Study Notes
Levels of Biological Organization
- Biological organization is a hierarchical structure that helps understand life from simple components to complex systems.
- Ranges from atoms and molecules to ecosystems, illustrating the interconnectedness of life.
Atoms and Molecules
- Atoms are the smallest units of matter and the foundational units of life.
- Molecules are formed when two or more atoms bond chemically.
- Essential molecules include water (Hâ‚‚O), carbon dioxide (COâ‚‚), proteins, and DNA.
Cells
- Cells are the smallest units capable of performing all life processes.
- Fundamental building blocks for all living organisms, including both single-celled and multicellular entities.
Organisms
- An organism is a complete living entity capable of independent survival and reproduction.
- Represents the highest tier of biological organization within an individual.
- Examples include humans, trees, dogs, and bacteria.
Populations
- A population is a group of individuals of the same species living in a specific area.
- Highlights interactions among members of the same species within ecosystems.
Organs
- Organs are structures made up of different tissues that work together for specific, complex functions.
- Examples of organs include the heart, lungs, stomach, and brain.
Organ Systems
- Organ systems consist of coordinated groups of organs collaborating to perform major bodily functions.
- Examples include the digestive system, circulatory system, nervous system, and respiratory system.
Tissues
- Tissues are organized groups of similar cells that cooperate to execute a particular function.
- Begin to show specialization and collaboration among cells.
- Examples include muscle tissue, nervous tissue, and epithelial tissue.
