Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the fuel used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive.
Project Ideas:
- Create a diagram showing photosynthesis in a plant.
- Explain the cycle of photosynthesis. Chart it. Define the terms.
- Grow four of the same plants. Limit the amount of sunlight on two of the plants. Measure their height and fullness daily. Are the plants with limited sunlight different? How?
