The correct answer is: B.Cell junction in plant cells.
Plasmodesmata are specialized channels that connect adjacent plant cells. These channels allow for the direct exchange of water, ions, and signaling molecules (like hormones) between plant cells. They are similar to gap junctions in animal cells but are specific to plants.
Here's what the other options refer to:
A.Cell junction in animal cells: This refers to structures like gap junctions, tight junctions, and desmosomes, which help connect and communicate between animal cells. However, plasmodesmata are not found in animal cells.
