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: -An estimated 70–80 species of vascular plants grow along the shallow shores of the Baltic Sea. 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.
