NOTE
CLASSIFICATION OF LIVING THINGS 1
Classification
Classification refers to the systematic arrangement of organisms into hierarchical groups based on shared characteristics and evolutionary relationships. This process is known as taxonomy, involves categorizing living organisms into increasingly inclusive groups, from broad categories like domains and kingdoms to more specific ones like phyla, classes, orders, families, genera, and species. The goal of classification is to organize the immense diversity of life, making it easier to study, understand, and communicate about different species and their relationships.
Binomial system of nomenclature
The binomial system of nomenclature is a standardized naming convention for biological species, introduced by Carl Linnaeus. It involves assigning each species a two-part name, consisting of the genus name followed by the species identifier. This system is based on Latin and is designed to provide a universally recognized and consistent way of naming organisms.
For example, in the binomial name "Homo sapiens," "Homo" is the genus, and "sapiens" is the species. The first part (genus) is always capitalized, and the second part (species) is in lowercase. The entire binomial name is italicized when printed or underlined when handwritten.
This system helps in accurately identifying and communicating about different species, regardless of language differences, and reflects the evolutionary relationships among organisms.
Kingdom
A kingdom is a high-level taxonomic rank that groups together organisms based on certain fundamental characteristics. Traditionally, five major kingdoms are recognized:
2. Protista: Comprises mostly unicellular eukaryotic organisms. This kingdom is diverse and includes protozoans, algae, and other simple eukaryotes.
3. Fungi: Includes organisms like mushrooms, molds, and yeasts. Fungi are eukaryotic and often absorb nutrients from their surroundings.
4. Plantae: Composed of multicellular, eukaryotic organisms capable of photosynthesis. This kingdom encompasses a wide range of plants, from mosses to flowering plants.
5. Animalia: Consists of multicellular, eukaryotic organisms with specialized tissues. This kingdom includes a vast array of animals, from sponges to mammals.
