What Substances that can freely dissolve through the plasma membrane are made of?
Substances that can freely pass through the plasma membrane must be small and non-polar.
What is the solubility theory of membrane permeability?
the solubility theory of membrane permeability simply describes that a membrane can only be freely permeable to substances that can dissolve in it. this was the most basic theory posed to explain how substances passed through membranes of cells. another way of explaining this is that substances that can freely or passively diffuse across membranes when they have the same chemical or physical properties as the membrane.
Do peroxisome have membrane?
Yes, peroxisomes have their own membrane. The membrane helps to keep the enzymes within the organelle from interacting freely with the other intracellular substances.
Why is it important that a cell membrane does not allow all dissolved substances to diffuse freely through it?
magnets
What term identifies the concept that some substances can move freely across a cell membrane while other substances must be carried across by proteins?
selective permeability

Do all substances pass freely between the intracellular and extracellular fluids through a phospholipid bilayer?
No, the membrane is known as semi-permeable because some substances (such as water) can pass freely through - whereas others (such as ions) cannot.
Definition of freely permeable membrane?
freely permiable membrane allows everything to pass through.
What does the cell membrane do to avoid hings going inside the cell?
Cell membrane is a Selectively Permeable Membrane so it does not allow all the substances to pass through it.It controls the movement of substances in and out of the substances.Unlike a cell membrane,the cell wall has large holes in it allowing the water and dissolved minerals to pass through hence cell wall is known as Freely Permeable Membrane.
Can oxygen diffuse across a cell membrane?
Yes, how else would our cells obtain oxygen?
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
The membrane that lines the freely movable joints is?
Synovial membrane
What does not freely diffuse through the plasma membrane?
glucose
