C - They have rhizoids instead of roots to help support the structure of the plant

Answer: D - They lack vascular tissue to move food and water throughout the plant.
NON-VASCULAR plants are small, simple, and less advanced than most plants. Mosses, liverworts, and hornworts are the three main groups. They have no transport system for food or nutrients due to their small size. They have rhizoids instead of roots, which help anchor the plant.
