Which of the following correctly compares and contrasts the function of the roots and the stems of a plant?

The correct answer would be:

Roots:
- Function: Anchor the plant to the ground, absorb water and nutrients from the soil, store food reserves
- Structure: Typically underground, have a branching network of root hairs for increased surface area for absorption, may have root nodules that harbor nitrogen-fixing bacteria

Stems:
- Function: Support the leaves, flowers, and fruits of the plant, transport water and nutrients between the roots and the leaves, and may store food reserves
- Structure: Typically above ground, have nodes and internodes, may have leaves and buds attached, contain vascular tissues (xylem and phloem) for nutrient exchange.
