A seed is formed when a pollen grain lands on the stigma of the flower, and sends down a pollen tube which
releases a sperm cell into the ovule. This fertilization or joining of the sperm cell and ovule forms a cell
called a zygote. The zygote then develops into an embryo. The embryo along with the food storage
organs, cotyledons and/or endosperm, and the seed coat or testa make up what is called the seed.

sexual propagation
Sexual Plant Propagation needs seeds for it to grow and without seeds the plant will not grow.
Producing new plants from the propagules of existing plant is known as plant propagation. It may be sexual, asexual and vegetative types.
Sexual propagation is a process by which plants reproduce, in which pollen from one plant fertilizes the ovary or ovaries from another, producing one or more seeds. It can be contrasted to asexual propagation in which new plants are created from divided plant parts (cuttings), stolons or runners, storage organs such as bulbs or tubers, or any of a number of other ways.
Some plants can be grown from leaves (leaf cuttings) including: Begonia and Saintpaulina. Most propagation is however done from either seeds (sexual propagation) or cuttings (asexual propagation).
