Seeds grow through a process called germination, where, under the right conditions, a new plant emerges.
The Germination Process
The process begins when a seed absorbs water and oxygen through its seed coat. This triggers the embryo's cells to start expanding. The seed coat then breaks open, and the root emerges first, followed by the shoot. The shoot contains the leaves and stem of the new plant. Sunlight also plays a vital role, as it warms the soil and supports the entire germination process.
Steps of Seed Growth:
- Water and Oxygen Absorption: The seed takes in water and oxygen through the seed coat.
- Cellular Enlargement: The embryo's cells begin to enlarge.
- Seed Coat Rupture: The seed coat breaks open due to the growing embryo.
- Root Emergence: The root emerges first, anchoring the new plant.
- Shoot Emergence: The shoot, containing the leaves and stem, emerges from the seed.
- Sunlight Support: Sunlight warms the soil and further aids the process.
This process is crucial for the continuation of plant life and is affected by several environmental factors such as temperature, moisture, and light availability.
