What would happen to a cell of materials could not move across the cell membrane?

"Isolation". And most materials can NOT move across the cell membrane. (For many things your cells have special proteins within the membrane for transport.)

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
