Many plants reproduce by seeds. This is the process of sexual reproduction whereby a sperm cell in one plant is transferred to the egg cell of another plant by many different methods of transportation. The wind, fruit, flowers that attract insects--these are all methods of transportation for the sexual reproduction of plants. Some plants reproduce asexually, by means that do not use seeds.
Bulbed plants reproduce both sexually and asexually. Sexual reproduction is through normal flowers and seeds. Asexual reproduction is through a process known as vegetative reproduction whereby the bulb splits and creates multiple smaller bulbs called bulblets. These bulblets separate and sprout as new plants, though they have the exact same genetic code as the parent bulb. These bulbs include the kafir lily, crinum lily, Persian violet, wandflower, wood hyacinth and firecracker plants.
A rhizome is a specialist stem that grows out from the base of a plant beneath the surface of the soil. It moves parallel to the soil for several inches. From this stem sprouts new roots and another plant grows up, sending up a base shoot. Plants that reproduce by sending out rhizomes include the Venus flytrap, purple nut sedge, hops, turmeric and Chinese lantern.
Spores are tiny reproductive cells which, it is believed, were once the primary source of plant reproduction. Now this method is used only by a few species. The plant lets loose many millions of these spores into the air where they are carried by the wind. They can withstand extremes of temperature and long droughts, and once the spore lands in a cool and wet environment, it has what it needs to split and form two cells. These two cells split again and so on until the basic root system of the plant has formed. Such plants include royal fern, male fern, floral fern, licorice fern, haircap mass, cushion moss and rockcap moss.
