Which type of plant relies on moist environments to survive due to its lack of vascular tissue?

Nonvascular plants are indeed reliant on moist environments for survival primarily due to their lack of vascular tissue. Vascular tissue, which includes xylem and phloem, is essential for transporting water, nutrients, and food throughout a plant. Since nonvascular plants, such as mosses and liverworts, do not possess these structures, they must absorb water directly from their surroundings. This limitation keeps them close to water sources and prevents them from thriving in dry or arid environments.

In contrast, vascular plants have developed sophisticated systems that allow them to transport water and nutrients efficiently, enabling them to grow in a wider range of habitats, including drier areas. Monocots and dicots are both types of vascular plants, characterized primarily by their seed structures and leaf venation, which further distinguishes them from nonvascular plants.
