Germination of the seeds

The germination of the seeds

Germination is defined as the process by which a plant grows from a seed into a seedling. Seeds remains dormant until conditions are favorable for germination.

• All seeds need water, oxygen and optimal temperature to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo's cells start to enlarge, then the seed coat breaks open and the root emerges first, follow by the shoot that contains the leaves and stem.

Sunlight supports the germination process by warming the soil. Although uncommon some seeds need direct contact with sunlight to germinate. Once the leave has spouted, sunlight is the primary energy source for the plant growth through the process of photosynthesis. A seed has everything it needs to begin a new life. Inside the seed coat, is an embroidery plant composed of an embryonic root, stem and leaves. Additionally, the seed contains a food supply called the endosperm that is packed with nutrients to keep the seed nourished and allow it to grow.

As the embryonic plant develops the seed leaves, or cations, absorb the food supply and continue to nourish the plant. Onces the leaves appear the plants begins to make its own food through the process of photosynthesis. With their seed coats protecting the delicate plant embryos within seeds are unique structures. Many seeds are able to endure long period of drought heat or freezing temperature yet are ready to spring to life when favorable conditions arise.
