Detailed explanation-1: -Water plays an important role in seed germination. It helps by providing necessary hydration for the vital activities of protoplasm, provides dissolved oxygen for the growing embryo, softens the seed coats and increases the seed permeability.
Detailed explanation-2: -Water is necessary for germinating the seeds of a plant. All the nutrients that plants need are soluble in water. The roots absorb the nutrients dissolved in water. Plants need water for photosynthesis.
Detailed explanation-3: -The water is then used in chemical reactions inside cells in the seed. Warmth is needed to speed up the chemical reactions that take place in the seed. Warmth also speeds up the making of new cells when the plant embryo is growing. Therefore low soil temperatures for example, will slow down the rate of germination.
