Study Notes
The Living World
- The living world is diverse, ranging from plants to animals, and is characterized by a wide range of habitats, including cold mountains, deciduous forests, oceans, and deserts.
- There are approximately 1.7-1.8 million known species of plants and animals.
Diversity in the Living World
- The number of species known and described ranges from 1.7-1.8 million.
- Each different kind of plant, animal, or organism represents a species.
- Biodiversity refers to the number and types of organisms present on Earth.
Nomenclature
- Nomenclature is the process of standardizing the naming of living organisms to ensure a common name worldwide.
- Scientific names are based on agreed principles and criteria, and are essential for biologists to communicate effectively.
- The International Code for Botanical Nomenclature (ICBN) provides guidelines for naming plants, while the International Code of Zoological Nomenclature (ICZN) provides guidelines for naming animals.
- Biological names are generally in Latin, written in italics, and consist of a generic name and a specific epithet (e.g., Mangifera indica).
- The first word of a biological name represents the genus, while the second word represents the specific epithet.
Classification
- Classification is the process of grouping organisms into convenient categories based on similarities.
- Taxa are categories used to study organisms, and can indicate categories at different levels (e.g., plants, animals, dogs, cats).
- Taxonomy is the branch of study that deals with the classification, identification, and naming of organisms.
- External and internal structure, development process, and ecological information of organisms are essential for modern taxonomic studies.
Taxonomic Categories
- Species: a group of individual organisms with fundamental similarities.
- Genus: a group of related species that share common characteristics.
- Family: a group of related genera that share common features.
- Order: a group of related families that exhibit a few similar characters.
- Class: a group of related orders that share common characteristics.
- Phylum or Division: a group of related classes that share common characteristics.
- Kingdom: the highest level of classification that includes all living organisms.
