Detailed explanation-1: –Tracheophytes have leaf, root and stem. They reproduce either through spores or through seeds. They have developed vascular systems and have xylem and phloem present. They are covered with a thick layer of wax to help them in protection.

Detailed explanation-2: -The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.

Detailed explanation-3: -Taproot is an example of true root. It is the main root descending downward from the radicle and giving off small lateral roots.

Detailed explanation-4: -Pteridophytes has proper vasculature, which means xylem and phloem is present. Plants do not have roots, instead, rhizoids are present and help in anchoring. Roots are present in these plants. It does not have any true stems or leaves.

Detailed explanation-5: -A true root system consists of a primary root and secondary roots (or lateral roots). the diffuse root system: the primary root is not dominant; the whole root system is fibrous and branches in all directions. Most common in monocots. The main function of the fibrous root is to anchor the plant.
