Question

Quizplus · Accepted Answer

Plasmodesmata are channels that connect adjacent plant cells and allow for the exchange of substances such as water, ions, and even large molecules. Therefore, the dye is likely traveling between cells through plasmodesmata. Osmosis is the diffusion of water molecules across a semi-permeable membrane and is not relevant in this scenario. Nuclear pores are found in the nuclear envelope of eukaryotic cells and regulate the exchange of molecules between the nucleus and the cytoplasm. Integrin and dynein are both proteins involved in various cellular processes but are not directly responsible for the movement of substances between plant cells.
