By swimming in watery fluid through the neck of archegonium the sperm reaches to the egg in seedless plants.
The sperm (male nucleus) goes through the pollen tube via micropyle to fuse with the female nucleus.

The union of the sperm and egg cell is caller fertilizationUnion of the egg and sperm cells is called fertilization. The egg then plants itself on the uterin wall. The two sets of DNA combine, then start replicating and dividing to make a baby.
The process when an egg cell and a sperm cell COMBINE is called Fertilization
Sperm is a male gamete and an egg is a female gamete. In plants when the male gametophyte undergoes meiosis it produces four sperm cells. When the female gametophyte goes through meiosis it makes one egg cell and three polar bodies. When the process of fertilization occurs in angiosperms (flowering plants) there is double fertilization. Double fertilization is when one sperm fertilizes the egg and another fertilizes a polar body so that in the seed that develops there is the embryo (fertilized egg), and the endosperm (fertilized polar body, nutrition source for embryo). In animals, eggs are much larger, non-motile, and have a full complement of organelles. They have a larger food store than sperm. Sperm are smaller, flagellated so they can swim, and really only have DNA and mitochondria to power the flagella. Sperm has protein in it's head to dissolve the egg's cell membrane.

Pollen grows inside the flower. The pollen acts as a guard for the egg and sperm of the flower. When pollination occurs and the egg and sperm are placed on another plant, fertilization happens to make more new flowers.

Seed plants:produce seeds Seedless plants:don't produce seeds
sperm
Seedless plants require the liquid water because the sperm has to swim to reach the egg. This is in contrast to most seed plants, that fertilize using pollen transferred by wind or insects.

in almost every female plant there is an ovary chamber that the male flower sperm enters and finds eggs to fertilize. after the egg is fertilized it becomes a seed and the flower "plants" the seed.
