The cell membrane - the outer layer in animal cells and the layer beneath the cell wall in plants that is made up of a double layer of phospolipid molecules. The term semipermeable means that the outer layer only allows certain substances into and out of the cell, not everything.
What else can I help you with?
What is the cell structure that is located in the external boundaries of the cell?
The cell structure that is located in the external boundaries of the cell is the cell membrane. The cell membrane is a semipermeable membrane composed of lipids and proteins that surrounds the cell, providing a barrier between the cell's interior and its external environment.
Which structure in an onion epidermal cell is semipermeable?
The cell membrane is the semipermeable structure in an onion epidermal cell. It regulates the passage of molecules in and out of the cell, allowing only certain substances to pass through while restricting others.

Scientific definition of cell membrane?
The cell membrane, also known as the plasma membrane, is a semipermeable barrier that surrounds the cell, separating its internal environment from the external environment. It consists mainly of lipids and proteins, and regulates the passage of substances in and out of the cell, ensuring its survival and functioning. The lipid bilayer structure of the cell membrane provides flexibility and fluidity, allowing the cell to maintain homeostasis and respond to changes in its surroundings.
What does plsma membrane do?
The plasma membrane is a semipermeable barrier that surrounds the cell, regulating the movement of substances in and out of the cell. It also plays a crucial role in cell communication and recognition of other cells. Additionally, the plasma membrane helps maintain the cell's structure and shape.
This structure is the outermost boundary of the cell and is semipermeable?
The structure you are referring to is the cell membrane, also known as the plasma membrane. It surrounds the cell, acts as a barrier, and regulates the passage of substances in and out of the cell through selective permeability.
What is the cell structure that is located in the external boundaries of the cell?
The cell structure that is located in the external boundaries of the cell is the cell membrane. The cell membrane is a semipermeable membrane composed of lipids and proteins that surrounds the cell, providing a barrier between the cell's interior and its external environment.

the cell membrane
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
What is the Difference between plasmamembrane and cell membrane?
The terms "plasma membrane" and "cell membrane" are often used interchangeably to refer to the same structure. Both terms refer to the semipermeable lipid bilayer that surrounds the cell and controls the movement of substances in and out of the cell.
