What else can I help you with?
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
What is the thin flexible membrane around all cells?
the cell membrane is as flexible barrier outside of the cell.
What is the outer boundary of a cheek cell called?
cell surface membrane cell surface membrane
The outermost boundary of an animal cell is the?
the cell membrane
What regulates passage of materials into and out of cells?
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
Define the structure and function of the cell membrane plasma membrane?
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.
Define When a cell use energy to move material across cell membrane?
if it is against a concentration difference.
What is the function of the carbohydrates that stick out if the plasma membrane?
The carbohydrates help identify chemical signals and define the characteristics of the cell.
How do you define eukaryote?
A eukaryote is an organism with cells with a nucleus and other organelles enclosed within a cell membrane.
Define a cell?
smallest unit that displays the properties of life; always contains cytoplasm surrounded by a plasma membrane.
Is the Cell membrane considered to be a part of the Cell's protoplasm?
The cell membrane is made of neither protoplasm nor cellulose.The cell membrane is mostly composed of molecules called phospholipids - which have a phosphate head and a lipid tail.The cell wall of plant cells (which is different to the cell membrane) is made mostly of cellulose.Protoplasm refers to all the living contents of a cell (which are surrounded by the cell membrane).
What Controls what moves in and out of the cell?
Cell membrane

What is the thin flexible membrane around all cells?
the cell membrane is as flexible barrier outside of the cell.
What controls the entering and leaving of a cell?
cell (plasma) membrane
Which contains the other cell membrane or phospholipid?
the cell membrane
What is a Prokaryotics cells?
One with no nucleus, or complex organelles
