Nonvascular plants have a system that transports water and nutrients throughout the plant’s body
solniwko [45]

Answer:

False

Explanation:

Plants, based on whether they can conduct water and nutrients, are classified into vascular and non-vascular plants. Vascular plants also called TRACHEOPHYTES are plants that possess certain special tissues called vascular tissues used for conducting water and nutrients in a plant. These conducting tissues are xylem and phloem.

On the other hand, non-vascular plants do not possess vascular or conducting tissues, hence, they cannot transport water and nutrients throughout the plant. Hence, such plants are naturally found in moist areas e.g. mosses. Therefore, based on the question asked, the answer is FALSE.
