Detailed explanation-1: -Carbon dioxide-An increase in carbon dioxide concentration can speed up photosynthesis. The rate of photosynthesis is affected by the intensity and quality of light.
Detailed explanation-2: -The concentration of dissolved sugars in the phloem sap will be affected by: The rate of photosynthesis (which is affected by light intensity, CO2 concentration, temperature, etc.) The rate of cellular respiration (this may be affected by any factor which physically stresses the plant)
Detailed explanation-3: -The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Detailed explanation-4: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Detailed explanation-5: -The presence of sugar in the medium diminishes the need for sugar production and therefore should result in lower photosynthesis.
