真菌和地衣的区别是什么

Thekey difference在真菌和地衣之间is that fungi are simple heterotrophic organisms while lichen is a composite共生生物that forms from藻类或蓝细菌living among filaments of multiple fungi species.

The natural ecosystem is made up of countless organisms. Some of them are invisible to the naked eyes, while others are visible. Flora and fauna in an ecosystem are very complex as they contain billions of organisms. All these organisms are a part of an ecosystem and participate in it. An ecosystem comprises autotrophs that make their own food and heterotrophs that depend on others to obtain food. Sometimes, an ecosystem also has organisms that live together in a relationship with each other such as parasitic, symbiotic, or mutualistic organisms. Therefore, fungi and lichens are very important distinct organisms that are living in natural ecosystems.

What is Fungi?

真菌是简单的异养生物。异嗜性是那些无法制作食物的生物。因此，真菌依靠其他人获得食物。它们是单细胞或多细胞。真菌本质上是真核。这些真菌对于生态系统的平稳功能非常重要。真菌的研究称为真菌学。最重要的是，真菌可以在性和无性恋中繁殖。大约有144,000种属于王国真菌的生物。王国真菌包括酵母，铁锈，斑点，发霉，霉菌, and mushrooms. However, there are fungi-like organisms such as slime molds and oomycetes (water molds) that are often called fungi but do not belong to this kingdom.

真菌根据其生命周期，水果体的结构以及它们产生的孢子的类型细分为三组：多细胞丝状霉菌，宏观丝状真菌，形成大型水果体（蘑菇）和单细胞微观酵母。真菌的细胞壁由几丁质组成，这通常是昆虫外骨骼中的硬性物质。此外，真菌使用类似细丝的结构来获取食物。这些生物可以在大多数环境条件下生存。真菌甚至可以从死亡或腐烂的物质中获取食物。这就是真菌对自然生态系统至关重要的原因。

什么是地衣？

李chen is a composite symbiotic organism that forms from algae or cyanobacteria living among filaments of multiple fungi species. Lichen is, therefore, a symbiosis between fungi and algae or fungi and cyanobacteria. It is a very complex organism. Fungi are the dominant partners that give lichens most of their characteristics. In lichen, fungi provide the stable condition on which the algae or cyanobacteria can grow on land. The algae or cyanobacteria, in turn, provides the simple sugar (food) generated from photosynthesis to the fungi.

李chen can be found in a variety of habitats like on tree barks, rocks, walls, etc. Lichen is very important to the ecosystem because it can convert carbon dioxide in the atmosphere into oxygen through photosynthesis. Lichen is also very beneficial for humans as they can absorb any atmospheric pollutants such as heavy metal, carbon, or sulphur.

What are the Similarities Between Fungi and Lichen?

• Fungi and lichen are very important organisms living in natural ecosystems.
• Fungi and lichen are both helpful in reducing the environmental pollution.
• Both have heterotrophic species.
• These organisms can live on similar habitats such as trees barks, rocks, walls, etc.

真菌和地衣有什么区别？

Fungi are simple heterotrophic organisms, while lichen is a composite symbiotic organism that forms from algae or cyanobacteria living among filaments of multiple fungi species. So, this is the key difference between fungi and lichen. Furthermore, fungi usually grow in shady, dark, and moist places, while lichen usually grows freely in places that expose to air and light.

The following infographic lists the differences between fungi and lichen in tabular form for side by side comparison.

概括– Fungi vs Lichen

Fungi are heterotrophic in nature. They are eukaryotes. Fungi often can form a symbiotic relationship with green algae or cyanobacteria to produce lichen. In lichens, fungi protect algae or cyanobacteria, while algae or cyanobacteria provide food for fungi through photosynthesis. Thus, this summarizes the difference between fungi and lichen.
