taimedele iseloomulik kõrvutiasetsevaid rakke ühendav rakukesta läbiv rakumembraaniga vooderdatud reguleeritava läbimõõduga kanal, mis sisaldab tsütoplasmat ja desmotuubuliks nimetatavat endoplasma retiikulumi, Microscopic channels which traverse the cell walls of adjacent plant cells, enabling transport and communication between them., kanalid, mis läbivad kahe kõrvutiasetseva taimeraku seinu on sarnased loomaraku aukliidustele, Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them. Plasmodesmata evolved independently in several lineages, and species that have these structures include members of the Charophyceae, Charales, Coleochaetales and Phaeophyceae (which are all algae), as well as all embryophytes, better known as land plants.
