What else can I help you with?
Is latex a permeable membrane?
No, latex is not a permeable membrane. Latex is a type of material that is impermeable to fluids and gases, making it suitable for use in applications where a barrier is needed.
What is a good slogan for the cell membrane?
1)GO INSANE FOR THE CELL MEMBRANE! 2)I am one but part of two, I can always be found in you 3)Whats in your brain? Why its a cell membrane!
What is essential for diffusion?
A- A Concentration Gradient B- A Selectively Permeable Membrane C- A Source of Energy D- A Protein The Answer Is (A) Diffusion can occur without a semipermeable membrane, as diffusion is simply movement of a substance from high to low concentration. A source of energy is needed only for active transport. Proteins are needed if the the particles transported are too big to pass the semipermeable membrane.
In what way are cell membranes selectively permeable?
Cell membranes are selectively permeable because they allow certain substances to pass through while blocking others. This selectivity is achieved through the presence of proteins and channels that regulate the movement of specific molecules into and out of the cell. The lipid bilayer structure of the membrane also plays a role in determining which substances can cross based on their size, charge, and solubility.
What requires vesicles for transportation across cell membrane?
It is a type of active transportation.So energy is needed.
Is latex a permeable membrane?
No, latex is not a permeable membrane. Latex is a type of material that is impermeable to fluids and gases, making it suitable for use in applications where a barrier is needed.
Can you please list the conditions that are needed for effective gaseous exchange. Thanks?
A permeable membrane and a pressure differential.
What function is cell membrane?
A cell membrane is a selectivley permeable membrane. This means that it only lets specific materials get in and out of the cell. The cell membrane helps to let only needed materials into the cell and to get unneeded materials out of the cell. (food goes in waste comes out.)
What are the two things needed for osmosis to take place?
Partially permeable membrane(visking tubing) and water
Is ATP needed for osmosis?
No, ATP is not needed for osmosis. Osmosis is a passive process that occurs due to the concentration gradient of solutes across a semi-permeable membrane. ATP is required for active transport processes, not osmosis.
Why is it necessary to have a cell membrane on a plant cell?
The cell surface membrane is partially permeable membrance that is made up of double phospholid layers comprising of 1. lipids 2. fats 3. proteins 4. phosphate groups. This is therefore needed for the control of substances in and out of the cells (: margaret
What is important in osmosis which is not needed in diffusion?
In osmosis, there is a selective movement of water molecules across a semi-permeable membrane, driven by differences in solute concentration. This selectivity based on solute concentration is not a factor in simple diffusion, where molecules move freely across a membrane based on a concentration gradient without a specific solute driving the movement.

Describe the purpose of the cell membrane?
the cell membrane keeps the stuff needed inside the cell in, and the stuff needed outside the cell out
Does Osmosis require ATP?
No, osmosis does not require ATP because it is a passive process in which water molecules move from an area of higher concentration to an area of lower concentration through a selectively permeable membrane. ATP is not needed to facilitate this movement.
What is the movement of materials through the membrane called?
It's either diffusion, osmosis or active transport. More information is needed to answer the question fully.
The pressure needed to stop osmosis is called?
The osmotic pressure. This is the pressure which would have to be applied to a solution to stop water entering if it was separated from pure water by a semipermeable membrane.
