Study Notes
Levels of Organization in Living Things
- Living organisms are characterized by a highly organized structure and are arranged in a hierarchical pattern.
Atomic Level
- Atoms are the smallest scale and the fundamental unit of matter.
Molecular Level
- Molecules are chemical structures consisting of at least two atoms held together by one or more chemical bonds.
- DNA is a molecule that contains the instructions for the structure and functioning of an organism's body.
Organelle Level
- Organelles are subunits of a cell and consist of functioning biomolecules.
- Organelles take part in the chemical reactions and interactions of cellular processes in an organism.
- Examples of organelles: Mitochondria, Chloroplast.
Cellular Level
- Cells are the building blocks of life.
- Cells are classified as prokaryotic (single cell) and eukaryotic (multicellular).
- Robert Hooke discovered the cell in 1665, and Anton Van Leeuwenhoek was the first to witness a live cell under a microscope in 1674.
Tissue Level
- Tissues are groups of similar cells performing specific functions within an organism.
- Examples of animal tissues: Epithelial, Muscle, and Nervous Tissues.
- Examples of plant tissues: Vascular, Dermal, and Ground Tissues.
Organ Level
- Organs are collections of tissues grouped together to perform a common function.
- Examples of vital organs in animals: heart, brain, lungs, etc.
- Examples of vital organs in plants: roots, stems, leaves, etc.
Organ System Level
- Organ systems are higher levels of organization that consist of functionally related organs.
Organism Level
- Organisms are living individual entities composed of various organ systems that function together.
Population Level
- Populations are groups of organisms of the same species living together within a specific area.
Community Level
- Communities are groups of organisms composed of different species that interact with each other in a certain area.
Ecosystem Level
- Ecosystems are groups of organisms that interact with their non-living environment (air, nitrogen, soil, rainwater, etc.).
Biosphere Level
- The biosphere is the global sum of all ecosystems and represents the zone of life on earth.
