HORTICULTURE

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: -Seedling growth, which starts when germination is completed, signals a shift in priorities to a rapid growth of root and shoot and establishment of a photosynthetic seedling. In the process, reserve foods are hydrolyzed and provide fuel for energy and building blocks for new macromolecules.
