Examples of the conditions factors that plants need to germinate Water Helps the seed to swell up so that the embryo can start growing.
When water is plentiful the seed fills with water in a process called imbibition. This process begins with the entry of water into the seed which is known as imbibition which will allow the tissues inside the seed they are hydrated enough so that the embryo swells and the cover or shell of the seed breaks. After some time the plant bears flowers.

The process of seed germination is carried out in all higher plants which influences both crop yield and quality. Embryo the young root and shoot that will become the adult plant. Seed absorbs water oxygen.
Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. The complete process of seed germination is carried out in different steps under favourable conditions. Some seeds are dry and require the intake of a significant amount of water.
