Detailed explanation-1: -Vascular plants are efficient in growth and development due to the presence of vascular tissues: xylem and phloem. Xylem is responsible for the transport of water and nutrients from the roots to the rest of the plant. Phloem carries the sugars made in the leaves to the parts of the plant where they are needed.

Detailed explanation-2: -They do not have a phloem or xylem. 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: -Vascular systems are able to allow plants to grow bigger due to the ability to transport nutrients and sugar over why distances. This also allows plants to live further away from water sources, and dominate early terrestrial environments. The vascular system of plants includes the xylem and the phloem.

Detailed explanation-5: -The two types of vascular tissue, xylem and phloem, are responsible for moving water, minerals, and the products of photosynthesis throughout the plant. As opposed to a non-vascular plant, a vascular plant can grow much larger.
