Question

What is the effect of excess of oxyygen on the rate of photosynthesis?

Answer 1

Answer:

The inhibition increases with oxygen concentration and is about 30% in an atmosphere of 21% O2 and 0.03% CO2. Undoubtedly, therefore, oxygen in normal air exerts a strong inhibitory effect on photosynthetic CO2 fixation of land plants under natural conditions.

Answer 2

Dear Student,

● Photosynthesis -

• It is a process used by plants and other organisms to convert light energy into chemical energy.
• In photosynthesis plants take CO2 & water, convert it into glucose & O2 in presence of sunlight.

CO2 + H2O + sunlight → C6H12O6 + O2

◆ Effect of excess of oxygen on the rate of photosynthesis -

• Oxygen is a product in the process of photosynthesis.
• Rate of photosynthesis is inversely proportional to
• oxygen concentration.
• Excess of oxygen has inhibitary effect on rate of photosynthesis.

Thanks dear. Hope this helps you ..
