Plants can reproduce asexually or sexually.

To reproduce asexually, plants use rhizoids, fragmentation, or budding.

The male and female plant organs are involved in sexual reproduction. The female structures involved are  stigma, style and ovary. The male structures involved in sexual reproduction are filament and anther. The anther 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. After fertilization, the zygote divides several times to form an embryo within the ovule.
