What is within the cell wall?A. Another oneB. ArchaebacteriaC. Cell membraneD. Pili
Within the cell wall, the correct answer is C
Within the cell wall, the correct answer is C. Cell membrane.
The cell wall is a rigid outer layer that is found in many organisms, including plants, bacteria, fungi, and some archaea. The main function of the cell wall is to provide structural support and protection to the cell.
Within the cell wall, there is a thin layer called the cell membrane, also known as the plasma membrane. The cell membrane is a semi-permeable barrier made up of phospholipids and proteins. It surrounds the cytoplasm and separates the internal cellular environment from the external environment.
The cell membrane plays a crucial role in maintaining the integrity of the cell. It regulates the movement of molecules in and out of the cell, allowing certain substances to enter or leave while restricting others. This process is known as selective permeability.
In addition to its role in maintaining cellular integrity, the cell membrane is also involved in various important cell functions. It serves as a boundary for cell communication, allowing cells to send and receive signals with the external environment and with other cells. The cell membrane contains receptors and channels that facilitate cell signaling and cellular transport.
In summary, within the cell wall, you will find the cell membrane, which acts as a protective barrier and regulates the movement of substances in and out of the cell.
