What is a characteristic of cell membranes?Answer this question…
selective permeability
A characteristic of a cell undergoing apoptosis is the condensation of chromatin and fragmentation of the nucleus, leading to the shrinkage of the cell. This process often includes the formation of membrane-bound vesicles called apoptotic bodies, which are eventually engulfed and cleared by neighboring cells or immune cells. Additionally, there is a characteristic change in the cell membrane, such as the externalization of phosphatidylserine, signaling for phagocytosis.
Animal cells have a cell membrane; plant cells have both a cell membrane and a cell wall. Thus bacteria are plants.
The cell membrane acts as a barrier, controlling the entry and exit of substances into and out of the cell. It is composed of a phospholipid bilayer with embedded proteins that help in cell recognition, cell signaling, and transport of molecules. The cell membrane is selectively permeable, allowing only specific substances to pass through.
The selective permeability, also called semi-permeability, of the membrane controls which substances cant enter and exit the cell.

the chemical nature of the membrane
The fluid mosaic model describes the cell membrane as a fluid structure where lipids and proteins are able to move around and change position. This constant shifting allows the cell membrane to maintain flexibility and adapt to changing conditions.

Selective permeability is the characteristic of the cell membrane that allows only certain molecules and ions to enter or exit the cell. This feature helps regulate the internal environment of the cell by controlling what substances can pass through.
A characteristic of Animal cells is that they have cell membrane and no cell wall (like plant cells)
