Question

Quizplus · Accepted Answer

Plasmodesmata are channels that connect the cytoplasm of adjacent plant cells. They allow for the transport of small molecules and ions between cells, but are too small for large proteins to pass through. However, some viruses have evolved movement proteins that can facilitate their transport through plasmodesmata.
