Term | Definition |
---|---|
Organism | An organism is a living entity that can carry out essential life processes such as growth, reproduction, and response to stimuli. |
Cell | Cells are the basic building blocks of all living organisms. |
Unicellular | Unicellular organisms are living organisms that consist of a single cell |
Multicellular | Multicellularity refers to the state of an organism being composed of multiple cells that work together to form a cohesive structure. |
Metabolism | Metabolism refers to the series of chemical reactions that occur within cells to sustain life. |
Stimulus | a stimulus is something that prompts a reaction or change in an organism. |
Response | the reaction or behavior that occurs as a result of receiving a specific stimulus |
Development | Development refers to the process of growth and change that occurs in living organisms over time. |
Asexual reproduction | Asexual reproduction is a type of reproduction that does not involve the fusion of gametes (sex cells) from two parents. |
Sexual reproduction | Sexual Reproduction involves the fusion of specialized reproductive cells called gametes, which come from two parent organisms. |
Spontaneous generation | Spontaneous generation, also known as abiogenesis, is the idea that living organisms can arise from non-living matter. |
Autotroph | Autotrophs are organisms that can produce their own food using energy from sunlight (photosynthesis) or inorganic compounds (chemosynthesis). |
Heterotroph | Heterotrophs are organisms that cannot produce their own food and rely on consuming organic matter for energy and nutrients. |
Classification | Classification is the process of categorizing or grouping things based on their shared characteristics or properties. |
Taxonomy | Taxonomy is the scientific discipline of classifying and categorizing organisms based on their characteristics and evolutionary relationships. |
Binomial nomenclature | Binomial nomenclature is a system of naming species in biology. Ex. Gallus domesticus |
Genus | The term 'genus' refers to a taxonomic rank below family and above species. A genus is a group of closely related species that share common characteristics and are believed to have a common ancestor. Ex. Gallus |
Species | Species are groups of organisms that share common characteristics and can interbreed to produce fertile offspring. Ex. domesticus |
Prokaryote | Prokaryotes are a group of organisms that lack a nucleus and other membrane-bound organelles. They include bacteria and archaea. |
Eukaryote | Eukaryotes are a type of organism that have cells with a distinct nucleus enclosed by a membrane. They include plants, animals, fungi, and protists. |
Nucleus | The nucleus is a vital component of cells, found in both plant and animal cells. It is often described as the control center of the cell because it contains the cell's genetic material, DNA. |
Evolution | Evolution is the process by which species change over time through the accumulation of genetic variations. |
Branching tree diagram | A branching tree diagram is a visual representation that depicts the hierarchical relationships and evolutionary history of different entities, such as species, organisms, or concepts. |
Shared derived characteristics | Shared derived characteristics, also known as synapomorphies, are traits or features that are shared by a group of organisms and are derived from a common ancestor. |
Convergent evolution | Convergent evolution refers to the phenomenon where different species independently evolve similar traits or characteristics in response to similar environmental pressures. |
