3) The anatomy of a chloroplast
This entry exercise concerns photosynthesis. As you read the points you can check them off.
Photosynthesis is the process by which green plants (producers) capture light energy and transform carbon dioxide and water into chemical energy.
Plants draw water (H2O), typically through a root system, collect carbon dioxide (CO2) from the atmosphere, and using light energy collected from the sun, biochemically convert the H2O and CO2 into oxygen (O2) and glucose (C6H12O6).
The biochemical reaction of photosynthesis requires light energy as carbon dioxide and water do not spontaneously transform into glucose and oxygen. This is called the energy of activation or activation energy.
Photosynthesis is a series of chemical reactions that convert light energy into chemical energy. It is an endothermic reaction because it requires energy (solar energy).
Photosynthesis can be expressed as the following chemical equation:
CO2. + H2O + energy ---> O2 + C6H12O6
Photosynthesis can be expressed as the following word equation:
carbon dioxide + water + light energy ---> oxygen + carbohydrates (glucose)
Chloroplasts within the leaves of plants contain chlorophyll (chlorophyll a and chlorophyll b) that absorbs light for use in photosynthesis.
