Answer: Honestly I remember it by thinking of something from daily life.
Explanation:
Think of it as a concrete wall. It's ridged, hard, and you really can't get by it. Only special things can break it. Think of those special things as the nutrients for the plant.
I've always found silly ways to remember things.. it may not help you, but it's worth a try!
<span>Cell membrane - (not to be confused with the cell wall)... i visualise it as a sieve, where diffusion occurs (certain substances can move in and out of the cell). Remember in a plant cell, with a cell wall that the membrane is INSIDE the cell wall. </span>
