👉 Plasmodesmata is a term used in biology to describe structures that form within cells. These structures are specialized organelles, which can be found in various cellular processes and functions. Plasmodesms are characterized by their ability to form into small vesicles or tubes, allowing them to move through the cell membrane for purposes of transport or secretion. They play a role in regulating the movement of substances between different parts of the cell, such as hormones and neurotransmitters.
