The cell membrane, also known as the plasma membrane, is a protective barrier that surrounds a cell, maintaining its integrity and regulating the movement of substances in and out. Composed mainly of a phospholipid bilayer with embedded proteins, it plays a crucial role in communication and signaling between cells. The membrane's selective permeability allows it to control the internal environment, facilitating essential processes like nutrient uptake and waste removal. Overall, it is vital for maintaining homeostasis within the cell.
What else can I help you with?
What part of the cell is enclosed by it own membrane?
The nucleus is the part of the cell that is enclosed by its own membrane, known as the nuclear membrane or nuclear envelope. This membrane separates the nucleus from the cytoplasm of the cell and helps regulate the movement of molecules in and out of the nucleus.
Can steriods and cholesterol cross the cell membrane on their own?
Yes because the cell membrane allows non polar molecules through
What manufactures cellular membranes by adding membrane proteins and phospholipids to its own membrane?
The endoplasmic reticulum manufactures cellular membranes by adding membrane proteins and phospholipids to its own membrane. This process helps in the production and maintenance of cell membranes throughout the cell.
Is a cell membrane living or non living?
The cell membrane is considered non-living, as it is composed of lipids and proteins that do not have the characteristics of living organisms, such as the ability to reproduce or metabolize. It acts as a barrier that separates the cell from its environment and helps regulate the passage of substances in and out of the cell.
What Controls what moves in and out of the cell?
Cell membrane
What part of the cell is enclosed by it own membrane?
The nucleus is the part of the cell that is enclosed by its own membrane, known as the nuclear membrane or nuclear envelope. This membrane separates the nucleus from the cytoplasm of the cell and helps regulate the movement of molecules in and out of the nucleus.
What is a sentence that uses the words cell membrane?
The cell membrane is selectively permeable.
What are two words for cell wall?
Cell membrane and Cell wall are about it.
What is the structure of a generalized eukaryote cell?
Cytoplasm (inside a cell membrane) surrounding a nucleolus (which is inside its own membrane).
Can you give me a sentence using the word cell membrane?
A plant cell has a cell membrane and a cell wall.
Can steriods and cholesterol cross the cell membrane on their own?
Yes because the cell membrane allows non polar molecules through
What manufactures cellular membranes by adding membrane proteins and phospholipids to its own membrane?
The endoplasmic reticulum manufactures cellular membranes by adding membrane proteins and phospholipids to its own membrane. This process helps in the production and maintenance of cell membranes throughout the cell.
Do viruses have a nuclear membrane a cell wall membrane-bound organelles or ribosomes?
No, viruses do not have membrane bound organalles

What Controls what moves in and out of the cell?
Cell membrane
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.
