Photosynthesis - exam practice
Photosynthesis
Question 1 of 4
Plants are called producers because they make their own food from a process called photosynthesis.
Write the balanced symbol equation for photosynthesis.
Plants need energy to produce glucose.
Where do plants get this energy from?
Which part of a plant cell absorbs the energy needed for photosynthesis?
Explain why photosynthesis is considered an endothermic reaction.
Give two uses of the glucose produced in photosynthesis.
The diagram below represents a section of a leaf under the microscope, where photosynthesis takes place.
Identify and describe the role of two structures in the leaf that are involved in photosynthesis.
In a certain plant species, it is observed that the leaves have fewer stomata than a typical plant.
Suggest how this could impact the rate of photosynthesis.
The plant also has a very thick waxy cuticle.
Suggest the environment in which the plant lives and why having fewer stomata and a thick waxy cuticle is a useful adaptation.
The figure shows a cross-section of a plant leaf.
Describe the structure of the leaf and the functions of the tissues in the leaf.
Use the names of the tissues in your answer.
Complete the sentence about photosynthesis.
During photosynthesis, dioxide and are converted to glucose and .
The energy required for photosynthesis comes from the which is trapped by a green pigment called .
The plant can convert the glucose into which is insoluble and can be stored.
The rate of photosynthesis in a plant depends on several external factors.
These factors include light intensity and the availability of water.
Describe and explain the effects of two other factors that affect the rate of photosynthesis.
You should include one or more sketches of graphs in your answer.
