You. compare and contrast communication by nerve signal with communication across plasmodesmata.

A nerve signal is a type intracellular communication involving an electrical charge moving along the cell membrane like a wave.

Direct connections between the cells in plants are called plasmodesmata. They function similarly to the gap junctions in animal cells. Plasmodesmata allow molecules to pass directly from the cytoplasm of one cell to the cytoplasm of an adjacent cell.
