Lesson Worksheet: Photosynthesis Biology

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

Q1:

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

  • AChlorophene
  • BChromatin
  • CChlorophyll
  • DChlorine

Q2:

What gas is a reactant in photosynthesis?

  • AOxygen
  • BCarbon oxide
  • CCarbon dioxide
  • DSulfur dioxide

Q3:

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

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

Q4:

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

Q5:

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

Q6:

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

Q7:

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

Q8:

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

Q9:

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.

Q10:

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

What type of chemical reaction is this?

  • AExothermic
  • BEndothermic
