Study Notes
Characteristics of Life
- Organization: Life exhibits a hierarchy where cells form tissues, tissues create organs, and organs are organized into organ systems.
- Metabolism: Autotrophs harness energy from sunlight to sustain life processes.
- Homeostasis: Organisms maintain a stable internal environment; human body temperature is an example, typically around 37 degrees Celsius.
- Reproduction and Development: Growth phases such as puberty represent developmental milestones in many living organisms.
- Evolution: Bacterial populations can develop antibiotic resistance, leading to increased prevalence of resistant genes over time.
Key Characteristics of Living Things
- Composed of cells: All living organisms are made up of one or more cells.
- Internal regulation: Living beings regulate their internal environments to adapt and survive.
- Reproductive capability: Living organisms have the ability to reproduce and grow.
Levels of Biological Organization
- Atom: Basic units of matter.
- Molecule: Groups of atoms bonded together.
- Organelle: Specialized structures within a cell.
- Cell: The smallest unit of life.
- Tissue: Groups of similar cells performing a specific function.
- Organ: Composed of different tissues working together.
- Organ System: A group of organs that work collectively for a common purpose.
- Organism: An individual living entity.
- Population: A group of organisms of the same species in a specific area.
- Community: Different populations interacting in a shared environment.
- Ecosystem: A community along with its physical environment.
- Biosphere: The global sum of all ecosystems; the zone of life on Earth.
Domains of Life
- Archaea: Unicellular prokaryotic organisms found in extreme environments.
- Bacteria: Single-celled organisms without a nucleus; examples include streptococcus bacteria.
- Eukarya: Includes complex multicellular organisms such as fungi, plants, and animals.
Taxonomic Classification
- Kingdom: Examples include Fungi and Animalia.
- Domain: Eukarya represents the most general and least specific taxonomic category.
- Prokaryotes: Not a kingdom or domain; refers to a group of organisms lacking a nucleus.
Questions in Biology
- Relevant biological questions may include the impact of water pollution on fishing, or the evolutionary effects of antibiotic prescriptions on bacterial species.
Classification of Species
- Species classification into domains is not determined solely by the five qualities of life; this statement is false.
