Study Notes
Levels of Biological Organization
- The hierarchy of life starts from atoms, the smallest unit of matter, to molecules, leading to cells, tissues, organs, organ systems, and organisms.
- Cells are the basic structural and functional units of life, which can be unicellular or multicellular.
- Organelles within cells support their structure and function; cells can be either prokaryotic (no membrane-bound nuclei) or eukaryotic (membrane-bound organelles).
Characteristics of Living Organisms
- Eight key characteristics distinguish living organisms from nonliving entities: cellular makeup, reproduction, growth and development, metabolism, irritability, adaptation and evolution, movement, and homeostasis.
- The complexity and organization of living organisms arise from their cellular structure and the interactions between different levels of biological organization.
Tissues and Organs
- Similar cells combine to form tissues, which perform specific functions; common examples include smooth muscle, cardiac muscle, and vascular tissue in plants.
- Tissues group together to form organs (e.g., heart, liver, plant roots, leaves) that fulfill broader physiological roles.
Organ Systems and Organisms
- Organs that work together form organ systems, such as the circulatory system, which includes the heart and blood vessels to transport blood.
- An individual entity, such as a plant or animal, is referred to as an organism, with bacteria classified as microorganisms.
Emerging Properties
- At each level of biological organization, emergent properties arise that are unique to that level— characteristics that cannot be predicted merely from the lower levels.
- Structure-function correlation is evident as the design of each level is critical to its function, emphasizing the importance of organization in biological systems.
