Germination:
Germination refers to the process by which a seed grows into a new plant. This process involves several steps, including the absorption of water, the activation of enzymes, and the growth of the embryonic plant.
Steps of Germination:
1. Absorption of Water:
When a seed is planted in soil, it absorbs water from the surrounding environment. This water initiates a series of chemical reactions within the seed, which ultimately leads to the growth of a new plant.
2. Activation of Enzymes:
Once the seed has absorbed enough water, it begins to activate enzymes that are stored within its cells. These enzymes break down stored nutrients within the seed, such as starch and protein, into smaller molecules that can be used by the growing plant.
3. Growth of Embryonic Plant:
As the seed begins to break down its stored nutrients, the embryonic plant inside the seed begins to grow. This growth is fueled by the nutrients that are being released by the seed's enzymes.
4. Emergence of the Seedling:
Once the embryonic plant has grown large enough, it begins to emerge from the seed. The first part of the plant to emerge is usually the shoot, which grows upward toward the surface of the soil. The shoot eventually develops leaves, which are used to capture sunlight and produce energy through photosynthesis.
5. Development of Roots:
As the shoot grows upward, the embryonic plant also begins to develop roots. These roots grow downward into the soil and absorb water and nutrients from the surrounding environment. The roots also anchor the plant in place, ensuring that it remains upright as it grows.
Conclusion:
In summary, germination is the process by which a seed grows into a new plant. This process involves several steps, including the absorption of water, the activation of enzymes, and the growth of the embryonic plant. By understanding the process of germination, we can better understand how plants grow and develop, and how we can help them thrive in a variety of environments.
Define germination?
The process of attaining growth phase from the resting phase in plants is called as germination. This process results in the emergence of seedling from the seed.
