1. NOTES PHOTOSYNTHESIS, RESPIRATION, AND TRANSPIRATION

2. PHOTOSYNTHESIS Process plants use to make food (sugar/glucose)
Occurs in chloroplasts of plant cells
Chlorophyll (green pigment) must be present
Takes place during daytime (sunlight)
Equation:
sunlight
Carbon dioxide + water  glucose + oxygen
chlorophyll

3. RESPIRATION Process where energy is released inside plant cells for…
Building new cells
Repairing cells
Takes place in mitochondria of cell
Occurs day and night
Equation:
Glucose + oxygen  carbon dioxide water + energy

4. TRANSPIRATION Process by which water is lost by plants
Water passes out through stomata (openings in leaf through which gases enter and leave)
Plant loses about 99% of water that enters (only 1% used in photosynthesis)
Results of transpiration
Leaves are cooled
Can increase humidity
Creates upward motion of water from roots through stem to leaves out stomata
