In most vascular plants, which structure is primarily responsible for absorbing water and dissolved minerals from the soil?
A
Stomata on the leaves
B
Xylem vessels in the stem
C
Root hairs on young roots
D
Flower petals
Verified step by step guidance1
Identify the function described in the question: absorbing water and dissolved minerals from the soil.
Recall the main structures of vascular plants involved in water and mineral transport: stomata, xylem vessels, root hairs, and flower petals.
Understand that stomata on leaves primarily regulate gas exchange and water vapor release, not absorption from soil.
Recognize that xylem vessels transport water and minerals upward but do not absorb them directly from the soil.
Know that root hairs on young roots increase surface area for absorption, making them the primary structures responsible for taking up water and dissolved minerals from the soil.
