Photosynthesis
Biology

2. Photosynthesis Used by plants to generate energy
Use energy from sun to make sugar (glucose)

3. Photosynthesis Begins at the leaf within the chloroplast
Chlorophyll is the molecule in the chloroplast

4. Reactants to Photosynthesis
Radiant energy (sunlight) + 6 molecules of carbon dioxide + 6 molecules of water
Water enters plant through roots and travels to leaves
Carbon dioxide and sun enter into leaf.

5. Products of Photosynthesis
1 molecule of sugar (glucose) + 6 molecules of oxygen
Glucose leaves the leaf and provides energy for the plant.

6. Two stages of photosynthesis
Light-dependent reactions require sunlight and happen in the thylakoid
Light-dependent reaction makes ATP and oxygen.
Light-independent reactions do NOT require sunlight and happen in the stroma (Calvin cycle).
ATP with carbon dioxide is used to create glucose.

7. ATP Universal fuel for all cells
Transports needed substances across membranes
Activates metabolic reactions that would not occur automatically
Performs specific mechanical work, like moving muscles.

8. Glucose
Glucose provides energy for the plant and for animals that eat the plants.
