Question

Почему лишайники выделяют в самостоятельную группу опганизмов

Answer 1

Ответ:

Лишайники нельзя отнести ни к одному из царств живой природы и их выделяют в самостоятельную группу, потому что это симбиотический организм.Тело лишайника — слоевище — состоит из представителей двух разных царств: растения и грибы.

Answer 2

Потому что лишайники являются симбиотическими организмами, их тело состоит из двух разных царств: растения и грибы. Поэтому их нельзя отнести ни к одному из царств живой природы.

Answer 3

Why are lichens classified as a separate group of organisms?

Lichens are unique organisms that are classified as a separate group due to their distinct characteristics and symbiotic nature. Lichens are not a single organism but rather a composite organism consisting of a fungus and a photosynthetic partner, which is usually an alga or a cyanobacterium. This symbiotic relationship allows lichens to survive and thrive in environments where neither the fungus nor the photosynthetic partner could survive alone.

Lichens are classified as a separate group because they possess a combination of characteristics that distinguish them from other organisms. These characteristics include:

1. Symbiotic relationship: Lichens are formed through a mutualistic relationship between a fungus and a photosynthetic partner. The fungus provides a protective structure and absorbs nutrients, while the photosynthetic partner produces food through photosynthesis.

2. Unique morphology: Lichens have a unique physical appearance, often forming crust-like or leaf-like structures on rocks, trees, or soil. The morphology of lichens can vary greatly depending on the species and environmental conditions.

3. Tolerance to extreme conditions: Lichens are known for their ability to survive in harsh environments, such as deserts, arctic regions, and polluted areas. They can tolerate extreme temperatures, drought, and high levels of radiation or pollutants.

4. Environmental indicators: Lichens are sensitive to changes in environmental conditions, making them valuable indicators of air quality and ecosystem health. Certain lichen species are more sensitive to pollution and can be used to assess air pollution levels.

5. Slow growth rate: Lichens have a slow growth rate compared to other organisms. Some lichens can take several years or even decades to reach maturity.

6. Ecological role: Lichens play important ecological roles, such as providing habitat and food for various organisms, contributing to soil formation, and participating in nutrient cycling.

The classification of lichens as a separate group reflects their unique biology, ecological significance, and their ability to thrive in challenging environments.
