Yes, you are correct. Mosses are nonvascular plants.
Yes, "b" is correct. Mosses are a type of nonvascular plant. To determine if the other options are also correct, we need to understand what it means for a plant to be vascular or nonvascular.
Vascular plants have specialized tissues called xylem and phloem, which transport water, minerals, and nutrients throughout the plant. They have true roots, stems, and leaves. Examples of vascular plants include ferns, gymnosperms, and angiosperms.
On the other hand, nonvascular plants, like mosses, lack true roots, stems, and leaves. They do not have specialized tissues for transporting water and nutrients. Instead, they rely on direct absorption and diffusion to obtain water and nutrients. Nonvascular plants are typically small and grow in damp environments.
Therefore, among the options given, only mosses are nonvascular plants.
