NEET BIOLOGY

Detailed explanation-1: -Vascular plants are also known as tube plants (tracheophytes). The presence of vascular tissues such as xylem (tube-like) and phloem ( tubular cells) plays a role in distributing food and water to the plant cells. Other ordinary characteristics include stems, leaves, and roots that hold the plant and provide support.

Detailed explanation-2: -Both bryophtes (the mosses) and seedless vascular plants (mostly ferns) rely on water fertilization, do not have complex xylem and phloem, do not have complex gametophytes, and simple root like systems instead of the roots you see in other vascular groups.

Detailed explanation-3: -Hence, the correct answer is option B, protonema of moss and prothallus of Dryopteris are gametophytic.

Detailed explanation-4: -The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.
