Question

Which of the following structures may be traversed by plasmodesmata that connects the cytoplasm of two neighbouring plant cells?


A
Middle lamella only
loader
B
Endoplasmic reticulum only
loader
C
Both cell wall and middle lamella

D
Plasma membrane only

Solution

The correct option is C Both cell wall and middle lamella
Plasmodesmata are small channels that directly connect the cytoplasm of neighbouring 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 option is 'Both call wall and middle lamella'.
