably will not get to mate while a healthy frog will. Evolution is the process of an animal gradually changing over the generations biologically. An example of this is the theory that humans slowly evolved from monkeys, gradually becoming more and more human like.
