Question

Quizplus · Accepted Answer

Plasmodesmata allow movement of materials in both directions, not only one direction. They are channels that connect the cytoplasm of adjacent plant cells and allow the exchange of various molecules and substances, including small metabolites, ions, and sometimes even viruses. The desmotubule, which is found at the center of some plasmodesmata, is derived from the endoplasmic reticulum and helps to maintain the structure and function of the channel. However, plasmodesmata are not lined by the fused membranes of adjoining cells, as stated in choice A.
