Download Transpiration 1. Plants lose water through the stomata in their leaves

Photosynthesis, Respiration, Transpiration
Photosynthesis­
1. Sunlight hits the chloroplasts in the plant cells and starts a chemical reaction.
2. Plants take in water through their roots and carbon dioxide through the stomata on their leaves.
3. The water and carbon dioxide are combined, in the presence of light, to form sugar (glucose) and oxygen (a waste product.)

Respiration­
1. All living organisms must use oxygen to break down food for energy. This process is called respiration.
2. Plants take in oxygen from their stomata and combine it with the sugar they have made during photosynthesis. They break down the food for energy to grow.
Photosynthesis is sort of the opposite of respiration:
Photosynthesis (needs energy): carbon dioxide and water combine to make sugar and oxygen.
Respiration (produces energy): sugar and oxygen combine to make carbon dioxide and water.

Transpiration­
1. Plants lose water through the stomata in their leaves.
2. It can cause a plant to wilt or die.
3. Plants can control water loss by using the guard cells to close the stomata.
4. Remember: transpiration sounds like perspiration; I call transpiration “plant sweat.”
