Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these will not affect photosynthesis?
A
Light
B
Temperature
C
Glucose Availability
D
Carbon Dioxide
Explanation: 

Detailed explanation-1: -The absence of oxygen will have no effect on the process of photosynthesis. This is because the photosynthetic process utilises water and carbon dioxide to produce oxygen and carbohydrate in the presence of chlorophyll and sunlight.

Detailed explanation-2: -During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-3: -Carbon dioxide (CO2) is a product of respiration and not photosynthesis. The CO2 released in the air is then absorbed or fixed by plants during photosynthesis. Hence this option is correct.

Detailed explanation-4: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Detailed explanation-5: -Answer: The chlorophyll content of leaves, the accumulation of by-products, the internal structure of leaves, light intensity, carbon dioxide concentration, and temperature are the six factors influencing the rate of photosynthesis.
