Levels of Organization
This level is defined as groups of similar cells performing a common function.
What is a tissue?
This tissue type is responsible for contraction and movement.
What is muscle tissue?
This type of epithelial tissue has one layer.
What is simple epithelium?
This organelle produces ATP (energy).
What is the mitochondria?
This is the state of relative consistency of the internal environment.
What is homeostasis?
This level is composed of 2 or more tissues.
What is an organ?
This tissue type is most diverse in structure.
What is connective tissue?
This type of epithelial tissue has several layers.
What is stratified epithelium?
This structure stores genetic material.
What is the nucleus?
This type of feedback loop maintains a set point.
What is negative feedback?
This is the correct order from smallest → largest.
What is cells → tissues → organs → organ systems?
This tissue type is responsible for signaling between cells.
What is nervous tissue?
This epithelial type is thin and allows for gas exchange (lungs).
What is simple squamous?
This organelle modifies and processes proteins.
What is the Golgi apparatus?
This type of feedback loop amplifies a response.
What is positive feedback?
This level regulates the overall organism and includes multiple organs working together.
What is an organ system?
This tissue type forms membranes, protects surfaces, and forms glands.
What is epithelial tissue?
This epithelial type is cube-shaped and found in kidneys.
What is simple cuboidal?
This structure acts as the outer boundary of the cell.
What is the plasma membrane?
In a feedback loop, this component gathers information from the environment.
What is a receptor (sensor)?
This is the lowest level mentioned in organization that contains organelles like mitochondria and nucleus.
What is a cell?
These are the primary cell types in nervous tissue that send signals.
What are neurons?
This epithelial type is rectangular and allows different functions at different ends of the cell.
What is simple columnar?
This process follows DNA → RNA → protein.
What is the central dogma?
This is the ideal body temperature example used as a set point.
What is 98.6°F?
