A "typical" Parenchyma Cell is Isodiametric, has thin walls, a large central Vacuole & well developed Plastids. | ||
|
Parenchyma cells can begin differentiating close to meristematic cells. This image is from the root apical meristem of the world-famous cycad Zamia pumila. Parenchyma cells are not mitotic but can become so following injury or the reception of developmental stimuli from plant growth regulators or trauma. Think about that the next time you bite a vegetable!!!!!! | ||
|
Parenchyma cell walls generally contain large quantities of Pectins & stain pink with Toluidine Blue. Find the Parenchyma in this cross-section of Hoya (Wax Plant) stem!!!! |

Parenchyma Tissues are usually massive and contain many adjacent Parenchyma cells. This image is from a stem, stained with Toluidine Blue. | ||
|
Commercial slides are typically stained with Fast Green and Safranin. Parenchyma cells may appear green with these stains. The green material between cells is probably a carbohydrate secreted by the adjacent parenchyma cells. Find the crystals in this image. | ||
