Photosynthesis (LS5) Study Guide
Name:___________________________
Directions: Give a short definition for each (not copied from notes) and use key words. 1. Photosynthesis – ____
process by which a plant cell captures
energy in sunlight and uses it to make food________ 2. Respiration – ____
process by which animal cells obtain energy
and releasing stored energy______ 3. Chloroplast – ______
Inside the cell. The location of
photosynthesis takes place._____ 4. Chlorophyll – ___
The reason for why a plant is green and it’s
located in the chloroplast and captures sunlight____ 5. Producers – __ 6. Glucose – __
Organism that can make its own food___
A simple sugar that is an important energy
source___ Directions: Answer the following questions 7. Name the three places plants store energy?
a. Roots b. Stem c. Leaves d. Seeds 8. Plants use the gas, __
Carbon Dioxide__ to start photosynthesis.
Chloroplast_____.
9. Photosynthesis takes place in the organelle, ____ 10. __
Chlorophyll___ in the chloroplast allows photosynthesis to occur.
11. Plants get their green color from ____
Chlorophyll____.
12. Plants take light energy and convert it to __
Chemical___ energy.
13. What are the products of photosynthesis? ____
oxygen and glucose (sugar)______
14. Explain why leaves change color in the fall (why trees decide to do it, and why the leaves look a different color to us).
When days get shorter and it gets colder, the chlorophyll in the leaves break down. Which is when different colors reveal themselves because chlorophyll is what gives leaves it’s green color. The trees are preparing for winter. ____ 15. Give two reasons plants are important to animals ___
depend on oxygen and to supply our food to obtain
energy________ 16. Write the equation for photosynthesis
17. Use the word bank to fill-in-the-blanks in the photosynthesis and cellular respiration diagram below: Word Bank:
Mitochondria Water (H2O)
Chloroplast
Oxygen (O2)
Glucose sugar (C6H12O6)
