2025年1月15日 · Cell membrane, thin membrane that surrounds every living cell. The cell membrane functions as a barrier, keeping cell constituents in and unwanted substances out, and as a gate, allowing transport into the cell of essential nutrients and movement from the cell of waste products.

2023年2月2日 · 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.

2023年8月3日 · In the plant cells, it is known as plasmalemma. The term cell membrane was given by Nageli and Cramer (1885) for the membrane covering of the protoplast. There are two types of cell membrane. They are: Cytoplasmic membrane: which surrounds the whole protoplasm. Internal membrane: which surrounds various cellular organelles and vacuoles.

2020年10月19日 · The cell membrane gives the cell its structure and regulates the materials that enter and leave the cell. It is a selectively permeable barrier, meaning it allows some substances to cross, but not others.

The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space). [1][2] The cell membrane consists of a lipid bilayer, made up of two layers of ...

2023年7月18日 · Cell membranes are responsible for a variety of important functions within the body, such as allowing control of the enclosed environment. In this article we shall consider the main functions of the cell membrane, the composition of membranes and clinical conditions in which a portion of the cell membrane is abnormal.

2024年6月7日 · The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out.

2024年10月25日 · The architecture of the cell membrane involves multiple components working together. Exploring these elements reveals their specific roles and interactions within the cellular landscape.

2024年5月16日 · The cell membrane, also known as the plasma membrane, is a thin, semi-permeable barrier that surrounds and encloses the contents of a cell. It separates the interior of the cell from the external environment, protecting the cell and regulating the movement of substances in and out of the cell.

2023年10月15日 · The cell membrane, also known as the plasma membrane, is a complex biological structure that surrounds and encapsulates all living cells. As the selective barrier between a cell’s interior and the outside environment, the cell membrane controls the movement of materials in and out of the cell and facilitates cellular processes essential for life.
