How do plants grow by themselves?

plant grow them selves by a process called germination i might not be too correct but .. the plants use their stamen and get pollen's by air pollination air pollination is when pollen comes through the air and goes to the plant .from their the plant start shooting ...giving the flower buds that turn into fruit because of this process the plant will absorb more water than it did before plant absorb water into little amount because the water travels through the root in very small tubes and go to the leaves and buds.............
