1) Photosynthesis – oxygen is formed and carbon dioxide is bound, which was formed during breathing, organic matter is formed, energy is stored.
2) Breathing – carbon dioxide is formed for photosynthesis and oxygen is consumed, organic substances are oxidized.
3) When breathing, plants oxidize the glucose obtained by photosynthesis and obtain energy from them. Energy is needed for the synthesis of enzymes, including photosynthesis enzymes.
