Another level of genetic variation is added by random fertilization , since we can't predict which sperm will fertilize a given egg.
<h3>What is fertilization?</h3>
A new individual organism or progeny is created when two gametes are fused during fertilization, often referred to as fertilization, impregnation, syngamy, and generative fertilization. The term "fertilization" is often used colloquially to refer to pre-gametic processes like pollination and insemination. The cycle of fertilization and development of new individuals is called sexual reproduction. In the process of vegetative fertilization, the haploid male gamete of an angiosperm fuses with two haploid polar nuclei to create a triploid main endosperm nucleus.

No Water Required
Seeds do not necessarily need water to germinate and grow, although some require water to soften the seed coat. Large seeds in dry conditions will hold water and allow the growing plant to grow deep roots without the need for rain or additional water.
Fully Developed Embryo
Inside each seed is a fully developed embryo that is ready to begin growing. Many seeds go through a dormancy period, which is a period when the seed will not germinate and begin growing. When conditions are right, the embryo germinates and begins growing. Having an embryo already grown gives a seed plant a better chance at survival as opposed to a spore.
Nourishment
Each seed contains nourishment for the embryo inside the seed. The endosperm is the tissue that surrounds the embryo inside the seed. The embryo uses nourishment provided by the endosperm as a jump start to begin growing.
The Seed Coat
The seed coat is one major advantage seeds have over spores. A spore is a single-celled organism that develops into a plant or fungus when the conditions are right. The spore has no outer protection.
