EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo and controlling embryo growth by acting as a mechanical barrier during seed development and germination.

Detailed explanation-3: -Salt stress reduces a seed’s ability to absorb water (osmotic stress) and causes an ion imbalance within the seed (ionic stress), ultimately inhibiting germination and preventing crop production.

Detailed explanation-4: -Seeds have stored energy in the form of starch which feeds them until the leaves can begin the process of photosynthesis.
