Wake-up
1. What is the role of pigments in
photosynthesis?
1. Where can they be found?
1. Write the summative equation for
photosynthesis using words.
Photosynthesis II
Christopherson
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
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.
