Definition
They have no vascular structures.Since they lack vascular tissue, they can only absorb nutrition and water through surface tissues. Since they do not have structures to transport nutrients throughout large areas, they are limited to being short and small, like mosses and liverworts. Because they only absorb water through surface tissues, non-vascular plants can only survive underwater or in very humid environments.
