| There
are three general types of tissue found in plants. These are Epidermal, Ground & Vascular. The Epidermis covers the outside of the entire plant body and is like the wooden mold used to make reinforced concrete. Vascular Tissues are like the steel rods in reinforced Concrete. |
|
||
| Ground Tissues are like the
cement in reinforced concrete. Ground Tissues perform most of the physiological process in plants. They also contribute to the structural support of plants. |

Parenchyma Cells can have an Isodiametric shape like a Sphere. They have Thin Primary Walls, a Large Central Vacuole & Well Developed Plastids. | ||
|
Parenchyma cells can begin differentiating close to meristematic cells. Parenchyma cells are not mitotic but can divide following injury . | ||
 |
Parenchyma cell walls generally contain large quantities of Pectins & stain Pink with Toluidine Blue. This image is from the outer part of a stem stained with Toluidine Blue. Locate the Parenchyma. | ||
 |
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. | ||
