Cell Biology

The study of the formation, structure, components and function of cells.

Members of the American Society of Cell Biology have worked with CourseSource to create a Learning Framework for the Cell Biology Course. The table below lists the learning goals and objectives that the Society agrees any undergraduate biological sciences major should know about Cell Biology by the time they graduate. 


The following people worked to develop this society-approved Cell Biology Learning Framework:

Alison Adams (Northern Arizona University), Robert Brooker (University of Minnesota), Jennifer Carney (Finger Lakes Community College), Bradley Hyman (University of California), Michael Klymkowsky (University of Colorado), Kathryn Miller (Washington University), Susan Singer (Carleton College), Kimberly Tanner (San Francisco State University), Michael Wolyniak (Hampden-Sydney College) and Sue Wick (University of Minnesota).

The American Society of Cell Biology (ASCB), founded in 1960, is an inclusive, international community of biologists studying the cell, the fundamental unit of life. They are dedicated to advancing scientific discovery, advocating sound research policies, improving education, promoting professional development and increasing diversity in the scientific workforce.

Society Learning Goals


Membrane Structure and Function

How do varied membrane composition and the structural features of component macromolecules in different cells contribute to membrane function?

Sample Learning Objectives
  • Draw the structure of a lipid and explain how the structure allows a lipid bilayer to spontaneously assemble in an aqueous environment.
  • Explain the importance of membrane lipid and protein component structural asymmetries in membrane function.
  • Describe the process by which membranes grow, are turned over, or are absorbed.
  • Explain why different membranes have different lipid and protein constituents.

How do solutes and other materials move across membranes?

Sample Learning Objectives
  • Given a set of molecules of differing solubility in water, predict their relative rates of diffusion across a membrane bilayer.
  • Compare and contrast the properties and functions of channels and carriers.
  • Given data about the relative concentrations of solutes on both sides of a membrane, predict the direction of solute flow.
  • Design an experiment that distinguishes between different modes of crossing the membrane, such as diffusion, facilitated diffusion, active transport.
Nuclear Structure and Function

How does the structure of the nucleus affect chromosome organization and gene expression?

Sample Learning Objectives
  • Describe the arrangement of chromosomal DNA in the nucleus and how it changes during the cell cycle.
  • Compare and contrast how the presence of a nucleus in eukaryotes and its absence in prokaryotes alters the dynamics of gene expression.
  • Design an experiment to demonstrate the role of the nuclear pore complex.
  • From an evolutionary perspective, propose a mechanism that gave rise to the eukaryotic nucleus.
  • Diagram where ribosomal components are synthesized and where they are assembled.
Cytoskeleton Structure and function

How do the different components of the cytoskeleton support a variety of cell functions, such as cell shape, division, movement, sensing the environment, and cell-cell communication?

Sample Learning Objectives
  • Compare the characteristics and functions of microfilaments, microtubules, and intermediate filaments.
  • Compare the structure and dynamic properties of microtubules versus actin and how these properties contribute to the different functions of these polymers in cells.
  • Explain how motor proteins harness energy to move along cytoskeletal tracks.
Cell cycle and cell division

How do cells conduct, coordinate, and regulate nuclear and cell division?

Sample Learning Objectives
  • Predict how a mutation or other functional alteration in a cytoskeletal protein will affect the progress of nuclear and cytoplasmic division.

  • Evaluate the relative contribution of mutations in tumor suppressor genes and proto-oncogenes in the development of cancer.
  • Assess the usefulness and limitations of information obtained from several experimental techniques (i.e., TEM, atomic force microscopy, fluorescent antibody labeling, and confocal fluorescence time lapse microscopy) in dissecting cytoskeletal roles in nuclear and cell division.
  • Compare different methods used to coordinate cell division in different cell types.
  • Compare and contrast organization of the mitotic spindle in animal, fungal, and plant cells and discuss the evolutionary and functional relevance.
