Study Notes
Meaning and Concept of Classification
- Classification involves grouping organisms based on shared features, simplifying the study of vast biodiversity.
- Establishes relationships between organisms by organizing them into categories like kingdom, phylum, class, order, family, genus, and species.
Hierarchies in Classification
- Kingdom is the highest classification category, while species is the lowest.
- The five kingdoms identified in current classification are: Monera, Protista, Fungi, Plantae, and Animalia.
Binomial System of Naming Organisms
- The binomial nomenclature gives each organism a scientific name consisting of two parts: the generic name and the specific name.
- Names are usually derived from Latin or Greek, ensuring universal understanding among scientists.
- Example scientific names include Homo sapiens for humans and Panthera tigris for tigers.
Two-Kingdom Classification
- An outdated system proposed by Carolus Linnaeus that divided living organisms into two kingdoms: Plant Kingdom and Animal Kingdom.
- Plant Kingdom: Autotrophic, fixed organisms with cell walls, capable of photosynthesis.
- Animal Kingdom: Heterotrophic, motile organisms without fixed cell walls.
Advantages and Disadvantages of Two-Kingdom Classification
- Advantages include simplicity and clear categorization of organisms.
- Disadvantages include the inaccurate grouping of certain organisms like bacteria and fungi and many organisms not fitting into either kingdom.
Contributions to Classification
- Ernst Haeckel added the Protista kingdom.
- Herbert Copeland introduced Kingdom Monera and Kingdom Fungi.
- Robert Whittaker proposed the five-kingdom classification in 1969, refining previous systems.
Five-Kingdom Classification
- Kingdom Monera: Unicellular prokaryotes.
- Kingdom Protista: Unicellular eukaryotes.
- Kingdom Fungi: Unicellular or multicellular eukaryotes, heterotrophic.
- Kingdom Plantae: Multicellular eukaryotes with chlorophyll, autotrophic.
- Kingdom Animalia: Multicellular eukaryotes, heterotrophic, lacking chlorophyll.
Kingdom Monera
- Comprises unicellular, microscopic prokaryotes; possess rigid cell walls.
- Can be autotrophic or heterotrophic; examples include E. coli and Cyanobacteria.
- Bacteria play a crucial role as decomposers and in nutrient recycling.
Useful Bacteria
- Bacteria are essential for processes like making curd, nitrogen fixation, and antibiotic production.
- Facilitate soil fertility through nitrogen-fixing species like Rhizobium.
Harmful Bacteria
- Cause food spoilage and various diseases in humans (e.g., cholera, tuberculosis), animals, and plants.
Kingdom Protista
- Consists of unicellular, eukaryotic microorganisms with well-defined nuclei and membrane-bound organelles.
- Exhibit diverse modes of nutrition; examples include Amoeba, Paramecium, and Euglena.
Structure and Nutrition in Amoeba
- Amoeba has a flexible shape and moves using pseudopodia, engulfing food through these extensions.
- Food digestion occurs in food vacuoles, with waste expelled afterward.
Cell Division in Amoeba
- Mitosis results in the creation of identical daughter cells, essential for growth and repair.
- Cell cycle phases include interphase, mitosis, and cytokinesis.
Multiple Fission in Amoeba
- Occurs in unfavorable conditions, resulting in the formation of cysts to survive harsh environments.
- Under favorable conditions, cysts release new Amoeba (pseudopodiospores).
Kingdom Fungi
- Eukaryotic organisms lacking chlorophyll, cannot photosynthesize.
- Thrive on decaying organic matter, functioning as saprophytes or parasites.
