Why do plants need roots?
Description
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.
Classroom Ideas
When labelling parts of the plant, this clip can help to expand children鈥檚 understanding of the function of roots. Children may investigate roots further by growing broad beans in transparent plastic bottles. This will illustrate how the roots spread out to anchor the plant and collect water.
