Root Hair
Root hair explained in an easy to understand way:


Imagine trying to catch rain in a small cup during a heavy downpour. Just like how using a bigger or more cups would capture more water from the rain, root hairs increase the root's surface area to absorb more water and minerals from the soil. In this analogy, the cup represents the root, the rain is the water and minerals, and the expansion into multiple cups symbolizes the root hairs, which allow the plant to effectively gather the nutrients it needs to thrive.
