Your skin protects your body by forming a barrier to the outside environment.

The name of the barrier between the outside of your body and the environment is the skin. Skin acts as a protective layer that helps regulate body temperature, prevents dehydration, and serves as a physical barrier against pathogens and harmful substances.
A household item that resembles a nuclear membrane is a Ziploc bag. Just as a nuclear membrane encloses and protects the nucleus of a cell, a Ziploc bag seals and protects its contents from the outside environment. Similarly, a refrigerator door acts as a barrier, maintaining a controlled environment for the food inside, akin to how a nuclear membrane regulates what enters and exits the nucleus.
The skin is the boundary which separates an organism from its environment. But this barrier that keeps you on the inside and the germs on the outside must also allow certain exchanges between the organism and the environment, for survival.
The cell wall is the barrier of the cell and protects it from danger outside the cell. It also gives the cell a structure.
The cell membrane
Yes, the cell membrane forms a barrier with the outside environment. It is a selectively permeable membrane that regulates the movement of substances into and out of the cell, allowing some molecules to pass through while keeping others out. This helps to maintain the internal environment of the cell.
The integumantary system consists of skin. hair, and finger nails. The main aspect of this system involves the skin. The primary function is to maintain a barrier between the body and the outside environment. This barrier prevents virus's and bacteria from entering the body; furthermore, this system aides in maintaining water and other fluids inside the body. Lastly, the integumentary system protects organs from damage.
The structure that covers the cell and acts as a barrier to the outside environment is the cell membrane, also known as the plasma membrane. It is composed of a phospholipid bilayer with embedded proteins that facilitate selective transport of substances. This semi-permeable nature allows certain molecules to move in and out while keeping others contained, thus maintaining the internal environment of the cell.
The cell membrane acts as a barrier between a cell and its environment. This is composed of a phospholipid bilayer. The hydrophilic phosphate heads face outside and the hydrophobic lipid tails point towards each other in the centre of the membrane.
The plasma membrane is the organelle that protects the animal cell from the outside world. It controls the movement of substances in and out of the cell and helps maintain the cell's internal environment.
