Ion channels and the hydrophilic/hydrophobic/hydrophilic membrane.
Alvah Stokes
One important structure in the plasma membrane that regulates ion passage is the ion channel. These proteins form pores that allow specific ions to pass through the membrane based on their electrical charge and size. Ion channels can be opened or closed in response to various signals to control the flow of ions into or out of the cell.

Maintained by the plasma membrane is what?
the plasma membrane maintains passage of ions Homeostasis
What are the functions of the plasma membrane in Eukaryotes?
Plasma membrane gives structure to the cell, serve as boundary. It allows the selective passage of molecules across the cell (semi permeable). Starts the signalling event from the receptors it posses on the membrane surface when there is a stimuli bind to it.
What structure is involved in phagocytosis?
Plasma Membrane !
What are the specialized parts of the phospholipid bilayer and how do their structure's relate to the structure of the plasma membrane?
that meand there no plasma membrene
What property describes the plasma membrane's ability to regulate movement of molecules into and out of the cell?
permeability
Which structure regulates passage of molecules into and out of cells?
The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
What structure regulates the passage of material into and out of bacterial cell?
Cell membrane is responsible for that.It is the barrier of cell.
Maintained by the plasma membrane is what?
the plasma membrane maintains passage of ions Homeostasis
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.

What controls the passage of materials into and out of the cell?
depend on the kind of cell...... plant: cell wall and cell membrane/plasma membrane animal: cell membrane/plasma membrane
What is the bacterial structure that acts as a selective barrier allowing nutrients to enter the cell and wastes to leave the cell.?
plasma membrane
What structure is involved in phagocytosis?
Plasma Membrane !
What are the specialized parts of the phospholipid bilayer and how do their structure's relate to the structure of the plasma membrane?
that meand there no plasma membrene
Is plasma membrane premeable?
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances
What regulates a passage of materials between the cell and its environment?
cell membrane aka plasma membrane
This structure is the outermost boundary of the cell and is semipermeable?
Plasma membrane or cell membrane
