A lichen thallus may be crust like crustose , scaly or leafy foliose , or shrubby fruticose , according to the species. Lichen are classified on the basis of fungal partner; most belong to the Ascomycotina. Specialised asexual reproductive structures may be produced.
Many lichens are extremely sensitive to atmospheric pollution and have been used as pollution indicators. Fungi Vs Lichen. They thrive best in the tropical and subtropical regions of the world which are warm. Require organic matter dead or living on which they feed and demand much moisture.
The thallus is generally conspicuously coloured due to the presence of various acids. The thallus is usually a filamentous mycelium, delicate in texture, immersed in substratum. In many it is slimy and gelatinous. The thallus is generally tough, leathery in texture and in many lichens it is soft as a rubber sponge. You might like Show more. Previous Post Next Post. Contact Form. 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.
Overview and Key Difference 2. What is Fungi 3. What is Lichen 4. Similarities — Fungi and Lichen 5. Fungi vs Lichen in Tabular Form 6. Fungi are simple heterotrophic organisms. Heterotrophs are those organisms that cannot make their own food. Therefore, fungi depend on others to obtain foods. They are single-celled or multicellular.
Fungi are eukaryotic in nature. These fungi are extremely important for the smooth functioning of an ecosystem. The study of fungi is termed mycology. Most importantly, fungi can reproduce both sexually and asexually. There are about , known species of organisms belonging to the kingdom fungi. Kingdom fungi include yeast, rusts, smuts, mildews, molds , 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.
Fungi are subdivided into three groups based on their life cycle, the structure of the fruiting body, and the type of spore they produce: multicellular filamentous molds, macroscopic filamentous fungi that form large fruiting bodies mushrooms , and single-celled microscopic yeasts. The cell walls of fungi are made up of chitin, which is a hard substance usually in the exoskeletons of insects.
Furthermore, fungi use filament-like structures to obtain their food. These organisms can survive in most environmental conditions.
