  • B3 1.8 Exchange in plants
    • Plants have stomata that allow them to obtain carbon dioxide from the atomosphere.
    • Carbon dioxide enters the leaf by diffusion. Leaves have a flat, thin shape and internal air spaces to increase the surface area available for diffusion.
    • Most of the water and mineral ions needed by a plant are absorbed by the root hair cell, which increase the surface area of the roots.
