A permeable substance is a material that allows liquids or gases to pass through it. This can include materials like certain fabrics, membranes, or porous rock that enable the flow of fluids or gases. Permeable substances are often used in filtration systems or to control the movement of substances in various applications.

When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
What substance can diffuse through a differentially permeable membrane?
Substances such as water, gases (like oxygen and carbon dioxide), and small molecules (like glucose and amino acids) can diffuse through a differentially permeable membrane. The ability of a substance to pass through the membrane depends on its size, charge, and concentration gradient.
What does it mean to be selectively permeable semi-permeable?
Being selectively permeable or semi-permeable means that a membrane allows some substances to pass through while restricting the passage of others based on size, charge, or other properties. This selectivity enables the membrane to regulate the movement of molecules and ions in and out of cells or compartments, maintaining homeostasis and enabling essential biological processes.
Is cell wall is a permeable membrane?
No, the cell wall is not a permeable membrane. It acts as a rigid structure that provides support and protection to the cell, allowing certain substances to pass through pores, but it is not freely permeable like a membrane.
Is the cell membrane selectively permeable?
Yes, the cell membrane is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This property helps regulate the movement of ions and molecules in and out of the cell, maintaining cellular homeostasis.
What word means a substance that lets water through is it impermeable permeable souble or insoluble?
permeable
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
What is it called when a substance can not pass through the cell membrain?
Selectively Permeable
If a membrane was not permeable to sugars why would it probably also not be permeable to starch molecules?
If a membrane is permeable to a substance, it means that there are gaps/holes/pores in the membrane large enough for that substance to pass through. Starch molecules are bigger that sugar molecules. So if the membrane is not permeable to sugars, the gaps/holes/pores will not be big enough for starch molecules to pass through either.
If a substance is able to diffuse across a membrane then the membrane is said to be what?
selectively permeable
What is the membrane said to be if a substance is able to diffuse across a membrane?
selectively permeable
What is the characteristic of a cell membrane that control which substance can enter and exit the cell?
Selective permeable
What is a characteristic of a cell membrane that controls which substance can enter and exit the cell?
Selective permeable
What is the characteristic of cell membrane that controls which substance can enter and exit the cell?
Selective permeable
What is the characteristic of a cell membrane that controls which substance can enter and exits the cell?
Selective permeable
What kind of membrane is where some substance can pass through and others can't?
semi-permeable membraneHope it helped :)
What does permeamble mean?
A Permeable Substance has pores or openings that permit materials (liquid, gas, etc.) to pass through.
