A. What is photosynthesis?B. What are the two
root words and what do these root words mean?

• A. The process through which plants make food.
• B. Photo means light and synthesis means
  putting together.

2. What do scientists call the colors seen
through a prism?

• The visible spectrum.

4
3. What do pigments do?

• Absorb different colors of light.

5
4. What pigment is most abundant in plants?

• chlorophyll

6
5. Where is chlorophyll found?

• Chlorophyll is found in the microscopic plant
  structures called chloroplasts.

7
6. What does chlorophyll absorb?

• Chlorophyll absorbs most blue light and red
  light.

7. During the first stage of photosynthesis,
what do plants capture?

• Plants capture radiant energy in white light.

9
8. What part of the plant absorbs most of the
energy?

• In plants, the process of capturing energy
  occurs mainly in the leaves and other green parts
  of the plant.

10
9. Describe the second stage of photosynthesis.

• Captured energy is used to produce sugar. The
  plant needs two raw materials for this stage
  water and carbon dioxide.

11
10. What powers the complex chemical reactions
that take place inside the chloroplasts?

• The reactions are powered by the radiant energy
  that was captured during the first stage of
  photosynthesis.

11. What is the chemical equation scientists use
to sum up what occurs during photosynthesis?
