The generative cell divides to form two sperm that move down the pollen tube. The pollen tube provides a pathway for the sperm to reach the egg cell in the ovule. One sperm fertilizes the egg cell and together they form the zygote. The other sperm unites with the polar bodies in the ovule and together they form the nutritive tissue for the zygote. An embryo plant and cotyledon are found inside a seed.
Simple fruits develop from one carpel or carpels that are united.
Aggregate fruits are formed by flowers having several separate carpels. Multiple fruits are a group of many fruits formed by a cluster of flowers. A seed coat forms from the ovule wall to protect the seed. The cotyledon is formed by the combination of the second sperm and the polar bodies. The root of the embryonic plant in the seed is know as the radicle .
