Non-vascular plants grow in moist environments so they can absorb water and nutrients by osmosis and diffusion.
Non-vascular plants are plants that do not have specialized tissues (such as xylem and phloem) that conduct or circulate water throughout the plant. Due to the absence of a vascular tissue system, non-vascular plants usually grow in moist environments so they can absorb water and nutrients directly from the soil by osmosis and diffusion. Non-vascular plants do not grow very tall and they lack true leaves, stems, and roots.
