Document Summary
A flowers" o(cid:374)ly purpose is to reprodu(cid:272)e. Like some animals, plants are sedentary (stuck in one spot) Most plants have both sexes: the term perfect flower means that the flower has both sets of reproduction organs. Flower sex organs: stamens (male) produce sperm, pistils (female) produce eggs, stigma (female, style , ovary ( Do plants have an intromittent organ: partially. The wind may not carry the pollen to its target. Plants produce a vast amount of pollen to increase their chances: plants have another way of transporting pollen. Pollinators are animals that deliver pollen for the plants. These include: flies, bats, bees, wasps, hummingbirds, butterflies, moths, hoverflies, etc. Some bees use buzz pollination to shake the pollen from the flowers, which comes out of the poricidal pore. Buzz pollinated plants generally have their stigmas and stamens far away to avoid self- pollination. Some buzz pollinated flowers have an anther cone.
