In most vascular plants, which structure is primarily responsible for absorbing water from the soil?
A
Flowers (petals and sepals)
B
Stomata on leaves
C
Xylem vessels in the stem
D
Root hairs on young roots
Verified step by step guidance1
Understand the function of each plant structure listed: Flowers (petals and sepals) are mainly involved in reproduction, not water absorption.
Recognize that stomata on leaves primarily regulate gas exchange and water vapor release, rather than absorbing water.
Know that xylem vessels in the stem transport water throughout the plant but do not absorb water directly from the soil.
Identify root hairs on young roots as extensions of root epidermal cells that increase surface area for efficient water absorption from the soil.
Conclude that root hairs on young roots are the primary structures responsible for absorbing water from the soil in most vascular plants.
