hey dear...!!
Collenchymatous cells are longer
than parenchyma cell.. They are living. The intercellular spaces in this tissue are absent because in intercellular spaces at the corner of cells thickenings of cellulose and pectin develop due to which the cell wall become rigid and thick at corners. Sometimes collenchyma develops chloroplasts. Collenchyma is usually found as 3-4 layered hypodermis of herbaceous dicotyledonous stem. They are absent in monocot stems.
Functions :
1. It provides mechanical support to the organs and due to its peripheral position in stems it resists bending and pulling action of wind.
2. When chloroplasts are present it takes part in photosynthesis.
