In this worksheet, we will practice describing the process of photosynthesis, and explaining the importance of the products made.
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?
- BCell membrane
- CCell wall
What is the green pigment contained within a chloroplast to absorb sunlight?
Plants use the glucose produced by photosynthesis in many ways.
In what biological process can the plants break glucose down to provide energy?
What gas is a reactant in photosynthesis?
- BCarbon oxide
- CCarbon dioxide
- DSulfur dioxide
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
For photosynthesis to occur, energy has to be taken in from the surroundings.
What type of chemical reaction is this?
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 in.
- DLeaves are thin, so diffusion pathways for gases are very short.
- EPalisade cells in the leaves contain many chloroplasts to maximize photosynthesis.
How do plants obtain the carbon dioxide required for photosynthesis?
- AIt is actively transported from the soil into the root and moved up the plant to the leaves.
- BIt diffuses from the soil into the stem and is transported up to the flowers.
- CIt diffuses from the surrounding air into the plant through open stomata.
- DIt is moved from the soil into the root by osmosis and transported up the plant to the leaves.
Which of the following terms refers to organisms in the food chain that can photosynthesize to produce their own food?
- ASecondary consumers
- BPrimary consumers
Which of the following is the correct, balanced symbol equation for photosynthesis?
When it is not required by the plant, glucose can be converted into different molecules for storage. What is the main molecule glucose is converted into for storage in plants?
- CAmino acids
How do plants obtain the majority of the water they require for photosynthesis?
- AIt diffuses from the soil to the stem and is transported up to the flowers.
- BIt is moved from the soil to the root by osmosis and transported up the plant to the leaves.
- CIt diffuses from the surrounding air into the plant through the open stomata.
- DIt is actively transported from the soil to the root and moved up the plant to the leaves.
The diagram shows part of the word equation for photosynthesis.
Complete the equation with the correct reactants and products.
- A(Carbon dioxide + glucose) (water + oxygen)
- B(Fatty acids + oxygen) (carbon dioxide + lipids)
- C(Oxygen + water) (sucrose + carbon dioxide)
- D(Carbon dioxide + water) (oxygen + glucose)
The diagram shows the basic structure of a palisade cell.
What letter represents the organelle in which photosynthesis occurs?
What is this organelle called?
- BCell wall
The given diagram shows a set of guard cells surrounding a stoma when it is open and when it is closed.
Fill in the blanks: Stomata will close at night because there is no light, so cannot occur and is not required.
- Aphotosynthesis, oxygen
- Bphotosynthesis, carbon dioxide
- Crespiration, carbon dioxide
- Drespiration, oxygen
