Question

Which one of the following structures between two adjacent cells is an effective transport pathway?

• A. Plasmalemma
• B. Plasmodesmata
• C. Plastoquinones
• D. Endoplasmic reticulum

Answer 1

The correct option is B Plasmodesmata

Plasmodesmata (singular, plasmodesma) are small channels that directly connect the cytoplasm of neighboring plant cells to each other, establishing living bridges between cells. Similar to the gap junctions found in animal cells, the plasmodesmata, which penetrate both the primary and secondary cell walls, allow certain molecules to pass directly from one cell to another and are important in cellular communication.

So, the correct answer is 'Plasmodesmata'
