REINO FUNGI 🍄 (Definición, Características y Clasificación)
What is the Fungi Kingdom?
Overview of the Fungi Kingdom
- The fungi kingdom, also known as Mikota, is one of the five taxonomic kingdoms of biological evolution alongside Animalia, Plantae, Protista, and Monera.
- It includes all eukaryotic organisms classified as fungi, with approximately 144,000 known species and an estimated 1.5 million yet to be discovered.
Characteristics of Fungi
- Fungi are heterotrophic organisms that acquire nutrients from external sources. They have a resistant chitin cell wall that helps prevent dehydration and other environmental challenges.
- Reproduction occurs via spores; both asexual (without fruiting bodies) and sexual reproduction methods exist among different fungi species.
- The mycelium, composed of long filaments called hyphae, constitutes the true body of the fungus while visible fruiting bodies produce spores for reproduction.
Diversity in Form and Function
- Fungi exhibit a wide variety of colors and sizes; they can grow in various forms such as shelves on trees or star shapes. This diversity contributes to their ecological roles in different environments.
Classification of Fungi
Major Groups within the Fungi Kingdom
- Basidiomycetes: Characterized by basidiospores and mushroom-shaped fruiting bodies.
- Ascomycetes: Contain ascospores within reproductive structures called asci; notable for molds used in food production like blue cheese.
- Glomeromycetes: Known for forming mycorrhizal structures that create symbiotic relationships with plants through glomerules pores.
- Zygomycetes: Commonly referred to as "Moss," this group includes around 1000 species with zygospores for reproduction.
- Chytridiomycetes: Includes microscopic fungi with flagellated gametes; significant for their role in aquatic ecosystems and soil health.
Examples of Notable Species
- Ascomycetes examples include Penicillium molds used for making blue cheese or wines.
- Basidiomycetes include edible varieties like cow's tongue mushrooms but also poisonous types such as panther's hand mushrooms.
