Detailed explanation-1: -Photosynthesis in leaves supplies the plant with the energy and matter it needs to grow. Newly germinated seedlings, however, are not yet photosynthesizing. Instead, in early stages of growth, the embryo digests and assimilates the energy and matter from the food present in the seed.
Detailed explanation-2: -Seeds need oxygen so that they can produce energy for germination and growth. The embryo gets energy by breaking down its food stores. Like all organisms, this is done through a process known as aerobic respiration.-a series of reactions where energy is released from glucose, using oxygen.
Detailed explanation-3: -Seeds have stored energy in the form of starch which feeds them until the leaves can begin the process of photosynthesis. In some ways they can be compared to batteries, holding energy until it is needed. Seed size and planting depth impact the process of germination because they affect the seeds energy stores.
Detailed explanation-4: -The process of the growth of a plant (in this case, the seedling) from the seed is called germination. Seeds germinate in the presence of suitable environmental conditions. They require air, water, soil, and sunlight for germination. If a seed is sowed too deep in the soil, it will not germinate.
