If you break down the two words, selective means to only pick certain things, and permeable means to let pass through.
When you talk about something being "selectively permeable", it usually refers to a cell membrane because it only lets in certain nutrients and lets out proteins and what not.
I hope this answers your question.

non-permiable is when nothing can pass though ex. a glass wall can't let gas of liquid through

Define selectively permeable?
A selectively permeable membrane only allows certain material to pass through it. They do so through active or passive transport.
Define the term osmosis?
osmosis - Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration
Define between plant cell and animal cell?
A plant cell has a nucleus, cytoplasm, cell wall, cell membrane and (most of the time) chloroplasts. An animal cell only has a nucleus, cytoplasm and cell membrane.
In terms of filtration define selectivity?
In terms of filtration, selectivity is a parameter. It is 1 of 2 factors that determines how successful the membrane filtration process was.
What is cell membrane define?
every living cell is surronded byu a living membrane called cell membrane which allows the passage of some molecules preventing the passage of others in this way maintains the internal composition to constant or nearly constant.
Define selectively permeable?
A selectively permeable membrane only allows certain material to pass through it. They do so through active or passive transport.
How do you define osmosis?
Osmosis is the movement of water across a selectively permeable membrane in a response to gradients of concentration, pressure, or temperature. I got this from my Biology textbook.
Define the term osmosis?
osmosis - Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration
What is the define of vacuoles?
Membrane-bound sacs that are filled with fluid.
How is osmosis related to solution types?
We define Osmosis as the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. It means that Semi permeable membrane is a very thin layer of material which allows some molecule to pass through them and prevent some molecule from pass through them. These molecules are decided by the type of solution. Generally, the membrane only allows movement of H2O molecules. So, if on one side is a saturated solution of something while on the other side is a dilute solution, the movement of molecules will be from both the directions but net result will be from saturated to dilute solution.
What is the easiest way to define osmosis?
The movement of water across a semipermeable membrane.
How do you define term membrane transport?
Membrane transport is the collection of mechanisms that regulate the passage of solutes and small molecules through biological membranes.
Define the structure and function of the cell membrane plasma membrane?
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.
Define osmosis and diffusion?
Osmosis is the random movement of particles across (through) a partially permeable membrane along a concentration gradient from an area of high concentration to an area of low concentration. Diffusion is the random movement of particles in a solution from an area of high concentration to low concentration. Eventually the particles will be uniformly and randomly distributed.
What is the function of the carbohydrates that stick out if the plasma membrane?
The carbohydrates help identify chemical signals and define the characteristics of the cell.
Define When a cell use energy to move material across cell membrane?
if it is against a concentration difference.
How do you define eukaryote?
A eukaryote is an organism with cells with a nucleus and other organelles enclosed within a cell membrane.
