Question

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

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

Answer 1

The correct option is D Plasmodesmata

• The middle lamella is a layer rich in pectins which cement the cell walls of adjacent plant cells and forms plasmodesmata connections.
  
• Plasmodesmata are cytoplasmic channels that pass through the cell walls of the plant and few algal cells which help in the transport of substances and communication between the adjacent cells.
  
• So, the correct answer is 'Plasmodesmata'.
