Structure of Roots
Each part of a root helps the root carry out its functions. The root cap found at the far tip of the root protects the root as it continues to grow underground. Root hairs are small thread-like structures that help the root absorb water and minerals from the soil.
Once these substances enter the root hairs, there is a tissue that transports the water and minerals through the plant called xylem. Xylem is made up of connected vessels that quickly move water and dissolved minerals up the plant, almost like a straw sucking up liquid. This fast transport system can zip water from the roots to the farthest leaves in no time flat, so I like to think of it as the 'zippy xylem.' Speaking of the leaves, you might recall from a different lesson that leaves use photosynthesis to make food for the plant. That food needs to be transported to the plant cells so they can use it for energy. This is the job of phloem. Therefore, phloem is a tissue that transports food through the plant. You might want to think of the F-sound that starts the words phloem and food to help recall this term.
