What are characteristics of nonvascular plants (mosses)?

A. Presence of specialized conducting tissues
B. Lack of specialized conducting tissues
C. Production of seeds for reproduction
D. Dominance of flowers in the reproductive cycle

Answer :

Final answer:

Nonvascular plants, which include mosses, lack specialized conducting tissues, true roots, stems, and leaves, resulting in their dependence on moist environments for nutrient and water absorption. Mosses use rhizoids to anchor themselves and possess a dominant gametophyte stage in their life cycle.

Explanation:

Characteristics of Nonvascular Plants

Nonvascular plants, such as mosses, liverworts, and hornworts, are mainly characterized by the lack of specialized conducting tissues. These organisms are often small and absorb water and nutrients directly through their surfaces as they lack true roots, stems, or leaves often found in vascular plants. The communities of mosses, hornworts, and liverworts are collectively known as bryophytes and occupy moist habitats due to their reliance on the external environment to obtain water and nutrients. The life cycle of these plants is predominantly in the gametophyte stage, which is the green and photosynthetic part of the plant that we commonly observe.

Mosses may resemble leafy structures, with stem-like and root-like features known as rhizoids that help anchor them to a substrate. However, these are not considered true roots or leaves because they do not contain vascular tissue. The reproductive cycle of mosses does not include the production of seeds or the dominance of flowers, setting them apart from vascular plants with more complex life cycles.
