Cellular respiration is the process by which cells get energy from sugars in the presence of oxygenBoth plant and animal cells undergo cellular respiration to stay alive and to grow. During cellular respiration, sugar is broken down into smaller molecules and combined with oxygen to produce carbon dioxide and water The rearrangement of these molecules releases the energy needed by plants and animals. Write a scientific explanation that explains how oxygen and carbon dioxide travel within the seed and the egg. ( I just need help with the reasoning! )
