Why do some root cells have root hairs?
Correct answer: B. To increase the surface area of the cells
- A. For the maintenance of the temperature of the cell sap
- B. To increase the surface area of the cells
- C. To increase the volume of the cell sap
- D. To provide a place for cell nuclei
- E. To allow movement of soil particles
Explanation
Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water.
