| ground tissue The tissue of a plant other than the epidermis, periderm, and vascular tissues, consisting primarily of parenchyma, and (in lesser amounts) of collenchyma and sclerenchyma. Cortex and pith are subtypes of ground tissue. |
All of this second region lying between the epidermis and the fibro-vascular bundle is known as the ground tissue.
It is sharply separated from the ground tissue by a row of small cells, called the “bundle sheath.”
The ground tissue of the leaf is composed of very loose, thin-walled cells, containing numerous chloroplasts.
There is a bundle sheath of much-flattened cells separating the fibro-vascular bundle from the ground tissue.
The bulk of the ground tissue is made up of rather large, loose cells, the outer ones containing a good deal of chlorophyll.
The outer cells of the ground tissue in the green branches contain chlorophyll, and the walls of some of them are thickened.
The ground tissue is composed of large, loose cells, which in the older roots are often ruptured and partly dried up.
The ground tissue is composed of comparatively large cells with thickish, soft walls, that contain much starch.
A third series is disposed around a fairly large amount of ground tissue, which may or may not have a cavity in the centre.
The cells of the ground tissue lying just inside the vascular bundles are all very much thickened.
