WebJun 7, 2024 · Plasmodesmata (singular plasmodesma) mediate direct cell-to-cell communication between neighboring cells; this facilitates the transport of cellular contents that vary in size and chemical form. They are one of the key cellular structures that distinguish plants from the animal system. WebDec 17, 2024 · Plasmodesmata connect neighbouring cells throughout a plant to establish the symplast. Plasmodesmata establish an interconnected cytoplasm called the symplast, through which metabolites, proteins, and RNAs are exchanged between cells, tissues, and organs.
