Plants carry on two complementary processes, photosynthesis and respiration. How do the two processes differ? Photosynthesis creates sugar, and respiration breaks sugar down.

Photosynthesis requires oxygen, and respiration requires carbon dioxide.

Photosynthesis takes place only during the day, and respiration takes place only at night.

Photosynthesis takes place in all plant cells, and respiration takes place only in leaf cells.
