What is the part of the cell that materials pass through?
The membrane
What allows some materials to pass through it but keeps other materials out?
membrane
What are the process in which materials move through a cell membrane?
diffusion and osmosis
How does the structure of the plasma membrane allow materials to move across it in both directions?
The structure of the plasma membrane consists of the phospholipid bilayer, which gives it a fluid structure, and not rigid, allowing the materials ease to pass through. Next, there are also integral proteins which can be thought of as 'tunnels', allowing the materials to come in and out. Then, there are peripheral proteins which also aid in getting the materials inside an out. On the cell membrane, there are receptors which recognize outside materials, and if they are really big, the cell engulfs these molecules through endocytosis [pinocytosis, and phagocytosis, which are basically for liquid molecules, and solid molecules]. This takes us back to the fluidity of the cell membrane. That's roughly how the cell membrane allows for the entering and exiting materials.
How can cell membrane act like a bouncer?
The cell membrane is semipermeable, so as a bouncer at a club the membrane does not allow all substances through it's surface.
What does the rate at which materials move through the cell membrane depend upon?
the cell's surface area
What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
How do most materials etner cells?
Through proteins in the membrane.
What is the part of the cell that materials pass through?
The membrane
What materials go in and out of an organism's cells through?
The cells go through the cell's membrane
Do materials move into the nucleus do pores in the nuclear membrane?
Yes, materials move into the nucleus through pores in the nuclear membrane.
What allows some materials to pass through it but keeps other materials out?
membrane
What Materials enter and leave the cell through openings in its?
Cell Membrane
Why are cellular transport and cellular communication factors that limit cell size?
The cellular transport and cellular communication factor that limit the cell size because all the materials that go in and out of a cell must pass through the plasma membrane.
How do materials enter and leave the nucleus?
Materials enter and leave the nucleus through the selective membrane. The membrane always controls what leaves and enters the nucleus.
A membrane that allows some but not all materials to pass through it is called .?
This sort of membrane is said to be semipermeable.
What are the special structures in the membrane that allow materials as water and sugar to pass through made of?
Membrane transporter.
