Model Activity Task : Class IX: Life Science -(Part 31
1. Mention the role of water in photosynthesis. Explain the role of photosynthesis in maintaining
the balance of O2 and CO2 in the environment.
2 How does temperature influence evaporation Evaporation is said
Answers
Answer:Water is one of the reactants in photosynthesis, it provides the hydrogen needed to form glucose (a hydrocarbon). Water and carbon dioxide enter the leaf through the stomata (small holes on the underside of the leaf that are controlled by gaurd cells) by diffusion.
Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. These carbohydrates store energy. Oxygen (O2) is a byproduct that is released into the atmosphere. This process is known as photosynthesis.
Evaporation rates are higher at higher temperatures because as temperature increases, the amount of energy necessary for evaporation decreases. ... Humidity, or water vapor content of the air, also has an effect on evaporation. The lower the relative humidity, the drier the air, and the higher the evaporation rate.
