Give at least 3 defining features of mosses

Question

Identify at least 1 species of moss. Give both the scientific and the common name.
Where is this moss commonly found?

Answer 1

Defining Features of Mosses:

1. Non-Vascular Plants: Mosses are non-vascular plants, meaning they do not have specialized tissues (xylem and phloem) for transporting water and nutrients. Instead, they rely on diffusion and osmosis.

2. Gametophyte Dominance: The life cycle of mosses is dominated by the gametophyte stage, which is the green, leafy part that we typically recognize as moss. The sporophyte, which produces spores, is dependent on the gametophyte for nutrition.

3. Moisture Requirement: Mosses thrive in moist environments, as they need water for reproduction (sperm must swim to the egg for fertilization) and to maintain their physiological processes. They often grow in shaded, humid areas, such as forest floors, rocks, or tree trunks.

Species of Moss:

• Scientific Name: Sphagnum palustre
• Common Name: Peat Moss

Common Habitat:

Peat moss (Sphagnum palustre) is commonly found in wetlands, marshes, and bogs, where it plays a significant role in the formation of peat soil and in maintaining the acidity and water retention of the habitat.
