Question

Почему лишайники выделяют в самостоятельную группу комплексных организмов

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. Растениями являются одноклеточные зеленые водоросли, которые в процессе фотосинтеза образуют органические вещества и обеспечивают ими грибы, а грибница снабжает водоросли водой и защищает. Эти особенности позволяют лишайникам первыми заселять самые бесплодные места.

Why Lichens are Classified as a Distinct Group of Organisms

Lichens are classified as a distinct group of organisms due to their unique symbiotic relationship between fungi and algae or cyanobacteria. This symbiosis sets them apart from other organisms and justifies their separate classification.

Symbiotic Relationship: Lichens are a composite organism consisting of a fungus and a photosynthetic partner (either algae or cyanobacteria). This mutualistic relationship is essential for the survival of lichens and distinguishes them from other organisms.

Distinctive Characteristics: Lichens possess distinctive characteristics that differentiate them from other organisms. These include their unique growth form, ability to colonize harsh environments, and their role as bioindicators of environmental health.

Environmental Adaptations: Lichens have the ability to colonize a wide range of substrates, including rocks, tree bark, and soil, and can survive in extreme environments such as deserts, Arctic tundra, and polluted urban areas. This adaptability is a defining feature that justifies their classification as a distinct group of organisms.

Ecological Significance: Lichens play a crucial role in ecological processes such as nitrogen fixation, soil formation, and providing food and habitat for various organisms. Their ecological significance further supports their classification as a distinct group of organisms.

In summary, lichens are classified as a distinct group of organisms due to their unique symbiotic relationship, distinctive characteristics, environmental adaptability, and ecological significance. These factors collectively set lichens apart from other organisms and justify their separate classification.
