NEET BIOLOGY

Detailed explanation-1: -The most basic division of living plants is between nonvascular and vascular plants. Vascular plants are further divided into seedless and seed plants. Seed plants called gymnosperms produce seeds in cones.

Detailed explanation-2: -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. The first nonvascular plants to evolve were the liverworts.

Detailed explanation-3: -Vascular plants are subdivided into two classes: seedless plants, which probably evolved first (including lycophytes and pterophytes), and seed plants. Seed-producing plants include gymnosperms, which produce “naked” seeds, and angiosperms, which reproduce by flowering.

Detailed explanation-4: -The vascular plants have two types of seed plants, including gymnosperms and angiosperms.

Detailed explanation-5: -The plants that are called “First vascular land plants” are Pteridophytes.
