Detailed explanation-1: -The two forms of vascular tissue-xylem and phloem, transport water, minerals, and photosynthetic products throughout the plant. An vascular plant, as opposed to a nonvascular plant, may grow significantly larger.
Detailed explanation-2: -Nonvascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. Another characteristic of nonvascular plants that sets them apart from vascular plants is that they lack roots.
Detailed explanation-3: -The combination of one xylem and one phloem strand adjacent to each other is known as a vascular bundle. The evolution of vascular tissue in plants allowed them to evolve to larger sizes than non-vascular plants, which lack these specialized conducting tissues and are thereby restricted to relatively small sizes.
Detailed explanation-4: -Nonvascular plants were the first plants to evolve. Compared to other plants, their small size and lack of specialized structures, such as vascular tissue, stems, leaves, or flowers, explains why these plants evolved first.
