Lesson Worksheet: Photosynthesis Biology

In this worksheet, we will practice describing the process of photosynthesis and explaining the importance of the products made.


What is the green pigment contained within a chloroplast to absorb sunlight?

  • AChlorophene
  • BChromatin
  • CChlorophyll
  • DChlorine


What gas is a reactant in photosynthesis?

  • AOxygen
  • BCarbon oxide
  • CCarbon dioxide
  • DSulfur dioxide


Which of the following is the correct, balanced symbol equation for photosynthesis?

  • A6CO+CHO6HO+6O2612622
  • BCHO+6O6CO+6HO6126222
  • C6CO+6HOCHO+6O2261262
  • D6O+6HOCHO+6CO2261262


Plants use the glucose produced by photosynthesis in many ways.

In what biological process can the plants break glucose down to provide energy?

  • ARespiration
  • BReplication
  • CPhotosynthesis
  • DSynthesis
  • EMitosis


A plant requires energy for photosynthesis to occur.

Where does this energy come from?

  • AThe absorption of mineral ions from the soil
  • BArtificial or natural light
  • CHeat energy
  • DBackground radiation


In plants, the glucose produced in photosynthesis can be converted into cellulose.

What subcellular structure in plants is cellulose used to make?

  • ACytoplasm
  • BCell membrane
  • CCell wall
  • DChlorophyll
  • ENucleus


Which of the following terms refers to organisms in the food chain that can photosynthesize to produce their own food?

  • ASecondary consumers
  • BPrimary consumers
  • CDetritivores
  • DProducers
  • EDecomposers


The glucose made in photosynthesis can be converted into multiple molecules for the plant. Which of the following is not a molecule that can be synthesized with the use of glucose?

  • AAmino acids
  • BStarch
  • CLipids
  • DCellulose
  • EChlorophyll


Which of the following does not represent an adaptation of leaves for photosynthesis?

  • ALeaves have a large surface area to maximize the amount of sunlight they can take in.
  • BLeaves have hair cells that extend outward to increase the surface area for water uptake.
  • CLeaves have openings called stomata on their undersides that open to allow CO2 in.
  • DLeaves are thin, so diffusion pathways for gases are very short.
  • EPalisade cells in the leaves contain many chloroplasts to maximize photosynthesis.


For photosynthesis to occur, energy has to be taken in from the surroundings.

What type of chemical reaction is this?

  • AExothermic
  • BEndothermic
