Study Notes
Organization of Living Things
- All living things start with the cell, which is the basic unit of structure and function.
- Cells combine to form tissues, tissues create organs, organs establish organ systems, leading to the formation of an organism.
- Levels of organization include:
- Cell: The fundamental building block of life.
- Tissue: A group of similar cells working together to perform a specific function, with four main types: epithelial, muscular, connective, and nerve tissue.
- Organ: A structure made up of two or more types of tissues collaborating for a particular function (e.g., brain, stomach, roots, stems).
- Organ System: A collective of organs that function together (e.g., skeletal, nervous, reproductive systems).
- Organism: A single living entity that consists of one or more organ systems.
- An average human body contains approximately 38 trillion cells.
Levels Above Organisms
- Population: Organisms of the same species living in a specific area (e.g., all goldfish in one location).
- Community: All populations residing in the same area, encompassing various species (e.g., goldfish, coral, and other marine life).
- Ecosystem: The interaction of all living (biotic) and nonliving (abiotic) components in a given area, including elements like water and sunlight.
- Biome: A collection of similar ecosystems sharing comparable physical environments.
- Biosphere: The entirety of Earth that supports life, encompassing all land, water, and air, containing diverse biomes.
Diversity of Life
- Earth’s biodiversity refers to the variety of living organisms and is measured by the number of species.
- There are at least 10 million different species currently identified on Earth.
- Living organisms are classified into six main kingdoms:
- Archaea
- Bacteria
- Protista
- Fungi
- Plantae
- Animalia
