Question

What is germination with diagram?

Answer 1

Germination:

1. Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality.
2. A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.

The complete process of seed germination is carried out in the following steps:

1. Initially, the seeds take up water rapidly and this results in swelling and softening of the seed coat at an optimum temperature, this stage is referred to as imbibition.
2. It starts the growth process by the activation of enzymes.
3. The seed activates its internal physiology and starts to respire and produce proteins and metabolizes the stored food, this is a lag phase of seed germination.
4. A radicle emerges to form a primary root, by rupturing the seed coat.
5. The seed starts absorbing underground water. After the emergence of the radicle and the plumule, the shoot starts growing upwards.
6. In the final stage of seed germination, the cell of the seeds become metabolically active, elongates, and divides to give rise to the seedling.
