The root cap is a thimble-like structure that covers the root at the apex. Which option best describes it?

Explanation:
The key idea is that the root cap is a protective, thimble‑like cover at the tip of the root. It shields the growing apical meristem as the root pushes through soil and also secretes mucilage to ease movement; it even helps gravity perception to orient the growth downward. The description that best fits is a thimble-like structure that covers the root at the apex. The other ideas describe parts of leaves, stem protection, or storage tissues, which aren’t what the root cap is.
