Cell Membrane Diagram Simple. The cell membrane plays an important role in regulating the entry and exit of specific substances within the cell. It is the fluid inside the cells, which allow a number of cell organs to float inside the cell.

Using colored pencils and/or markers, sketch and color the cross section of the cell membrane onto a large piece of poster paper. It regulates the exchange of substances in and out of the cell. Cell membrane is made of 4 kinds of molecules namely phospholipids, carbohydrates, proteins and cholesterol.

Process of diffusion in which molecules pass across the membrane through cell membrane protein channels or via protein carriers.

The cell membrane, also called the plasma membrane, is a thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells, including plant and animal cells. The cell membrane, also called the plasma membrane, is a thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells, including plant and animal cells. A variety of compounds including sugars and amino acids pass through the plasma membrane and into the cell at a much higher rate than would be expected on the basis of their size, charge, distribution coefficient, or magnitude of the concentration. It contains a nucleus surrounded by a nuclear membrane.
