* Vascular plants: These plants possess specialized tissues called xylem and phloem, which transport water and nutrients throughout the plant. Examples include trees, ferns, and flowering plants.
* Nonvascular plants: These plants lack vascular tissue and rely on diffusion to transport water and nutrients. They are typically small and live in moist environments. Examples include mosses, liverworts, and hornworts.
So, the presence or absence of vascular tissue is a defining characteristic used to categorize plants, not other types of organisms.
