Answer 1

All organisms use energy to carry out their life functions. Some organisms obtain this energy from sunlight. The process by which this energy transfer take place is called photosynthesis. Photosynthesis involves a biochemical pathway in which the product of one reaction is consumed in the next reaction. Autotrophs are organisms that carry on photosynthesis and includes plants and other organisms containing the green pigment chlorophyll. Autotrophs use carbon dioxide and water to make oxygen and the simple sugar glucose. The pigment chlorophyll absorbs light energy from the sun during the light reaction. Accessory pigments also in the plastids absorb other wavelength of light that chlorophyll does not absorb. These accessory pigments are responsible for other colors we see in plants such as yellow, orange and red. Chloroplasts are surrounded by a double membrane. Inside chloroplasts is a system of membranes arranged as stacks of flattened sacs called thylakoids. Each sac in the stack is called a granum. The thylakoids are surrounded by a solution called stroma. The dark reactions of photosynthesis take place in the stroma. Most chloroplasts are found in the leaves of plants. The underside of a leaf contains opening called stomata, where gases such as oxygen and carbon dioxide enter and leave. These openings of stomata are closed during the hottest times of the day by cells called guard cells.
