Which Best Describes the Structure of a Cell's Plasma Membrane
For comparison human red blood cells visible via light microscopy are approximately 8 µm wide. CAS PubMed Google Scholar.
Plasma Membrane Definition Structure Functions Biology Dictionary
The best device to do this would be a A electron microscope B light microscope C magnifying glass D dissecting microscope E unaided eye.
. 10 477486 2008. Plasma membranes range from 5 to 10 nm in thickness. Archaea ɑːr ˈ k iː ə ar-KEE-ə.
The cell from the Latin word cellula meaning small room is the basic structural and functional unit of life formsEvery cell consists of a cytoplasm enclosed within a membrane which contains many biomolecules such as proteins and nucleic acids. Robbins Basic Pathology 10th Edition. Singular archaeon ɑːr ˈ k iː ə n constitute a domain of single-celled organismsThese microorganisms lack cell nuclei and are therefore prokaryotesArchaea were initially classified as bacteria receiving the name archaebacteria in the Archaebacteria kingdom but this term has fallen out of use.
Hemidesmosomes which look like half a desmosome link. The adhesion molecule cadherin is embedded in these patches and projects through the cell membrane to link with the cadherin molecules of adjacent cells. Archaeal cells have unique properties.
The patches are structural proteins on the inner surface of the cells membrane. Resolving power is the A focusing mechanism used to bring objects clearly into view B ability to tell two points apart as separate points C ability to make an object larger D depth of the specimen clearly in focus. The pattern-recognition molecule Nod1 is localized at the plasma membrane at sites of bacterial interaction.

The fluid mosaic model describes the plasma membrane structure as a mosaic of componentsincluding phospholipids cholesterol proteins and carbohydratesthat gives the membrane a fluid character.
