The diagram below shows specialized plant cells that control openings called stomates. The proper function of these cells is vital to the survival of the plant because they regulate the

• rate of glucose use by root cells

• absorption of sunlight by leaf cells

• products of photosynthesis in the stem

• exchange of gases in leaves

Lymphatic capillaries are found throughout the body. Both the lymphatic and circulatory systems transport substances between the bloodstream and body tissues. These two systems are also involved in fighting infections. The arrows shown in the diagram that go from the blood capillaries to the interstitial fluid most likely represent the

• release of red blood cells, so that they can diffuse into body cells and fight bacteria

• movement of materials from the circulatory system that will eventually enter lymphatic capillaries

• transport of digestive enzymes from the blood to help with the digestion of glucose in muscle cells

• transport of glucose molecules from the blood to be used by cells to attack proteins and fats
