1 Monocotyledon and diocotyledon

2 Learning outcomes Differentiate between monocotyledon and diocotyledon
Use a microscope to Identify and compare woody and non woody stems Distinguish the root cap and describe its functions

3 activity In your group examine the leaves and arrange them into monocotyledon and diocotyledon

4 monocotyledon The name is derived from the fact they have one seed leaf within their seed (a cotyledon is a leaf) Narrow, strap like leaves within parallel veins

5 Narrow, strap like leaves within parallel veins

6 activity Now look at your arranged leaves using the magnifying glass and assess to see if you made the correct answer

7 Fibrous roots

8 Scattered vascular bundles

9 activity In your groups using the microscopes identify the scattered vascular bundles

10 Primarily wind pollinated little secondary growth and no woody growth

11 dicotyledon Dicots have two seed leaves within their seed
These are the most common flowering plants and include most trees and shrubs

12 Broad leaves within a network of veins

13 Tap root

14 Vascular bundles arranged in a ring around stem or root

15 activity In your groups using the microscopes identify the arranged vascular bundles

16 Primarily insect pollinated

17 Secondary growth forming wood

18 activity In your groups Examine and locate the named parts of the secondary growth forming wood

19 Root cap The root cap is a layer of cells on the surface of the root tip that protects the tip as it grows and pushes through the soil. The cells can be destroyed by this but they are replaced by new ones.

21 activity In your groups using the microscope identify the fibrous and tap roots Locate the root cap

22 Activity From what you have learnt in todays lesson apply your knowledge and test another member of a different group.
