|
Cells of collenchyma have thickened corners due to the deposition of
|
|
Cellulose
|
|
|
Hemicellulose
|
|
|
Pectin
|
|
|
All of these
|
Explanation:
Detailed explanation-1: -Due to the hemicellulose, cellulose, and pectin deposits, the cells of collenchyma tissue are significantly thickened at the corners.
Detailed explanation-2: -In chollenchyma the cell walls are unevenly thickened due to deposition of excessive cellulose and pectin.
Detailed explanation-3: -Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross section. The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells.
Detailed explanation-4: -So, the correct answer is ‘pectin’.
Detailed explanation-5: -Pectin and cellulose are deposited at the corner of cells in collenchyma.
