What else can I help you with?
Which structure is responsible for allowing materials into and out of an animal cell?
The cell structure which is primarily concerned with the diffusion of materials into and out of cells is the cell membrane. This is made possible by the semi-permeable membrane.
Where diffusion occur?
Diffusion occurs on the cell membrane.
How does the cell membrane structure is design and explain how that helps keep water from leaving the cell?
osmosis and diffusion. i hope this answers your question. :)
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
Can phospholipids move laterally along the plane of the membrane?
Yes, phospholipids can move laterally along the plane of the membrane. This movement is known as lateral diffusion and it allows for flexibility in the structure of the cell membrane. Lateral diffusion is influenced by factors such as temperature and composition of the membrane.
What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
What cell part plays a role in diffusion?
The plasma membrane of a cell plays a role in diffusion.
What does diffusion do in a cell?
Move things across the cell membrane.
What structure regulates what enters a leaves a cell?
The structure that regulates what enters and leaves a cell is the cell membrane, also known as the plasma membrane. It is primarily composed of a phospholipid bilayer with embedded proteins that facilitate transport. This selective permeability allows the membrane to control the movement of substances, maintaining the internal environment of the cell. Additionally, various transport mechanisms, such as passive diffusion, facilitated diffusion, and active transport, play crucial roles in this regulation.
What is faciillitated diffusion?
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
