Question

photosynthesis involves chemical reactions in which carbon dioxide and water are converted into sugar. energy for cell activities is stored in sugar. oxygen gas is a by - product of this reaction. in addition to light, photosynthesis needs chlorophyll and enzymes (organic catalysts) which aid the reaction. enzymes are necessary for all cell reactions. the word equation for photosynthesis is: carbon dioxide + water $xrightarrow\text{chlorophyll}{\text{enzymes and light}}$ sugar + oxygen + water this equation tells you that the plant combines carbon dioxide and water in the presence of enzymes, light, and chlorophyll to produce sugar (food), oxygen, and water. the sugar is used by the organism as a source of energy and the oxygen is used for its respiration. excess oxygen is released into the air and is used by animals for respiration. water is released into the environment. review questions 1. what is the function of the chloroplast? 2. the green pigment in chloroplasts is called 3. why arent algae classified as plants? 4. photosynthesis is the process by which 5. the energy source for photosynthesis is 6. write the word equation for photosynthesis. 7. why do scientists use chromatography? m. centrioles. these structures are found mainly in animal cells. they look like cylinders and are located in pairs near the nucleus. centrioles are involved in cell division. review questions 1. the centrioles are in shape and are located near the in cells. they are involved in the process of

Explanation:

1. Chloroplasts are the site of photosynthesis in plant cells, converting light - energy into chemical - energy.
2. Chlorophyll is the green pigment in chloroplasts that absorbs light for photosynthesis.
3. Algae lack true roots, stems, and leaves which are characteristic of plants.
4. Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into sugar and oxygen using light - energy.
5. The energy source for photosynthesis is light.
6. CARBON DIOXIDE + WATER $\xrightarrow[\text{chlorophyll}]{\text{enzymes and light}}$ SUGAR + OXYGEN + WATER
7. Chromatography is used by scientists to separate mixtures into their components.

For centrioles:

1. Centrioles are cylindrical in shape and are located near the nucleus in animal cells. They are involved in the process of cell division.
