NEET BIOLOGY

Detailed explanation-1: -The xylem, vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plants. The system transports water and soluble mineral nutrients from the roots throughout the plant.

Detailed explanation-2: -Vascular plants are known as tracheophytes. Vascular tissues include xylem and phloem. They allow plants to grow tall in the air without drying out. Vascular plants also have roots, stems, and leaves.

Detailed explanation-3: -The lycophytes, which are the club mosses, were the first plant group to develop vascular tissues. Vascular plants include the club mosses, ferns, gymnosperms, and angiosperms.

Detailed explanation-4: -Pteridophytes are the first terrestrial plants to possess vascular tissues (xylem and phloem).

Detailed explanation-5: -Botanists define vascular plants by three primary characteristics: Vascular plants have vascular tissues which distribute resources through the plant. Two kinds of vascular tissue occur in plants: xylem and phloem.
