a: plant cell ~
b: a water balloon in a cardboard box
What:
"A plant cell is like a water balloon in a cardboard box: The water in the balloon pushes outward and the box pushes inward, creating a strong building block that let plants stand tall. In the dwarf mutant, RG-II strands don't cross-link so the box - or cell wall - is more like soggy cardboard"
