What else can I help you with?
The plasma membrane would fit into which general function category?
The plasma membrane would fit into the general function category of "barrier protection and selective permeability." It serves as a barrier to separate the inside of the cell from the external environment while selectively allowing certain substances to pass through.
What acts as a gatekeeper to certain substances from entering brain tissue?
The blood-brain barrier acts as a gatekeeper to certain substances from entering brain tissue. It is a protective membrane that separates the blood vessels in the brain from the surrounding fluid, preventing the passage of many harmful substances while allowing essential nutrients and oxygen to reach the brain. This barrier helps maintain the delicate balance required for optimal brain functioning.
Cell membrane structure describe?
The cell membrane is a phospholipid bilayer that surrounds the cell, providing a barrier between the cell's internal environment and the external environment. It is selectively permeable, allowing only certain substances to pass through. Proteins embedded in the membrane help with various functions such as transport, communication, and signaling.
What areThe cells of the nervous system that form the bloodbrain barrier that keeps certain substances from gaining access to the brain are called?
The cells of the nervous system that form the blood-brain barrier are called endothelial cells. These cells help regulate the passage of substances between the bloodstream and the brain to protect the brain from harmful substances and maintain a stable environment for proper brain function.
Mary discovered that the cell membrane of a bacteria acts like a fence because it keeps some things in and other things out?
Yes, the cell membrane of bacteria acts as a selective barrier, allowing certain molecules to enter and exit the cell while preventing others from doing so. This helps the cell maintain its internal environment and regulate what substances can pass through.
Regulates interaction between the cell and its environment is what?
The cell membrane regulates the interaction between the cell and its environment. It acts as a selectively permeable barrier, allowing certain substances to enter or exit the cell while restricting others. This helps maintain cellular homeostasis and ensures proper communication with the external environment.

What is a semi-permeable membrane and how does it regulate the passage of substances in and out of cells?
A semi-permeable membrane is a barrier that allows certain substances to pass through while blocking others. It regulates the passage of substances in and out of cells by selectively allowing molecules based on their size, charge, and solubility. This helps maintain the cell's internal environment and allows for essential processes like nutrient uptake and waste removal.
What is the barrier around the that lets substances move across it?
Cell membrane is the barrier around the cell that allows certain substances to move across it. It is selectively permeable, meaning it controls the movement of molecules in and out of the cell. This helps maintain the internal environment of the cell and ensures proper functioning.
Which is responsible for providing a barrier allowing only certain things in and out of the cell?
Cell membrane
Which organelle is responsible for a barrier allowing only certain things in and out of the cell?
Cell membrane
What part of the cell receive incoming messages?
The cell membrane receives incoming messages from the external environment. It acts as a barrier that allows certain substances to enter or exit the cell, enabling communication with the outside environment.
What is the part of the cell that materials pass through?
Materials pass through the cell membrane, which acts as a barrier between the cell's interior and the external environment. The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.
What part of the cells acts as a barrier t ocontrol what enters and leaves the cell?
The cell membrane acts as a barrier to control what enters and leaves the cell. It is selectively permeable, allowing certain substances to pass through while blocking others.
