Which organelle is responsible for providing a barrier allowing only certain things in and out of the cell?
The Plasma Membrane
The Plasma Membrane. The plasma membrane forms a barrier between the cytoplasm inside the cell and the environment outside the cell. It protects and supports the cell and also controls everything that enters and leaves the cell. It allows only certain substances to pass through, while keeping others in or out.
What is a flexible barrier that lets particles in and out of a cell?
All cells are surrounded by a thin, flexible barrier known as the cell membrane. The cell mem- brane is sometimes called the plasma membrane because many cells in the body are in direct contact with the fluid portion of the blood—the plasma.
What organelle allows materials in and out of the cell?
The plasma membrane is the outer lining of the cell. It separates the cell from its environment and allows materials to enter and leave the cell. Ribosomes. Ribosomes are organelles that process the cell’s genetic instructions to create proteins.
Which organelle serves as a barrier between the inside of a cell and the outside world?
The cell membrane is a protective layer that covers the cell’s surface and acts as a barrier between the inside of a cell and the cell’s environment. The cell membrane also controls materials going in and out of the cell.
What is flexible barrier that protects the inside of a cell?
cell membrane
Also, all cells are surrounded by a thin flexible barrier called a cell membrane.
Which organelle looks like a flexible skin?
The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle.
