An explanation of why roots are important to a plant. An ecologist, Dawn, shows a pot plant with restricted room for its roots, which are all knotted together. Dawn explains how roots anchor a plant in the soil and also seek out water to bring up to the stem. She explains how the stem acts like our skeleton and supports the plant.

Growing the same plants in different sized containers will allow pupils to investigate and measure how space for roots may affect plant growth. Pupils may also be challenged to match different plant roots images with their habitats. This will enable children to see how plant roots are adapted to different conditions. Other activities could involve demonstrating how to re-pot plants into larger containers and taking care of delicate roots. Pupils may also look at roots and root hairs under microscopes to understand their function further.
