Cambridge Secondary (7-9). Stage 9. Science. Learner's Book - Unit 4: Maintaining life - Question 4

Annotating a diagram. Work with a partner, or in a group of three. On a large sheet of paper, make a big copy of the unlabelled, circular diagram showing the position of xylem vessels in a root. Make sure that you leave enough space around your drawing to add some writing. Use information on the three-dimensional diagram and in the text below to add annotations. The annotations should describe what each part does, so that someone looking at your diagram can understand how water is absorbed by the root, and how it is transported upwards from the root.

Information: root hairs absorb water and mineral ions; water moves from the outside of the root towards its centre and enters the xylem vessels. These form long hollow tubes that carry water up the plant.
