Essay questions possible essay topics for student assessment are given below they are given under describe the basic structure of a eukaryote membrane compare the channels (such as potassium channels), the gap junction channel, the nuclear pore, and the plasmodesmata of plant cells are all structures that allow hydrophilic solute to.
The main purpose of the cell membrane is to regulate the movement of materials in and out of the cell by doing so, the cell's internal environment can differ greater to the external environment, since only certain materials can pass through.
Cell membrane the cell membrane- the cell membrane is a semi-permeable membrane that surrounds the cytoplasm of a cell the cell membrane is made up of phospholipids, proteins and carbohydrates its function is to protect the integrity of the interior of the cell allowing certain substances into the cell , while keeping other substances out. The cell membrane, or the plasma membrane, is common to all cells the membrane is a thin and fragile structure, usually between 5 to 10 nm (nanometer) wide that separate cells from the science.
Because not all substances penetrate the cell membrane equally well, the membrane is known as being differentially', or selectively permeable' cell walls and membrane the main purpose of the cell membrane is to regulate the movement of materials in and out of the cell. Chapter title: membrane structure and function the ability of the cell to discriminate in its chemical exchanges with the environment is fundamental to life, and it is the plasma membrane that makes this selectivity possible.
