Plant System

Plant roots have extensions called root hairs. These root hairs are important in the homeostasis of the plant. Which statement best explains the importance of the root hairs to the stems and leaves of the plant?

• root hairs convert minerals into glucose for immediate use by cells

• root hairs decrease the need for osmosis and diffusion in vascular tissue

• root hairs prevent water loss in leaves through transpiration and gas exchange

• root hairs increase the surface area of the roots for nutrient and water absorption
