Sexual reproduction takes place when two parents contribute half their genome in sex cells that come together to produce a new organism. Sexually through seeds producing new and interesting hybrids. These need to be left to self-seed. Cell division is how organisms grow and repair themselves. They then make new flowering stalks. Because this one plant produces new offspring that are genetically identical, bulbs are a form of vegetative propagation. In many plant groups, fragmentation of the plant body, followed by regeneration and development of the fragments into whole new organisms, serves as a reproductive system. We also see this in plants that are affected by diseases - those plants that are genetically identical are more likely to die out than those plants that are genetically diverse. In asexual reproduction, a single organism produces offspring that are genetically identical to the parent.

Twins happen when 2 egg cells get fertilized at the same time. Asexual reproduction is all about exploiting a good niche. One convenient classification of organisms sets plants apart from other forms such as bacteria, algae, fungi, and protozoans.
