Cell Membrane Definition For Kid
The cytoplasm performs many functions to keep the cell alive.
Cell membrane definition for kid. The cell membrane is a multifaceted membrane that envelopes a cells cytoplasm. Enclosed by this cell membrane also known as the plasma membrane are the cells constituents often large water-soluble highly charged molecules such as proteins nucleic acids carbohydrates and substances involved in cellular. It is sometimes called the plasma membrane or cytoplasmic membrane.
The cell membrane plasma membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cellIts function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. The structure separating an animal cell from its environment or a plant cell from its cell wall. The cell membrane is semipermeablethat is some substances can pass through it but others cannot.
Organisms made from prokaryotic cells are very small such as bacteria. There are many types of organelles in eukaryotic cells. The chemical structure of the cell membrane makes it remarkably flexible the ideal boundary for rapidly growing and dividing cells.
Organelles typically have their own plasma membrane round them. Its basic job is to separate the inside of cells from the outside. A cell membrane is a border that covers every cell in a living organism.

It separates the cytoplasm the contents of the cell from the external environment. This characteristic enables the cell to admit or block substances from the surrounding fluid and to excrete waste products into its environment. The cell membrane is a thin flexible layer around the cells of all living things.
