What type of cell membrane model is shown? Who were the proponents of this model?

Fluid Mosaic Model of Singer and Nicholson

What type of cell membrane model is shown? Who were the proponents of this model?

Glycocalyx and it gives the cell structural integrity and chemical protection

What part of the cell is this? What is its function?

Rough Endoplasmic Reticulum and it synthesizes and stores secretory proteins

What part of the cell is this? What is its function?

Smooth Endoplasmic Reticulum and it has different function depending on where it is located:

* Detoxification in the Liver
* Calcium release and recapture in striated muscles
* Biosynthesis of steroids in endocrine cells
* Synthesis of neutral fats in intestinal villi
* Formation of HCl in parietal cells of the stomach

What part of the cell is this? What is its function?

Golgi Complex and it packages secretory Products within vesicles that fuse with the plasma membrane during exocytosis
