1. Where am I going?
• The following are all transported around the
plant where do they start off and where do
they end?
Glucose
Water
Mg ions
Nitrates
What are they needed for?

2. Transport systems in plants
Lesson objectives
• All will be able to name the transport systems
in plants
• Most will be able to describe the materials
which are moved in the transport systems
• Some will be able to explain the importance of
the transport systems in plant

3. Transport systems in plants
• There are two main transport systems in a
plant:
– xylem
– phloem

4. Transport systems in plants
• Xylem
– Transports water and
mineral ions
– Dead cells
– Long hollow tube like
vessels

5. Transport systems in plants
• Phloem
– Transports sugars
– Living cells
– Sugar then used for…

6. Transport systems in plants
• Cut thin slices of celery and
look at the xylem cells
• Use the microscopes to look
at leaf cross sections
• Carefully draw the vascular
bundle
• Label the xylem and phloem
• Annotate with function

7. Transport systems in plants
• Look where the tree has its phloem and xylem
– why to tress often die when they are
gnawed by animals?

8. 1. What makes active transport different to diffusion?
2. What is the formula for glucose?
3. How does a plant leaf maximise diffusion?
4. How does a plant leaf maximise surface area?
5. Where does photosynthesis take place?
6. Which transport system transports sugar?
7. Where is glucose made in a plant?
8. What conditions increase transpiration rates?
9. Which transport mechanism results in movement of water from the soil into the roots?
10. What starts the process off transpiration in a plant?
