During this stage the basil plant grows to about 12 inches tall and has the most leaves.

An individual plant begins with the germination of a spore which grows into a gamete producing organism the gametophyte. Although it has been long discredited empirically viable modern versions of haeckel s biogenetic law exist. Seed the plant life cycle starts with a seed from the outside seeds are protected by a tough layer called outer coat but inside every seed there is a tiny baby plant known as an embryo the embryo has a root shoot as well as the first true leaves.

In the fern sporangium the diploid parent cells are the spore mother cells and their haploid daughter cells are the spores. The ability to reproduce both sexually and asexually gives plants the flexibility to adapt to changing environments. During meiosis a single diploid parent cell divides to give rise to four haploid daughter cells. Their complex life cycle allows for great variation.
