C

D
Roots absorb water and nutrients for a plant, while stems transport water and nutrients throughout a plant
Explanation: 

Detailed explanation-1: -Stems are the parts of plants that bear branches, leaves, and fruits. Roots are the underground parts of plants that bear root hairs. Their primary function is to supply minerals, water, and food to all plant parts.

Detailed explanation-2: -Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells. They move water.

Detailed explanation-3: -The water is absorbed by the root hair and undergoes cell to cell movement by osmosis until it reaches the xylem. This water is then transported through the xylem vessels to the leaves and is evaporated by the process of transpiration. The xylem is also composed of elongated cells like the phloem.

Detailed explanation-4: -The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant.
