10 Questions
What is cell biology?
Branch of biology studying the structure and function of the cell, the basic unit of life.
Define a cell.
The basic structural, functional, and biological unit of all known organisms.
How has modern-day cell biology research impacted the study of human anatomy and physiology?
It looks at ways to culture and manipulate cells outside of a living body for further research.
What are some techniques commonly used in studying cell biology?
Cell culture and fluorescence microscopy.
What does fluorescence microscopy use to label specific components of a cell?
Fluorescent markers such as GFP.
What is the main principle behind phase-contrast microscopy?
Uses the optical aspect of light to represent the solid, liquid, and gas phase changes as brightness differences.
How does confocal microscopy differ from traditional fluorescence microscopy?
Combines fluorescence microscopy with imaging by focusing light and snap shooting instances to form a 3-D image.
What is the main technique used in transmission electron microscopy to visualize cellular components?
Involves metal staining and the passing of electrons through the cells.
How does cell fractionation help in studying cells?
Breaking up the cell using high temperature or sonification followed by centrifugation to separate the parts of the cell.
What is the key difference between finite cell lines and continuous cell lines?
Finite cell lines have a limited number of divisions before senescence, while continuous cell lines can divide indefinitely.
Explore the fundamental concepts of cell biology, studying the structure and function of cells, including prokaryotic and eukaryotic cells. Topics may include cell metabolism, communication, cycle, biochemistry, and composition.
