Draw a labelled diagram to show the arrangement of the vascular tissues in a dicotyledonous (dicot) root. - Leaving Cert Agricultural Science - Question d - 2020

To effectively illustrate the vascular tissues in a dicot root, follow these steps:

1. Start with the Outline of the Root: Begin by drawing an elongated cylindrical shape to represent the root.

2. Draw the Vascular Cylinder: Inside the root, draw a central area to represent the vascular cylinder or stele. This should appear circular and is an important part of the diagram.

3. Add Xylem and Phloem:

   • Inside the vascular cylinder, draw the xylem which typically appears in a star shape or is arranged in several arms.
   • Add the phloem, which lies between the xylem arms. Typically, the arrangement shows alternate xylem and phloem to ensure efficient transport.

4. Label the Components: Clearly label the xylem, phloem, and vascular cylinder (stele) in your diagram.

5. Ensure Clarity and Neatness: Ensure your drawing is clear, with straight lines and legible labels to fulfill the requirement of being a labelled diagram.
