Often, small drainage basins or watersheds combine with one another, creating larger and larger networks of drainage basins. All of these combined drainage basins are together referred to simply as a drainage basin, or as one watershed. The area between two drainage basins is known as a drainage divide.ften, small drainage basins or watersheds combine with one another, creating larger and larger networks of drainage basins.

The fertilized ovules will mature into seeds, which are the starting point of the next generation of plants. Fruits are the ripened ovary of a flower and protect and help disperse the seeds by attracting dispersers.Movement of pollen often also involves specialized pollinators including insects, reptiles, birds, bats, and other mammals. Flowers evolved colors, patterns, scents and nectar rewards to attract pollinators.icture 9: The male reproductive parts of a cherry flower. The female reproductive part of a flower, the gynoecium, is composed of one or more carpels. A carpel is made up of a stigma, a style, and an ovary. The ovary houses the ovules that will develop into seeds after fertilization.
Seed dispersal is the movement or transport of seeds away from the parent plant. Plants have very limited mobility and consequently rely upon a variety of dispersal vectors to transport their propagules, including both abiotic and biotic vectors.eed dispersal is the movement or transport of seeds away from the parent plant.
