In one sense marijuana plants are like people, because they have separate sexes. There are male plants that produce pollen and female plants that produce eggs and seeds. Male plants contain the anther (pollen producing/containing organ) and the filament hair-like stalk the anther rests on. On the female plants you will find a stigma (a sticky bulb found in the middle of flowers that will catch the pollen), the style (a stalk the stigma rests on), the pistol (a tube leading to the ovary), the ovary (the part of the plant that houses the seeds and will become the bud containing high densities of Delta 9 tetrahydrocannabinol or THC), and lastly, the ovule which will become the seeds. Although most plants are either male or female, some marijuana plants will possess both sets of organs. These plants are referred to as Hermaphrodites. - Bio Web
