While having lessons of biology in school, Rohit listened carefully to his teacher Mrs Kavita, explaining how do plants grow, develop and prepare their own food by photosynthesis. She also explained them that they themselves can observe this by growing a plant at home. Rohit too, out of curiosity potted a plant in his room but after a week or two, he observed that leaves of plant became yellow and finally they started wilting.
He asked his biology teacher about this and she told him that light is necessary for photosynthesis to occur.
(a)Give an overall equation for photosynthesis showing its requirements as well as products formed.
(b)What role do light play in the process of photosynthesis?
(c)Name other factors that influence the rate of photosynthesis.
(d)What values are observed from Rohit’s characte

Answer:
- The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the product
- The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
- Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
