What type of plant is characterized by having simple parts and lacking vascular tissue?

Moss represents a type of plant known as a bryophyte, which is characterized by its simple structure and absence of vascular tissue. Vascular tissues, such as xylem and phloem, are specialized for transporting water and nutrients throughout more complex plants. Because mosses lack these tissues, they are typically small and found in moist environments where they can absorb water directly through their leaves. This lack of vascular structure also limits their height and size compared to vascular plants.

Mosses reproduce via spores rather than seeds, which is another characteristic feature of this group. Their simple parts, such as the leaf-like structures and stems, contribute to their designation as non-vascular plants, setting them apart from more complex plant types like ferns, bamboo, and cacti that do possess vascular tissue facilitating greater size and structural complexity.
