Plasmodesmata

Plasmodesmata are microscopic channels found between the cells of plants that allow for the movement of molecules, such as proteins, lipids and RNA. These channels are essential for communication and exchange of essential materials between cells, regulating cellular activities and ultimately determining the development of the entire organism. Plasmodesmata are also important for defence mechanisms of plants, allowing for a more efficient transmission of information about stress and disease to other cells in the organism, enabling a quicker and more effective reaction to harmful factors. Additionally, Plasmodesmata are involved in the transport of hormones, for example auxins, which are involved in the regulation of plant development. Altogether, these microscopic channels play a crucial role in the plant's biology, both in growth and defence.
