explain seed germination
Answers
Answer:
Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. ... Under proper conditions, the seed begins to germinate and the embryo resumes growth, developing into a seedling.
Answer:
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.
A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.
Explanation:
During the beginning stage of germination, 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. It starts the growth process by activation of enzymes. 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.
By rupturing of the seed coat, radicle emerges to form a primary root. The seed starts absorbing underground water. After the emerging of the radicle and the plumule, shoot starts growing upwards.
In the final stage of seed germination, the cell of the seeds become metabolically active, elongates and divides to give rise to the seedling.
