Economic Importance
- Phycomycetes include numerous varieties of species that attack the leaves and shoots of angiospermous plants and cause plant diseases.
- Some terrestrial species of Phycomycetes are destructive parasites of plants and certain insects.
- Other species of Phycomycetes cause food spoilage, including fruits and vegetables.
- Some species are used in industries for the fermentation purpose of various products.
- Many species of soil-inhabiting cause serious root troubles to economic plants, and others destroy the seedlings.
- Aquatic species of Phycomycetes are susceptible to Hydrogen ion concentration, which is why with the rise of temperature and falling of water level, these species decreased with the decrease in several hydrogen-ion concentrations.
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.
