Photosynthesis Review
1. Describe the energy transformation that occurs during photosynthesis.
SUN ENERGY IS TRANSFORMED INTO GLUCOSE AND OTHER SUGARS FOR THE PLANT
2. Write the BALANCED equation for photosynthesis, label the reactant and product side.
3. Life on Earth depends on photosynthesis for what two things?
GLUCOSE AND OXYGEN
4. How does a plant get the CO2 from the atmosphere?
PLANT TAKES IN THROUGH THE STOMATA
5. How is water transported through a plant?
XYLEM TISSUE IN THE ROOTS AND STEM TRANSPORT WATER FROM THE SOIL
6. How are carbohydrates transported through a plant?
PHLOEM TISSUE IN THE PLANT TRANSPORT CARBOHYDRATES THROUGH A PLANT
7. Distinguish between autotroph and heterotroph. Give an example of each.
AUTOTROPH MEANS “SELF ENERGY” – PLANTS AND ALGAE ARE EXAMPLES OF AUTOTROPHS
HETEROTROPH MEANS “OTHER ENERGY” – FUNGI AND ANIMALS ARE EXAMPLES OF HETEROTROPHS

Use the words below to fill in the blanks of the paragraph. Some words may be used more than once.
ENERGY ENTERS THE ECOSYSTEM IN THE FORM OF SUNGLIGHT. IN THE PROCESS OF PHOTOSYNTHESIS, PLANTS USE THE
LIGHT ENERGY TO PRODUCE GLUCOSE. THE SUN’S ENERGY IS STORED IN THE MOLECULE OF GLUCOSE. THE ENERGY
MOVES UP THE FOOD CHAIN WHEN A CONSUMER EATS THE PLANT. THE ENERGY OF GLUCOSE IS RELEASED BY ALL
LIVING THINGS DURING CELLULAR RESPIRATION. SOME OF THE ENERGY OF GLUCOSE IS USED TO DO THE WORK OF THE
CELL AND SOME OF THE ENERGY IS LOST TO THE SURROUNDINGS IN THE FORM OF HEAT.
