Phytochrome is a blue-green pigment or a photoreceptor present in plants. These pigments regulate several light-dependent developmental processes in plants, such as the germination of seeds, the timing of flowering, and elongation of seedlings. Phytochrome is expressed in most of the plant tissues.

A) The concentration of CO2 is lower inside a plant cell than in the atmosphere (outside the cell). In your own words, describe how the CO2 levels are kept low inside the plant cell and explain why this is necessary. Assume stomata are open. B) Regarding the situation presented in Part A and assuming that the stomata of the plant leaves are closed, would this favour the induction of photorespiration in a C3 plant? Explain. Make reference to relevant molecule or molecules as needed. Please clearly label your responses as A and B
