Make a prediction: Where do you think that all of the mass
from a full grown tree comes from?
a) air
c) water
b) soil
d) carbon dioxide
Make a prediction: What color of light do you think that
plants absorb and reflect?
What are the products and reactants in
the photosynthesis reaction shown
above?
What reactant is missing in this chemical
reaction?
As you watch the following video on the
photosynthesis process pay attention to the following
points:
 What are the stages of photosynthesis?
How is the sun’s energy used during photosynthesis?
What types of energy is released as a product in the
photosynthesis process?
How plants use the sugar they produce?
What do you notice
about this diagram of
light energy being
converted into chemical
energy in a plant cell?
-Which organelle does
light energy enter?
- What area of this
organelle does light first
react?
-What are the products of this
reaction?
-What is the 2nd phase of this
reaction called?
-What are the reactants of the
2nd phase?
-What are the products of the
2nd phase?
