Here is a detailed description of the process of seed germination:
Seed Germination:
A New Beginning
Seed germination is the process by which a seed begins to grow and develop into a seedling. It is a complex process that involves a series of physical and biochemical changes that ultimately lead to the emergence of a new plant.
Types of Seeds
Dicot
Monocot
Steps Involved in Seed Germination:
1.Water Absorption: The seed absorbs water, which causes the seed coat to soften and swell.
2. Seed Coat Cracking:The seed coat cracks open, allowing the radicle (primary root) to emerge.
3. Radicle Emergence:The radicle grows downward into the soil, anchoring the seed in place.
4.Hypocotyl Elongation: The hypocotyl (stem) begins to grow, pushing the seed coat upward.
5.Cotyledon Expansion: The cotyledons (seed leaves) expand and begin to photosynthesize.
6.Seedling Establishment: The seedling establishes itself, developing roots, stems, and leaves.
Conclusion:
Seed germination is a remarkable process that marks the beginning of a new plant's life cycle. Understanding the steps involved and the factors that affect germination is essential for plant growth and development.
