The tonoplast is called selectively permeable because it allows only certain substances to pass through, while blocking others. This selective permeability helps maintain the internal environment of the vacuole by controlling the movement of ions, nutrients, and waste in and out of the vacuole.
What else can I help you with?
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
Why is the plasma membrane called a selectively permeable membrane?
The Plasma Membrane is a selectively permeable membrane as it only allows entry and exit of some selected molecules into and out of the Cells. It also prevents movement of some other materials, therefore the plasma membrane is called a selectively permeable membrane.
What is the structural model of the plasma membrane called-?
structural model of plasma membrane is called the selectively permeable membrane Structural model of the plasma membrane is called Fluid Mosaic Model.
Cell membranes that allow certain molecules to pass through while keeping others out are called?
semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable
What process occurs as water moves from regions of higher water concentration to regions of lower water concentrtion across a selectively permeable membrane?
The process that occurs is called osmosis. Water molecules move through the selectively permeable membrane to even out the concentration of water on both sides of the membrane. This continues until the concentration of water is equal on both sides.
A membrane that allows some substances to pass through while excluding others would be called a?
semipermeable or selectively permeable.

What is it called that all cells have that allow them to let materials in and out?
selectively permeable membrane.
What is a membrane called when only certain things can cross a membrane?
A membrane that only allows certain substances to cross is called a selectively permeable or semi-permeable membrane. It allows some molecules or ions to pass through while blocking others based on characteristics like size, charge, or solubility.
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.
The diffusion of water across a selectively permeable membrane through aquaporins is called?
osmosis
What is the name of the membrane that surrounds the vacuole?
It is called the vacuolar membrane.Sometimes it is referred to as the vacuole membrane. The membrane round the large central vacuole in plants it is also called the tonoplast.
The passive transport of water across a selectively permeable is called?
The passive transport of water across a selectively permeable membrane is called osmosis. Osmosis involves the movement of water molecules from an area of higher concentration to an area of lower concentration, in order to equalize the solute concentrations on both sides of the membrane.
What is the movement of water through a selectively permeable membrane?
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
