|
|
Intercellular space is less in collenchyma tissues
|
|
|
collenchyma cells are living cell
|
|
|
cells of collenchyma have very thin cell wall
|
|
|
collenchyma cells provide mechanical support
|
Detailed explanation-1: -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-2: -So, the correct answer is ‘Collenchyma occurs in layers below epidermis in dicotyledonous plants. ‘
Detailed explanation-3: -Collenchyma cells are elongated, living cells that occur especially in peripheral positions in leaves and stems of eudicotyledons where they provide mechanical support while they are still growing [1, 2, 3]. At maturity, the cell walls are thick and usually non-lignified, with the thickening often unevenly distributed.
Detailed explanation-4: -Parenchyma cells are often living cells and may remain meristematic, meaning that they are capable of cell division if stimulated. They have thin and flexible cellulose cell walls and are generally polyhedral when close-packed, but can be roughly spherical when isolated from their neighbors.
