Study Notes
### Five Kingdom Classification System
- The five kingdom system is a classification system that groups living organisms into five kingdoms - Monera, Protista, Fungi, Plantae, and Animalia.
- Monera: Includes all prokaryotic organisms, which lack a defined nucleus and other membrane-bound organelles.
- Protista: Includes all single-celled eukaryotes, which have defined nuclei and other membrane-bound organelles.
- Fungi: Includes eukaryotic, heterotrophic organisms that are mostly saprophytic (decomposers) and obtain nutrients by external digestion.
- Plantae: Includes all eukaryotic, chlorophyll-containing organisms that can perform photosynthesis.
- Animalia: Includes all eukaryotic, multicellular organisms that lack cell walls and obtain nutrients by ingesting other organisms (holozoic nutrition).
Monera
- Monera includes bacteria and cyanobacteria.
- Bacteria are ubiquitous, found in various habitats like soil, water, and even extreme environments.
- Cyanobacteria are photosynthetic and are also known as blue-green algae.
- Some cyanobacteria can capture atmospheric nitrogen for their growth.
- Bacteria play significant roles in nutrient cycling and decomposition.
- Some bacteria are involved in various human activities, including food production (e.g., curd) and antibiotic production.
- Some bacteria are pathogens, causing diseases like cholera, typhoid, and tetanus.
Protista
- Protista includes a diverse group of single-celled eukaryotes, including algae, protozoa, and slime molds.
- Algae are diverse and carry out photosynthesis.
- Protozoans are heterotrophic and obtain nutrients by ingesting other organisms. Protozoans include four major groups: amoeboid protozoans, flagellated protozoans, ciliated protozoans, and sporozoans.
Fungi
- Fungi are heterotrophic, multicellular organisms, except for yeast.
- Most fungi are saprophytic and obtain nutrients by decomposing organic matter.
- Some fungi are parasitic, causing diseases in plants and animals.
- Fungi are used in various human activities, such as bread-making and beer brewing.
### Economic Importance
- Heterotrophic bacteria are involved in various processes like food production (e.g., curd), decomposition, and antibiotic production.
- Archaebacteria are extremophiles and can survive in extreme conditions, having potential applications in biotechnology.
Phycobiont and Mycobiont
- Phycobiont refers to the algal component of a lichen which provides food through photosynthesis.
- Mycobiont refers to the fungal component of a lichen, being responsible for providing shelter and absorbing water.
