Photosynthesis Function
To produce glucose
(food) for producers
The formula for glucose:
C6H12O6

Photosynthesis: How?Plants absorb sunlight energy, carbon
dioxide and water to make glucose

Structure: Chloroplast
Stroma: Fluid inside the chloroplast
Thylakoid: Group of pigments; absorb sunlight energy
Grana: Stack of Thylakoids

The giant sequoia tree is one of the largest trees on earth. It starts as a small seedling and grows into an enormous tree. Five children can stretch their arms across the width of the truck of one of the large sequoia trees! Where did most of the MATTER that makes up the wood and leaves of this huge tree originally come from? Circle the best answer.
• Sunlight• Water• Soil• Carbon dioxide• Oxygen• Minerals• Chlorophyll
Explain your thinking. How did you decide where most of the matter that makes up this tree came from?

would know the answer to this

1. Carbon dioxide is released by consumers and producers
2. Producers absorb carbon dioxide; break off the carbon; and release oxygen.3. Process continues until six carbons are collected
4. The six carbons, the stored energy from the sun, hydrogen, and oxygen ALL combine together to make Glucose C6H12O6
C6H12O6

Why are 6 carbon dioxide molecules absorbed?
Need 6 carbons from carbon dioxide to make:
