What is a characteristic of nonvascular plants?

  1. They can grow very large

  2. They have vascular tissues

  3. They lack vascular tissue for transporting water

  4. They primarily reproduce by seeds

The correct answer is: They lack vascular tissue for transporting water

Nonvascular plants are defined by their lack of vascular tissues, which include xylem and phloem responsible for the transport of water, nutrients, and sugars throughout the plant. This absence means that nonvascular plants, such as mosses and liverworts, rely on diffusion and osmosis for the movement of substances, limiting their size and habitat. Because they do not have the supporting structures that vascular plants do, nonvascular plants remain small and typically grow in moist environments where water is readily available. This characteristic significantly influences their life cycle, reproduction, and ecological interactions. Therefore, recognizing that nonvascular plants lack vascular tissue is fundamental to understanding their biology.
