Correct Answer

(1) Plasmodesmata,Plant cells
(2) Tight junctions,Animal cells
(3) Desmosomes,Animal cells
(4) Gap junctions,Animal cells

Explanation

Cell junctions differ between plant and animal cells:

  • Plasmodesmata - cytoplasmic channels unique to plant cells; pass through cell walls to connect adjacent cells
  • Tight junctions - seal adjacent animal cells together preventing leakage
  • Desmosomes - mechanical anchors between adjacent animal cells
  • Gap junctions - channels between adjacent animal cells allowing direct ion and molecule exchange
