|
Meristems |
Undifferentiated tissue and which active cell division takes place. Found in the root tips, buds, cambium, Cork cambium, and Latent buds |
|
|
Differentiation |
Process in the development of cells in which they become specialized for various functions |
|
|
Primary growth |
Root and stem growth in length. Occurs at the apical meristems and lateral meristems of all vascular plants |
|
|
Secondary growth |
Increase in root and stem growth or diameter. Occurs at lateral meristems and some vascular plants such as dicots |
|
|
Apical meristems |
Growing point at tips of shoots and roots |
|
|
Buds |
(1) small lateral or terminal protuberance on the stem of a plant that may develop into a flower or shoot. (2) undeveloped flower or shoot containing a meristematic growing point |
|
|
Cambium |
Thin layer of meristematic cells that give rise to the phloem and to xylem increasing stem and root diameter |
|
|
Xylem |
Main water and mineral conducting tissue and trees and other plants. Provides structural support. Arises from the cambium and becomes would after lignifying contrast with phloem |
|
|
Phloem |
Plant vascular tissue that transports photosynthates and growth regulators. Situated on the inside of the bark just outside the cambium. Is bi-directional. Contrast with xylem. |
|
|
Cork cambium |
Meristematic tissue from which the Corky, protective outer layer of bark is formed |
|
|
Periderm |
The outer layers of tissue of Woody roots and Stems, consisting of the Cork cambium and the tissues produced by it, such as bark |
|
|
Cellulose |
Complex carbohydrate found in the cellular walls of the majority of plants and algae and certain fungi |
|
|
Lignin |
Organic substance that impregnates certain cell walls to thicken and strengthen the cell to reduce susceptibility to Decay & Pest damage |
|
|
Carbohydrate |
Compound, combining carbon, hydrogen, and oxygen that is produced by plants as a result of photosynthesis. Sugars and starches |
