Frequently Asked Questions
Why are root hairs only found on the epidermis of roots?
Root hairs are epidermal extensions that maximize surface area for water and mineral absorption. They are thin-walled to allow rapid diffusion. They are in the epidermis because that is the interface between the soil and the plant.
How do guard cells control stomatal opening?
Guard cells are specialized epidermal cells with thick inner walls. When they absorb water, they swell and the thin outer wall curves outward, opening the stoma. When they lose water, they collapse, closing the stoma. This controls water loss and gas exchange.
What is the purpose of the endodermis in roots?
The endodermis is a specialized layer in roots with a waterproof strip called the Casparian strip. This forces all water to move through the living endoderm cells rather than around them, allowing the plant to regulate water uptake.
