Explanation

In lower plants like mosses, the structure which performs the functions of roots of higher plants is called. The question is asking us to identify the name of this structure from the options given. The options are roots hairs, rhizoids, hyphae, and roots. The correct answer is option B: rhizoids. Rhizoids are thread-like structures that anchor lower plants like mosses to the ground and absorb water and nutrients. They do not have a vascular system like true roots found in higher plants, and therefore, cannot transport water and nutrients to other parts of the plant. It is important to note that although rhizoids may perform similar functions to roots, they are not classified as roots, as they are not true roots. True roots have vascular tissues that transport water, minerals, and nutrients throughout the plant. Understanding the difference between rhizoids and true roots is essential in Biology, as it helps in the classification of plants into different groups based on their characteristics.
