Water
Germination requires moist conditions. Mature seeds are usually very dry and need to take up significant amounts of water before they can "come back to life." The uptake of water into seeds leads to a marked swelling. The pressure caused by water aids in cracking the seed coat for germination. When seeds are formed, most plants store large amounts of food, such as starch, proteins, or oils, for the embryo inside the seed. When the seed absorbs water, it breaks down these stored food resources and allows the seedling to germinate and grow until it reaches the light. Once the seedling starts growing, it requires a continuous supply of water and nutrients.
