• Absorbs sunlight for photosynthesis

Which of the following is a characteristic of fibrous roots?

• One thick, tapered root

• Grow in dry areas with inadequate soils

• Adventitious roots that grow above the ground

• Many small roots from seed base

What is the function of the root cap?

What is the function of root nodules in certain plants?

• Absorb water and nutrients

• Store extra starch and sugars

• Prevent soil erosion

• Produce enzymes to make atmospheric nitrogen available to plants

What is the primary role of root hairs?
