A) The connections between cells in both are lined by their fused plasma membranes.
B) Both structures are composed of connexons.
C) Both bring gases and nutrients to every cell through capillaries.

Question

Quizplus · Accepted Answer

Gap junctions in animal cells and plasmodesmata in plant cells both facilitate intercellular communication by allowing the passage of small molecules and ions between adjacent cells. The size of the channels in both structures is similar, enabling comparable diffusion rates for substances between cells.
