Which structure of a root hair cell controls the uptake of nitrate ions into the cell?
The cell membrane of a root hair cell controls the uptake of nitrate ions into the cell. Specifically, the transport proteins embedded in the cell membrane facilitate the movement of nitrate ions into the cell through processes like active transport or facilitated diffusion.
What is the propose of the cell membrane?
The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
Controls the movement of molecules into and out of the cell?
To put it simply, it is the cell membrane. You can have transport vesicles ect, but the cell membrane is the main barrier between inside and outside. It contains pumps, channels and proteins that are in charge of communication and also control movement of everything from inside and outside. hhh
What cell organelles is made mostly of fats and proteins and controls substances moving in and out of the cell?
The cell membrane is made mostly of fats and proteins, and it controls the movement of substances in and out of the cell by acting as a selectively permeable barrier. It regulates the passage of ions, molecules, and other substances to maintain the internal environment of the cell.
What controls the passage of molecules in and out of the cell?
Cell membrane controls the passage of molecules in and out of the cell through selective permeability. This allows specific molecules to pass through while preventing others from entering or exiting the cell. The cell membrane contains protein channels and pumps that regulate the movement of ions and molecules.

What controls movement of materials in and out of the cell?
The cell membrane regulates the movement of materials in and out of the cell through processes such as diffusion, osmosis, and active transport. Additionally, specific transport proteins embedded in the membrane facilitate the passage of certain molecules and ions.

Which part of the plant cell controls what goes in and out of the cell?
The cell membrane, also known as the plasma membrane, controls what goes in and out of the plant cell. It is a selectively permeable barrier that regulates the passage of nutrients, ions, and waste products.
The outer covering of a cell that controls what enters and leaves is called the?
The outer covering of a cell that controls what enters and leaves is called the cell membrane. It acts as a barrier to regulate the passage of molecules and ions in and out of the cell.
Which cell structure controls the movement of materials into and out of the cell?
M for membrane I would suppose.
Which structure is in both plant cells and animal cells controls the passage of substances into and out of cells?
The cell membrane is the structure found in both plant and animal cells that controls the passage of substances into and out of cells. It is a selectively permeable barrier that regulates the movement of molecules such as nutrients, ions, and waste products.

How does the process of ion exchange in the cell membrane involve the movement of 2 potassium ions in and 3 sodium ions out?
Ion exchange in the cell membrane involves the movement of 2 potassium ions into the cell and 3 sodium ions out of the cell through specific protein channels. This process helps maintain the cell's internal balance of ions, which is crucial for proper cell function.
What are three ways the cell membrane helps a cell stay balanced?
The cell membrane controls the movement of substances in and out of the cell, maintaining an internal balance of ions and molecules. It also helps in communication between cells by interacting with external signaling molecules. Additionally, the cell membrane provides structural support and shape to the cell.
