A tissue of vegetable cells which are thickend at the angles and (usually) elongated.
a ground tissue in plants which has slightly uneven cell walls and has a supportive function, but cell elongation is possible.
n. (L. from Gr. killa, glue, and enchyma, an infusion) living, supportive tissue with chloroplasts generally just beneath the surface consisting or more or less elongated cells usually thickened unevenly in a manner somewhat variable in different groups of plants.
Collenchyma are living cells that are used for strengthening. They are elongate with thick walls in the corners where several of these cells come together. These cells are typically found just under the epidermis in a number of different types of stems. The stringy cells in celery are collenchyma cells. DIAGRAMS: Tissue Types PHOTOS
A tissue composed of relatively elongated cells with secondarily thickened walls of cellulose. A supporting or strengthening tissue.
Usually juvenile supportive tissue, consisting of living cells with thickened walls.
kol-LEN-kah-mah Elongated, living cells that differentiate from parenchyma and support growing regions of shoots. 536
tissue composed of unevenly thickened cell walls; collenchyma cells are flexible and support young parts of the plant without hindering growth; collenchyma cells are composed of cellulose
A supporting plant tissue similar to parenchyma cells, but have cellulose wall thickenings.
One of the three major cell types in plants; are elongated and have thicker walls than parenchyma cells and are usually arranged in strands; provide support and are generally in a region that is growing. PICTURE 1 PICTURE 2
cells that are living at maturity and have irregularly thickened walls. provide mechanical support
