What is seed germination. Explain essential requirement of seed germination?
Answers
Answer:
⛧The development of a Seed into a seedling is called Germination. When a Seed gets right amount of air, water and warmth, it develops into a seedling.
Essential Requirements !!
- Some dry gram seeds.
- Air, water and Sunlight.
- Some soaked Seeds.
Explanation:
⛧During Germination, the seed absorbs water and cells of the embryo start dividing and increasing in size.
⛧Eventually, the seed coat breaks open.
⛧First of all, the root system or radical sprouts grow downwards. This is followed by the growth of the Plumule, a small shoot which grows upwards and produces the stem and leaves forming the shoot system of the plant.
Answer:
All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat.
Oxygen: Aeration of the soil is absolutely necessary for the germination of the seed because oxygen is necessary for the aerobic respiration by which the seeds get the requisite energy for the growth of the embryo.
Temperature: Seeds normally germinate within a wide temperature range.
