The three main processes in plant physiology are photosynthesis, respiration, and transpiration. Photosynthesis allows plants to produce their own food (carbohydrates) from carbon dioxide, water, and sunlight using chlorophyll in their leaves. Respiration breaks down carbohydrates to release energy, which is used for growth and tissue building. Transpiration is the process by which plants lose water, primarily through their leaves, which serves purposes like mineral transport and cooling the plant.

2. Respiration

3. Transpiration

4. Photosynthesis A plants ability to manufacture its own food (energy)

5. a plant requires: energy from sunlight,

6. carbon dioxide from the air

7. water from the soil

8. Photosynthesis The only cells that can carry out photosynthesis are in the mesophyll layer of leaves and stems
