Everyone must do task 1 and 6, then you must choose 2 activities from tasks 25.
You must spend 8 hours on this project. You can spend more time if you want to.
Task One - Equations
Write the word equation for photosynthesis below (2 marks):
Write the balanced symbol equation (3 marks):
Task Two – Written Task
For each of the boxes in the diagram below, explain where each word comes
from, where it is found or what it is used for in the plant.
Use this information to write a description of how plants carry out
photosynthesis. It should be at least 1 side of A4.
Mark
Success Criteria
out of 5
1
State where the plant gets carbon dioxide and water from.
2
Describe how the plant uses oxygen and glucose.
3
Explain how and why glucose is stored in the plant.
4
Explain why plants need light and chlorophyll for photosynthesis.
5
Suggest what might happen to a plant if it could not get or use each
of these.
Task Three
We get many different products from plants. Make a presentation about these
products.
Make a list of products we get from plants. Try to make the list contain
different types of product (e.g. blueberries, sugar and paper).
What are the similarities and differences between all of these products?
What has to be done to some products to make them useable for us?

Success Criteria
out of 5
1
List products we get from plants.
2
State which we can use as they are and which need processing.
3
Describe the differences and similarities between the products in
your list.
4
Choose one material to explain how it must be processed before we
are able to use it.
5
Evaluate the usefulness of raw materials versus processed
materials.
Task Four
a) Draw diagrams to show what of gasses a plant takes in and out, and how
much during different times of the day. The size of the arrows should
represent how much of each gas is present.
HINT: Remember photosynthesis isn’t the only process to affect the amount of
carbon dioxide and oxygen. One picture has already been done for you.
b) Research the limiting factors for photosynthesis.
Mark
Success Criteria
out of 5
1
Draw arrows on the pictures correctly.
2
State factors which can affect the rate of photosynthesis.
3
Describe how the rate of photosynthesis changes at night compared
to during the day.
4
Explain what is meant by the term ‘limiting factor’.
5
Suggest ways in which the rate of reaction can be increased.
Task Five
Research two plants which have developed special ways to get water or carbon
dioxide in different habitats.
Make a poster to display these two plants.
Examples include:
-
Tundra Plants
Plants that grow in water
Cacti

3
Describe the way several plants have adapted to their habitats.

Task Six
You need to make a presentation to show the rest of your class what you have
been working on.
It can be on PowerPoint, but doesn’t have to be.
If you have made a poster and written an essay, you can show/talk about those.
Whether you use PowerPoint or not, you need to practice your presentation, so
you know exactly what you are going to say.
It should last between 2 and 3 minutes.
