Others utilize organic vectors consisting of insects (entomophily), birds (ornithophily), bats (chiropterophily) or various other animals.
Most of plant varieties, individual flowers have both practical carpels as well as stamens. Botanists explain these flowers as “perfect” or “bisexual”, and also the varieties as “hermaphroditic”.
