Expert Answer:

Sexual reproduction in plants involves male and female plant organs. The female structures invovled in sexual reproduction are the stigma, the style and the ovary. The stigma is the sticky portion of the pistil that captures pollen. The style is long and slender and supports the stigma. The ovary is composed of one or more ovules and is responsible for housing the eggs. The male structures involved in sexual reproduction are the filament and the anther. The filament supports the anther which is responsible for storing and producing pollen. Pollination is the transfer of pollen from an anther to a stigma. Wind, water, insects, birds, and small mammals all aid in the pollination of plants. After pollination, one nuclei of the pollen grain forms a tube down through the style to the micropyle of the ovary. The second nuclei travels down the tube and splits into two sperm nuclei that fertilize the egg and combine with polar bodies to form the endosperm (stored fruit). After fertilization, the zygote divides several times to form an embryo within the ovule.
