Cells are thickened at the corners
WebThe elongated cells look like fibre with both ends tapered and may attain a length of 2 mm though rarely. iv. Arrangement: Collenchyma tissue appears to be more or less compactly arranged as the thickening materials deposit more heavily at the corners and on the radial walls of cell in addition to normal uniform thickening. WebSep 6, 2024 · These cell walls are thick due to the deposition of cellulose and pectin on the cell walls. This thickness is not evenly distributed as the cell wall is thick mostly at the corners but not at the center. All these cells are arranged very closely so intercellular spaces are not present in this tissue.
