Study Notes
Properties of Life
- Seven essential properties characterize all living things: Order, Regulation, Growth and Development, Energy Processing, Response to the Environment, Reproduction, and Evolution.
- Order indicates the complex, organized structures seen in living organisms, such as a pinecone's symmetry.
- Regulation allows organisms to maintain stable internal conditions despite external environmental changes, like body temperature.
- Growth and Development follow genetic instructions carried by DNA, guiding organisms throughout their life stages.
- Organisms process energy by taking in nutrients to fuel activities and releasing some as heat.
- Response to the environment involves interactions with stimuli, showcasing adaptability.
- Reproduction ensures the continuation of species, wherein individuals reproduce their own kind, emphasizing species-specific lineage.
- Evolution occurs through reproductive changes in populations over time, contributing to adaptation, as seen in certain species like the leaf insect.
Species and Taxonomy
- A species consists of organisms that coexist, interbreed naturally, and produce viable offspring.
- Taxonomy is the biological discipline focused on naming, classifying, and organizing species into broader hierarchical categories.
The Three Domains of Life
- Life is categorized into three primary domains: Bacteria, Archaea, and Eukarya.
- Prokaryotic cells, found in Bacteria and Archaea, are small, simple, and lack a nucleus or membrane-bound compartments.
- Eukaryotic cells, present in the domain Eukarya, are larger, complex and contain a nucleus and various compartments for cellular functions.
Kingdoms of Eukarya
- The domain Eukarya is divided into three kingdoms: Plantae, Fungi, and Animalia.
- Protists represent a diverse group of single-celled eukaryotes, including organisms like amoebas, that do not fit into the three main kingdoms.
Scientific Concepts
- A theory provides a broad explanation within science, capable of generating new, testable hypotheses based on existing evidence.
- Eukaryotes that do not align with established kingdoms are categorized under the group called protists.
