[00:00:00]Seed germination is the process where a seed starts growing into a new plant. It needs three main conditions: water, oxygen, and a suitable temperature. The first stage begins when the seed absorbs water and swells. The seed coat softens and breaks open. The root, called the radical, grows downward into the soil.

There are two main types of germination: epigeal germination, where the seed leaves come above the soil, and hypogeal germination, where the seed leaves stay below the soil.
