Final answer:
The statement is true; vascular plants typically possess true roots, stems, and leaves. These structures are supported by vascular tissues which enable these plants to absorb more nutrients, anchor securely, grow larger, and optimize photosynthesis, setting them apart from nonvascular plants.
Step-by-step explanation:
The statement that vascular plants usually have true roots, stems, and leaves is true. Vascular plants, also known as tracheophytes, have evolved specific structures that allow them to thrive on land. These plants possess vascular tissues - namely, xylem and phloem - which enable efficient transport of water, minerals, and nutrients throughout the plant.
True roots in vascular plants allow for greater water and mineral absorption compared to the rhizoids found in nonvascular plants. Additionally, roots provide a strong anchor, enabling these plants to grow larger. The stems of vascular plants contain vascular tissues and lignin, giving them rigidity to reach higher for light and air while still being supplied with necessary moisture. Over time, the evolution of leaves from small needle-like structures to larger, broader ones allowed plants to increase their photosynthetic capabilities and therefore grow taller and more complex.
Contrastingly, nonvascular seedless plants lack these vascular tissues and therefore do not have true roots, stems, or leaves, which limits their size and habitat to moist environments where water and nutrient movement can occur without vascular tissues. The presence of these complex structures is a hallmark of vascular plants and a significant evolutionary advantage over nonvascular plants.
