AP BIOLOGY

Detailed explanation-1: -Leaves possess stomata – tiny pores, for gaseous exchange. The oxygen consumed via stomata is used up by cells in the leaves to disintegrate glucose into water and carbon dioxide.

Detailed explanation-2: -The process of using glucose to make energy is called cellular respiration. The reactants, or what we start with, in cellular respiration are glucose and oxygen. We get oxygen from breathing in air. Our bodies do cellular respiration to make energy, which is stored as ATP, and carbon dioxide.

Detailed explanation-3: -The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.

Detailed explanation-4: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-5: -Some of the uses of glucose in plants include the glucose made from photosynthesis. Glucose is used for respiration (aerobic and anaerobic). It is also converted into starch so that it can be stored for future energy needs. It is stored in the stem, leaves and roots.
