The plasma membrane is selectively permeable, allowing certain molecules to travel in and out of the cell. The size, PH, and temperature all play a factor in what molecules travel through the membrane or don't.

What is the characteristic of a cell membrane that controls which substances that can either enter and exit the cell?
Selective permeable
What structure acts as a selective barrierregulating the traffic of materials into and out of the cell?
Cytoplasm is the selectively permeable structure that separates intracellular material from extracellular material.
What property of the cell membrane allows it to maintain cell homeostasis?
Selective Permeability
What is cytoskeletons job in the cell?
It determines the shape of the cell.
Selective permeability refers to the fact that the plasma membrane keeps all molecules out of the cell?
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.
How is lipids suited to the function of the membrane?
It separates the cell from its surroundings and acts as a selective barrier to the passage of substances in and out of the cell
A membrane at the boundry of every cell that acts as a selective barrier?
The membrane at the boundary of every cell that acts as a selective barrier is called the cell membrane. The cell membrane is made of compounds called proteins and lipids.
What is the roll of the cellmembrane?
It protects the cell from outside forces. The cell membrane works as a selective filter that allows only certain things to come inside or go outside the cell.
What is a selective barrier regulating the passage of materials into and out of the cell?
In a plant cell, this selective barrier is known as the cell membrane but also a plant cell has a cell wall. The cell membrane is semi permeable allowing only certain materials so the cell membrane allows in materials and the cell wall ''digests it''. While in a plant cell does not have a cell wall only a cell membrane.It is the cell membrane that acts as its selective barrier.
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 is the characteristic of a cell membrane that controls which substances that can either enter and exit the cell?
Selective permeable
How are lipids suited to the functions of the membrane?
the outer boundary of the cell. It separates the cell from its surroundings and acts as a selective barrier to the passage of substances in and out of the cell.
Cells are bounded by which structure which separates the inside of the cell from the outer environment and which acts as a selectivesemi-permeable filter for the cell?
"membrane"
Which part of the cell allows for selective permeability?
Cell membrane
What is the cell wall's purpose in a plant cell?
A cell wall basically acts as an extra layer of protection for the cell: while animal cells only have cell membranes, a plant cell has a cell membrane with a cell wall around it. It also provides the cell with structural support and acts as a pressure vessel which is basically a filter that stops over-expansion when water enters the cell.
What is the cell membrane what does it do for the cell and what is it made of?
The cell membrane acts as the walls, floor and ceiling or covering that surrounds the cell and determines what is "inside" the cell and what is "outside". It is made of a lipid bilayer (two layers) of lipoproteins (fats+proteins). These are very fluid and to make it steadier cholesterol molecules are imbedded in it. There are also proteins in the membrane that acts as doors or windows. They allow some things in and out.
What is the part of the cell that determines the cell's activity?
The nucleus regulates the cell's activities, because it controls what the cell does, what comes inside the cell and leaves the cell. It acts like the 'brain' of the cell.
