Study Notes
Cell Biology Terms
- Tissue culture is a technique used to keep cells alive and grow in an in vitro environment.
- Anisocytosis is a term used in histology and cytopathology to describe variability in the size, shape, and staining of cells.
Prokaryotic Cell Regions
- A prokaryotic cell has three regions: cytoplasm, cell membrane, and nucleoid.
Membrane Proteins
- Membrane proteins have two types: peripheral proteins and integral proteins.
Transmission Electron Microscopy (TEM)
- When preparing samples for TEM, the tissue is postfixed in osmium tetroxide for 1-2 hours.
Plasma Membrane Model
- The most acceptable model of the plasma membrane is the fluid mosaic model.
Nucleolus Function
- The nucleolus is the site for synthesis of ribosomal RNA.
Facilitated Diffusion
- Facilitated diffusion does not require energy.
Co-transported Ions
- In humans, sodium is a commonly co-transported ion across the plasma membrane.
Membrane Carbohydrates
- Membrane carbohydrates may be covalently bonded to lipids forming glycolipids or to proteins forming glycoproteins.
Cell Biology Definition
- Cytology is a branch of biology that studies the structure, function, and behavior of cells.
