The cell membrane
Plasma (Cell) Membrane
Cell (Plasma) Membrane
The cell membrane controls what enters or leaves the cell.
The three main parts of a cell are the cell membrane, which acts as a barrier and controls what enters and exits the cell, the cytoplasm which contains organelles and where many cell processes occur, and the nucleus which houses the cell's genetic material (DNA).
The entrance of the restaurant can be compared to the cell membrane of a cell. Just like the cell membrane regulates what goes in and out of the cell, the entrance of a restaurant controls who enters and exits the establishment. It serves as a barrier that separates the inside and outside environments.
The cell membrane is the part of the cell that controls what enters and leaves the cell. It allows nutrients to come in and wastes to move out.
The nuclear membrane also plays a role in regulating what enters and exits the nucleus, similar to the nucleolus.
Just as a school building controls what enters and exits the premises, the cell membrane encloses the cell and regulates the passage of substances in and out. Both act as a barrier providing protection and maintaining internal conditions.
The cell membrane, also known as the plasma membrane, regulates what enters and exits a cell. It is selectively permeable, allowing certain molecules to pass through while blocking others. Transport proteins embedded in the membrane control the movement of substances in and out of the cell.
The cell membrane, also known as the plasma membrane, controls what goes in and out of the plant cell. It is a selectively permeable barrier that regulates the passage of nutrients, ions, and waste products.
Nucleus: the control center of the cell that contains genetic material (DNA) and regulates cell activities. Cytoplasm: a jelly-like substance inside cells that contains organelles and where many cellular processes occur. Cell surface: the outer boundary of the cell that controls what enters and exits the cell.
Each part of an animal cell has a specific function: Cell membrane: surrounds the cell and controls what enters and leaves. Nucleus: contains DNA and controls the cell's activities. Mitochondria: produce energy for the cell. Endoplasmic reticulum: involved in protein and lipid synthesis. Golgi apparatus: processes and packages proteins for transport.
