Let%u2019s Recall%u00be Green plants make food in their leaves by the process of photosynthesis.%u00be Plants take in water and minerals through their roots.%u00be The stem sends the water upwards to the leaves.%u00be Leaves take in carbon dioxide through tiny openings called stomata.%u00be The chlorophyll in leaves absorbs sunlight.%u00be During photosynthesis, green plants combine water and carbon dioxide in the presence of sunlight to make sugar.%u00be Oxygen is released during photosynthesis.%u00be The extra food made by the leaves is stored as starch in roots, stems, leaves, and seeds.%u00be Parasites are plants that depend on green plants for food.%u00be Insectivorous plants eat insects. They also have chlorophyll to prepare their own food.Let%u2019s Revise Conceptual UnderstandingA. Choose the right option.1. The food made in plants is called . a. proteins b. sugar c. fats2.
