Phycomycetes
Phycomycetes are known as the lowest class of true fungi. Phycomycetes organisms are located all over the world in soil, animal manure, and on fruits. Frequently, the fungi of this class are found in refrigerators and are commonly called bread molds.
Characteristics
- They are called algal fungi, and they are found in aquatic habitats, damp places, and on decaying wood in moist or as an obligate parasites on plants.
- They can be parasites or saprophytes.
- Mycelium is coenocytic and aseptate
- The wall of the hyphae is made up of cellulose.
- Asexual reproduction takes place by zoospores (motile) or aplanospores(non-motile).
- Sexual reproduction takes place by gametangial contact, in which male gamete is transferred from the antheridium to the oogonium.
- At the end of sexual reproduction, oospores will be produced.
- Common examples are- Rhizopus, Mucor, and Albugo.
Phycomycetes
Biological classification can be defined as the method used to categorize and group living organisms based on their features and functions, also known as taxonomy. The first biological classification is done by Aristotle, who classified living organisms based on morphological characteristics. According to the classification of Aristotle, organisms can be classified as Organisms that have red blood cells and Organisms that don’t have red blood cells. After that, Carolus introduced the system of kingdoms. According to him, there are two kingdoms, Animalia and Plantae. But still, there are some organisms that didn’t get any categorization from this classification. Then R.H. Whittaker classified organisms. R.H. Whittaker classified living organisms into 5 kingdoms based on their cell structure, complexity, reproduction, mode of nutrition, and phylogenetic relationships. The five kingdoms are Monera, Protista, Fungi, Animalia, and Plantae.
