We were discovered by Robert Hooke, in which he examined a piece of fungus under a light microscope and he called each space as “cellula”. It was not already possible for him to see cell membranes with the primitive light microscope he used in this study.
Fun fact… The term plasma membrane derives from the German Plasmamembran, a word coined by Karl Wilhelm Nägeli (1817–1891) to describe the firm film that forms when the proteinaceous sap of an injured cell comes into contact with water. #GootAPBio
We are the thin layer that separates the inside of the cell from the outside. Lots of things happen in our cells, including functions that we need to survive, so it is important that the right things are inside the cell when they need to be. You’re welcome. #GootAPBio
A cell's membrane is primarily made up of a double layer of phospholipids. The cell membrane is semipermeable, which allows selected molecules to pass into or out of the cell. #Keepourcellssafe#membeaneforpres#GootAPBio
