Solve this multiple-choice question and choose the correct option.

Plant water uptake: Identify the structures through which plants absorb most of the water they need. Full question: Plants absorb the major part of their water requirement primarily through which root structures? Choose the correct option.

Difficulty: Easy

Root hairs
Stomata
Leaves (cuticle)
Stem epidermis
Flower tissues

Correct Answer: Root hairs

Explanation:

ConceptRoot hairs dramatically increase absorptive surface area and are the principal sites for water and mineral uptake from the soil solution.

Why others are incorrectStomata regulate gas exchange and transpiration; stems/leaves are not the main water-absorbing organs.

Final AnswerRoot hairs.
