NEET BIOLOGY

Detailed explanation-1: -These plants lack the vascular tissue system needed for transporting water and nutrients. Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. They also lack true leaves, roots, and stems. Non-vascular plants typically appear as small, green mats of vegetation found in damp habitats.

Detailed explanation-2: -Answer and Explanation: The characteristic that is common to all vascular plants that exhibit an alternation of generations in their life cycle is b) Multicellular sporophytes.

Detailed explanation-3: -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-4: -While similar to terrestrial plants in that they also have stems, leaves, and possibly flowers, aquatic vascular plants can survive and reproduce either completely or partially underwater.
