Process of Seed Germination
The process of seed germination involves several key stages. They are as follows:
- Imbibition: Water absorption by the seed is known as imbibition, which is the initial stage of seed germination. The seed swells as a result, and the enzymes required for germination are activated.
- Enzymatic and respiratory activities: Enzymes in the seed are triggered by the water, allowing for the breakdown of food that has been stored there and respiratory activity. Respiration is the process that utilizes the food that has been stored to create the energy the plant needs to thrive.
- Food digestion and translocation: Food is delivered to the growing sections of the plant where it is used as a source of nutrition and energy after being broken down by enzymes in storage. Translocation and digesting are two names for this process.
- Assimilation: The plant uses the nutrients to create new cells that become the stem, leaves, and roots. The term “assimilation” refers to this process.
- Growth: The seed will begin to grow after it has accumulated enough energy. The shoot, or embryonic stem, starts to develop upward towards the surface, while the radicle, or embryonic root, starts to grow downward into the soil. The seed will keep growing in this manner until it becomes a fully-fledged plant.
Seed Germination
The process by which a seed starts to grow and develop into a new plant is known as seed germination. A number of processes, including imbibition, embryo growth, and radicle emergence, take place during the germination of seeds.
