Seeds are the main means by which flowering plants reproduce and spread. After the plant has been fertilized the egg cells develop into a seed from which a new plant can develop. The seed contains an embryo from which the new plant will grow. It also contains a food store to nourish the embryo until it has developed roots and leaves. The seed is enclosed in a tough outer coating to protect it from drying out. Many seeds can be carried by the wind. Some even have a fluffy umbrella like the dandelion seed head, which enables them to be carried for very long distances.

The biggest seed is the coco de mer, a kind of coconut that grows in the Seychelles, a group of islands in the Indian Ocean. The coco de mer seeds weigh 250 kg each.
