The cell membrane controls the passage of substances into and out of the cell. It is a selectively permeable barrier made up of a phospholipid bilayer with proteins embedded in it. It allows some material (such as steroid hormones) to pass straight through, while others (such as ions) need the assistance of a protein transporter, and some material cannot get in at all.
What else can I help you with?
What controls the passage of nutrients in and out of the cell?
The cell membrane controls what enters and exits a cell.
What controls the passage of material into and out of cells?
The cell membrane controls the passage of substances into and out of the cell. It is a selectively permeable barrier made up of a phospholipid bilayer with proteins embedded in it. It allows some material (such as steroid hormones) to pass straight through, while others (such as ions) need the assistance of a protein transporter, and some material cannot get in at all.
Which cell part that controls the passage of nutrients into the cell?
the cell membrane
What separates the intracellular material from the extracellular material?
The cell membrane, also known as the plasma membrane, separates the intracellular material from the extracellular material. This selectively permeable barrier controls the passage of substances in and out of the cell, helping to maintain cellular homeostasis.
Holds cell material inside and controls flow of material in and out?
The cell membrane.
What part of cell controls material going in and out of the cell?
Cell membrane.
Which cell structure contains the cell's genetic material and controls the cell's activities?
The nucleus controls the cells activities
What does a cell wall for do a cell?
the cell wall-offers protection to a cell -allow material passage
What controls the passage of nutrients into the cell and wastes out of the cell?
The plasma membrane controls the passage of nutrients into the cell and wastes out of the cell through a process called selective permeability. This involves transport proteins and channels that regulate the movement of molecules based on size, charge, and concentration gradients.
What cell forms a barrier that controls passage of molecules or forms glands?
Epithelial
What is the material called that controls the cell activities?
DNA
What is the meaning of pylorus?
The ring of muscle that controls the passage of material from the stomach into the small intestine.
