State whether the following is true or false.
Plasmodesmata in plants are functionally comparable to gap junctions in animals.

  • A.False only at small scales
  • B.True
  • C.False
  • D.True only at large scales

Both create direct cytoplasmic continuity between neighbouring cells, allowing small molecules to pass without crossing a membrane. Their structures differ entirely, since plasmodesmata must traverse a cell wall as well.
