AThe gap junction
BThe tight junction
CThe desmosome
DThe plasmodesma
Answer & Solution
Correct answer: D. The plasmodesma
1. Cells can communicate by direct contact through intercellular junctions.
2. Plant cells and animal cells use different ones.
3. Plasmodesmata are the junctions between plant cells.
4. Tight junctions, gap junctions and desmosomes are all animal cell contacts, so none of them is plant-only.
