Question

How would you prove that oxygen is necessary for germination?​

Answer 1

Answer:

Place a wet cotton wool in each flask with some soaked Pea seeds. ... In flask A hang a test tube of plain water. Observation: The seeds in flask A germinate because of presence of oxygen and seeds in flask B do not germinate because pyrogallic acid absorbs oxygen. Result: Oxygen is necessary for germination.

Answer 2

Answer:

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.
