Ward's® Plasmolysis in Plant Cells Lab Activity

Observe Dramatic Effect of Water Loss on Onion Cells.

What makes a plant wilt when it needs water, and “come back to life” when it receives that water? Find out with this simple investigation. Using only an onion you supply and this kit’s materials, students can easily see the effect of varying osmotic conditions on plant cells, and learn the importance of water to a plant’s structure. It includes enough materials for six setups, a teacher’s guide, and student copymaster.

The kit is also available for purchase with a link to a NewPath digital lesson, which includes a variety of resources on the topic, including background information, illustrations and self-assessments.
