Question

Почему даже самые крупные мхи не достигают размеров более 80 сантиметров

Answer 1

Потому что для роста мхов не очень неблагоприятные условия.

Answer 2

Why don't even the largest mosses reach sizes of more than 80 centimeters?

Mosses are a type of small, non-vascular plants that belong to the division Bryophyta. They are characterized by their small size and lack of true roots, stems, and leaves. While there are some moss species that can grow quite large, it is true that even the largest mosses do not typically exceed sizes of more than 80 centimeters.

There are several reasons why mosses do not grow larger:

1. Lack of vascular tissue: Mosses lack vascular tissue, which is responsible for transporting water and nutrients throughout the plant. Without this specialized tissue, mosses rely on osmosis and diffusion to absorb water and nutrients from their surroundings. This limits their ability to grow larger because they cannot efficiently transport resources to all parts of the plant.

2. Limited structural support: Mosses have simple structures and lack the complex tissues that provide structural support in larger plants. This makes it difficult for them to grow taller without collapsing under their own weight. The lack of lignin, a substance that provides rigidity to plant cell walls, also contributes to their limited structural support.

3. Environmental factors: Mosses are adapted to grow in moist and shaded environments, such as forests, where they can thrive in competition with other plants. In such environments, there is limited space and resources available for plant growth. This competition for resources can restrict the size that mosses can attain.

It is important to note that while most mosses do not grow larger than 80 centimeters, there are exceptions. Some species of moss, such as Dawsonia superba, can reach heights of up to 50 centimeters or more. However, these larger mosses are still relatively small compared to other types of plants.

Overall, the size limitation of mosses is primarily due to their lack of vascular tissue, limited structural support, and the environmental conditions in which they typically grow.
