Which of the following contribute to the surface area available for water absorption from the soil by a plant root system?
I.root hairs
II.endodermis
III.mycorrhizae
IV.fibrous arrangement of the roots

Question

Quizplus · Accepted Answer

Root hairs, mycorrhizae, and a fibrous arrangement of roots all increase the surface area for water absorption. Root hairs extend the root surface, mycorrhizae are symbiotic fungi that enhance nutrient and water uptake, and a fibrous root system increases the root surface area. The endodermis does not contribute to surface area but regulates water and nutrient flow into the plant.
