Quick Summary

Prosenchyma is a type of plant tissue composed of elongated, typically pointed cells that have little to no protoplasm. These tissues are primarily involved in conduction and support within plants.1

Prosenchyma cells are a component of the ground tissue system in plants, which also includes parenchyma, collenchyma, and sclerenchyma. While parenchyma cells are generally undifferentiated and retain their protoplasts for metabolic activities, prosenchyma cells are specialized for transport and structural roles. They are distinct from parenchyma, which are typically thin-walled and adaptable to various functions like photosynthesis and storage.23

Prosenchyma cells are starch-containing parenchymal cells whose cell walls have become lined with lignin, as occurs in the stems of Bougainvillea (Nyctaginaceae). A specialized type of parenchyma cell, called a transfer cell, is involved in the short-distance movement of solutes by cell-to-cell transfer. Transfer cells
