difference between cortex and epidermis

It is the result of the activity of a secondary meristem called cork cambium, which appears between hypodermis and primary cortex. Some of the parenchyma cells in the peripheral layers of cortex undergo dedifferentiation and become meristematic. These cells now represent the cor..

. It has four cellular elements tracheids, tracheae, fibres and parenchyma of which only xylem parenchyma is living. Xylem tracheae (or vessels) are the most active water conducting elements. Based on the pattern of lignification, they can be distinguished into annular, spiral, scalariform, reticul..

Mineral nutrients absorbed from the root has to be carried to the xylem. This transport follows two pathways namely apoplastic pathway and symplastic pathway. In apoplastic pathway, mineral nutrients along with water moves from cell to cell through spaces between cell wall by diffusion. The ions, w..

1. Mildew Pathogen seen as a growth on the surface of the host. 2. Rust Small pustules of spores, usually breaking through the hoot epidermis. 3. Smuts Pustules larger than those of the rusts. 4. Scab Roughed appearance of the diseased organ. 5. Colour change Change of colour from the no..
