What are platodesmata?

Platodesmata are specialized structures found in certain types of plant cells, particularly in the phloem tissue. They are a form of plasmodesmata, which are microscopic channels that allow for the transport of substances between plant cells. Platodesmata specifically facilitate the movement of nutrients and signaling molecules, playing a crucial role in cell communication and the overall functioning of the plant. Their presence contributes to the efficient transport of photosynthetic products throughout the plant.
