Marble is stone that is generally polished and used in fine building work, furniture, or decorative art. It may be white or colored. It is porous, and easily stained. Marble is etched by acids. Wipe off anything spilled on marble immediately, as you would on a wood surface. Avoid setting beverage glasses directly on marble as they leave rings.
Plasma membranes are selectively permeable.
permeable
Impermeable rocks cause more rapid run off than permeable rocks. This is because the water can somewhat flow through the permeable rocks, not impermeable ones.
A rock that has high porosity is not permeable if the pores or fractures are not connected. The larger and better shorted the particles are, the more permeable the rock or sediment tends to be. Because of this characteristic composition, clay is essentially impermeable, which means that water cannot flow through it.
Impermeable means water can't get through it. For example, clay is impermeable substance (because water can't seep through it), but chalk is permeable (because water can drip through it slowly) Sometimes it also applies to places which you can't get into, for example, an 'impermeable fortress' would be difficult to get into.
the cell wall is fully permeable
if it is permeable yes impermeable no
semi permeable lets some substances through and impermeable lets no substances through
Cells have impermeable, permeable and selectively permeable membranes.
no
what is impermeable
An aquifer forms when groundwater pools between a permeable layer and an impermeable layer.

No! it isn't impermeable?
Glucose is permeable, meaning it can pass through cell membranes.
Unable to be penetrated. Not permeable.
