What else can I help you with?
What membrane that allows only some materials to move in and out of the cell is?
Such a membrane is said to be selectively permeable or semi-permeable.
What will happen if a partially permiable membrane is replaced with a non permiable membrane?
If a partially permeable membrane is replaced with a non-permeable membrane, no substances will be able to pass through the membrane. This will prevent the movement of molecules across the membrane and alter the osmotic balance between the two sides of the membrane. This could lead to changes in cell volume and affect cellular processes that rely on osmotic balance.
Why is cell membrane differentially permeable?
Selective (or differential) permeability allows the cell to regulate its internal environment and maintain internal homeostasis. This is also the basis by which a neuron (nerve cell) can 'fire' and send a message along its axon - it selectively allows one electrolyte then a different electrolyte to flow across its cell membrane and change the electrochemical gradient.
Why the line-with-gaps model is sufficient to explain the movement of materials in osmosis?
The line-with-gaps model in osmosis represents the movement of water molecules across a semi-permeable membrane from an area of high concentration to low concentration. This model simplifies the process by focusing on the movement of water only, ignoring the movement of solute particles. In osmosis, the direction of water movement is determined by the concentration gradient of water across the membrane.
Why would cell membrane be destroyed if if it were permeable instead of selectively permeable?
Unwanted substances could get in, potentially destroying the cell and membrane.
What is meant by the term differentially permeable?
differentialy permeable means, a substance which allow only certain materials to pass through it. For eg., a plant cell wall acts as a differentially permeable membrane which allow only certain materials like water, certain ions etc to pass through it.
What substance can diffuse through a differentially permeable membrane?
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
What is meant by the term differentiation?
differentialy permeable means, a substance which allow only certain materials to pass through it. For eg., a plant cell wall acts as a differentially permeable membrane which allow only certain materials like water, certain ions etc to pass through it.
What is a membrane that allows some substances to pass through but excludes others?
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
What is the Simlilarity between osmosis and reverse osmosis?
1) They both require the presence of a differentially/selectively permeable membrane/tubing. 2) They both refers to the flow of water(ONLY WATER!!!) through a differentially/selectively permeable membrane/tubing . 3) They both require energy. - They both cannot at -273.15 degree Celsius. 4) They will both reach a equilibrium and eventually stop.
HOW REVERSE OSMOSIS IS DIFFERENT FROM OSMOSIS?
1) Osmosis refers to the flow of water along the water potential through a selectively/differentially permeable membrane/tubing due to a difference in water potential. Reverse osmosis refers to the flow of water against the water potential through a selectively/differentially permeable membrane/tubing due to energy gained from the surroundings or an increase in pressure.
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
Osmosis always involves what?
Osmosis refers to the flow of water along the water potential through a selectively/differentially permeable membrane/tubing due to a difference in water potential. Thus, it always involves 1) a selectively/differentially permeable membrane 2) difference in water potential(related to concentration gradient) 3)flow of water.
What is meant by partially permeable?
a partially permeable membrane allows some molecules or ions to pass through it
What term is used to describe how the cell selects what materials enter and leave the cell?
The term is "cellular transport," which refers to the processes by which cells regulate the movement of materials across their membranes. This includes mechanisms such as passive diffusion, active transport, and facilitated diffusion.
Is the membrane permeable to protons?
Yes, the membrane is permeable to protons.
What is the transporting process for osmosis?
Osmosis is the passive movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. The process does not require energy and helps maintain the balance of water and solutes inside cells.
