It lacks all membrane bound cell organelles such as mitochondria, lysosome, golgi, endoplasmic reticulum, chloroplast, peroxisome, glyoxysome, and true vacuole. Cell Membrane - semi-permeable membrane that forms the boundary of the cell and controls what comes in andgoes out of the cell. Structure of Plasma Membranes The primary function of the plasma membrane is to protect the cell from its surroundings. Life is an orderly thing, and biological membranes maintain the order by dividing cellular spaces into functional units with their own specific content. Types of cell junctions. In our model of scale, that the cruise ship represented the cell. About 52% of the membrane mass is protein, 40% is lipid, and 8% is carbohydrate. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. It is safe to say that proteins give the membrane and the cell it surrounds a character. 1. Cell membrane structure.

This is a good introduction to a cell unit. These cell organelles can be found in both membrane-bound organelles and non-membrane organelles. Animal cells are the basic structural and functional unit of life of the animals. The main lipid components are phospholipids, which vary in acyl chain length, saturation, and branching and carry head groups that vary in size and charge. They are all artistically enhanced with visually stunning color, shadow and lighting effects. In plant cells, the membrane encapsulates the protoplasm. &and functions 1.
