what will happen to the process of photosynthesis when a plant is kept in sunlight, dark, absence of co2?

i want to know answers for my project

Kept in:
1.  Sunlight:  Assuming all other factors are optimal, the plant will produce oxygen and organic molecules rapidly.
2.  Dark:  Photosynthesis would not occur.  The plant would use cellular respiration and oxygen to produce energy from organic molecules present in the cells
3.  Absence of Carbon Dioxide:   Photosynthesis might occur slowly as carbon dioxide is being released from cellular respiration if all other factors are optimal.  If no carbon dioxide is available, plant would have to revert to cellular respiration to produce energy needed for cellular metabolism.
