AP BIOLOGY

Detailed explanation-1: -This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight.

Detailed explanation-2: -Inside the chloroplasts within leaves, light, water (H2O), and carbon dioxide (CO2) are transformed into energy and sugar (glucose). Using water, sunlight is converted into energy-storing molecules within the plant cells. The energy from these molecules is then used to create glucose from CO2.

Detailed explanation-3: -Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.

Detailed explanation-4: -Glucose made by the process of photosynthesis may be used in three ways: It can be converted into chemicals required for growth of plant cells such as cellulose. It can be converted into starch, a storage molecule, that can be converted back to glucose when the plant requires it.

Detailed explanation-5: -Using the molecules produced in the light-dependent reactions–ATP for energy and NADPH for electrons–the Calvin cycle uses a cyclical series of biochemical reactions to convert six molecules of carbon dioxide into a molecule of glucose.
