Study Notes
Introduction to Fungi
- Mycology is the study of fungi.
- Fungi are characterized by their thallus structure, lacking chlorophyll for photosynthesis.
- They are distinguished from other organisms by their lack of chlorophyll and differentiation into true roots, stems, and leaves.
- Fungi have a cell wall and nucleus but lack chlorophyll and vascular tissues.
- Slime moulds are sometimes included in the Myxomycetes group alongside fungi, although some mycologists consider them separate.
- Bacteria are excluded due to their lack of a nucleus.
Habitat and Occurrence
- Fungi are ubiquitous with over 100,000 species distributed worldwide.
- They thrive in various habitats where organic material is available.
- Their lack of chlorophyll means they do not require light for growth.
- Fungi flourish in moist, dark, and warm conditions.
- Can be found in extremely cold temperatures and hot deserts.
- Some spores and conidia can survive in completely dehydrated conditions.
- The most usual habitat is wet soil rich in humus.
- Fungi found in these habitats are considered advanced, such as Agaricus, Morchella, and Peziza.
- Some are aquatic, like Saprolegnia, considered primitive.
- Some are subterranean (growing underground).
- They can contaminate foodstuffs like bread, jams, pickles, fruits, and vegetables.
- Some can contaminate drinking water.
- Can be parasitic to plants and animals, causing diseases like candidosis (caused by Candida albicans) and aspergillosis (caused by Aspergillus sp.).
Nutrition and Relationships
- Fungi are heterotrophic, meaning they obtain food from other organisms.
- They are either saprophytes, which feed on dead organic matter, or parasites, which live on living organisms.
- Saprophytes play an important role in breaking down dead organic matter and recycling nutrients.
- Parasites can cause disease in their hosts, such as the potato blight caused by Phytophthora infestans.
- Some fungi have symbiotic relationships, such as mycorrhizae, where they live in close association with plant roots, exchanging nutrients and water.
