Monocotyledon and diocotyledon

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

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

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

Narrow, strap like leaves within parallel veins

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

Fibrous roots

Scattered vascular bundles

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

Primarily wind pollinated little secondary growth and no woody growth

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

Broad leaves within a network of veins

Tap root

Vascular bundles arranged in a ring around stem or root

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

Primarily insect pollinated

Secondary growth forming wood

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

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.

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

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