1 Cells

Continued

1 In a group of two or three, use the materials to build a picture of a plant cell.
It is up to your group to decide exactly how to use the materials to make your

picture. You may not want to use all of the materials.
2 Ask your teacher, or other people in your class, to check that you have put all
the right pieces in the right places.
3 Now remove some of the pieces, to change your picture into an animal cell.

Self assessment

Compare your picture with the pictures made by other groups.
What differences are there between them?
Now that you have seen the other pictures, is there anything you would like to change
in yours?

• What have you done that helps you to remember the differences between

animal cells and plant cells?
• Do you think that you can always decide whether a picture shows an animal
cell or a plant cell? What is the most important feature to look for?
