Did you know? Why do about 90% of lichens choose green algae as their partners?
Lichens are specialized organisms that exhibit a symbiotic relationship between fungi and algae (or blue-green algae). This relationship is not only crucial to the survival of these creatures, but also plays an integral role in the ecosystem. According to research, about 90% of lichens choose green algae as their main symbiotic partner. The reasons behind this deserve further exploration.
Basic composition and ecological functions of lichens
Lichens are symbionts composed of fungi and algae or blue-green algae. This combination gives them unique morphological, physiological and biochemical properties. Organic carbon compounds produced by algae during photosynthesis play an important role in the growth of fungi. The fungus, in turn, provides a living environment, protects the algae from the outside environment, and helps it obtain water and nutrients.
"Lichens are fungi that own agriculture."
Advantages and diversity of green algae
The main photosynthetic partners in most lichens are green algae, allowing these lichens to survive in a variety of environments. Studies have shown that green algae in lichens belong to many different categories, the most common of which is Trebouxia, which belongs to the phylum Chlorophyta, and this type of algae accounts for about 20% of all lichens. These green algae usually have good photosynthetic abilities and can convert solar energy into the energy needed by lichens.
The role and process of photosynthesis
Photosynthetic partners are called photosynthetic organisms and play a crucial role in the structure of lichens. Supported by photosynthetic organisms, lichens are able to adapt to a variety of habitats and survive in conditions of scarce nutritional resources. The interaction between photosynthetic organisms and fungi is highly coordinated and affects each other's growth patterns in specific environments.
The process of lichenization
The formation process of lichens is called lichenization and involves a series of interactions and signal exchanges between fungi and photosynthetic organisms. This process includes the release of chemical signals, contact, and cell fusion. It is worth noting that this process has been successfully reproduced in the laboratory, but the timing in the natural environment is still unclear.
Interaction between lichens and ecosystems
Lichens play an important role in ecosystems, allowing them to survive in harsh environments and provide habitat for other organisms. In addition, some fungi use lichens as hosts, forming a strong interdependence.
"The way lichens survive is proof that cooperation between organisms can create extraordinary ecological results."
Conclusion
The formation and maintenance of lichens is a complex ecological process, and the main role of green algae gives it an irreplaceable position in this ecosystem. This process not only shows the collaboration and integration between living things, but also emphasizes how in nature, life depends on each other's existence and support. So, what enlightenments does such a complex symbiotic relationship bring to our ecological environment?
