Detailed explanation-1: -photosynthesis in plants is Freezing temperature. energy from the Sun to form glucose and oxygen. rainfall and increased carbondioxide levels will increase glucose production except Freezing temperature.
Detailed explanation-2: -Atmospheric carbon dioxide has no affect on the rate of photosynthesis.
Detailed explanation-3: -Low temperature depresses the rate of photosynthesis both directly and indirectly, either by influencing the activity of photosynthetic enzymes involved in the Calvin cycle, such as Rubisco (Yamori et al., 2010), or by reducing stomatal conductance (Allen et al., 2002).
Detailed explanation-4: -Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
Detailed explanation-5: -The total amount of glucose production due to photosynthesis can be increased in two ways: Increasing the intensity (brightness) of the light that illuminates the plant leaves. Increasing the brightness of light can increase glucose production up to a certain point.
