What is photosynthesis?
The process where green plants use sunlight to make glucose and oxygen from carbon dioxide and water.
What does chlorophyll absorb to enable photosynthesis?
Sunlight energy.
What is the role of chlorophyll in photosynthesis?
Chlorophyll absorbs solar energy.
What happens to carbon dioxide during photosynthesis?
Carbon dioxide is reduced to form glucose.
Photosynthesis Inputs
Carbon dioxide, water, sunlight
Photosynthesis Products
Glucose and oxygen
Photosynthesis Sequence Step 1
Absorb sunlight energy
Respiration ATP yield (aerobic)
38 ATP
Respiration ATP yield (anaerobic)
2 ATP
Photosynthesis vs Respiration
Photosynthesis builds glucose; respiration breaks it down.
Glucose pathways
Stored as starch, transported as sucrose, or used in respiration.
