Read the following statements and choose the following option: 1. Internal CO2 concentration does not affect rate of photosynthesis 2. External plant factors do not affect rate of photosynthesis 3. some greenhouse crops such as tomatoes and bell pepper. 4. The dark reactions being enzymatic are temperature controlled.

Options

  1. AOnly 3 is incorrect
  2. BOnly 2 is correct
  3. CBoth 2 and 4 are correct
  4. DBoth 1 and 2 is incorrect

Correct answer

D. Both 1 and 2 is incorrect

Step-by-step solution

Photosynthesis is under the influence of several factors, both internal (plant) and external. The plant factors include the number, size, age and orientation of leaves, mesophyll cells and chloroplasts, internal CO2 concentration and the amount of chlorophyll.
