Verified step by step guidance1
Understand the function of each plant part listed: leaves, flower petals, stem cortex, and root hairs on roots.
Recall that leaves primarily perform photosynthesis and gas exchange through stomata, not water absorption from soil.
Recognize that flower petals are involved in reproduction and attracting pollinators, not water uptake.
Know that the stem cortex mainly provides support and storage, but does not absorb water directly from the soil.
Identify that root hairs, which are extensions of root epidermal cells, increase surface area and are specialized for absorbing water and minerals from the soil.
