Final answer:
Major plant groups are characterized by the presence or absence of vascular tissue, seeds, and reproductive structures like flowers or cones. Nonvascular plants lack these features, while vascular plants are categorized into seedless varieties like ferns and seed-producing varieties, which include gymnosperms with cones and angiosperms with flowers.
Therefore , option 2) is correct.
Step-by-step explanation:
Characteristics of Major Plant Groups
The characteristics of major plant groups involve differences in vascular tissue, seed production, and reproductive structures. Nonvascular plants, such as mosses, liverworts, and hornworts, lack specialized tissues for nutrient and water transport and do not produce seeds or flowers. These are typically found in moist environments due to their direct absorption of water.
Vascular plants developed specialized systems, including xylem and phloem, which allow for more efficient transport of water and nutrients. This group can be sub-divided into the seedless vascular plants, like ferns and horsetails, which reproduce via spores, often produced in cones or cone-like structures called strobili. Finally, seed plants are split into gymnosperms, which produce seeds in cones, and angiosperms, which produce seeds within flowers that later develop into fruits.
Thus, the correct characteristic combination for the major plant groups that include vascular tissue, seeds, and flowers is unique to angiosperms. Seedless vascular plants have vascular tissue and spores but not seeds or flowers. And non-vascular plants do not have vascular tissue, seeds, or flowers, and are often found in damp environments due to their reliance on passive water absorption.
