Two slides of plant tissues parenchyma and sclerenchyma
Deepa was shown two slides of
plant tissues: parenchyma and sclerenchyma.
She can identify sclerenchyma by the
(a) location of nucleus
(b) size of cells
(c) thickness of cell walls
(d) position of vacuoles
Answer: (c) thickness of cell walls.
The walls of sclerenchyma tissues are thickened due to lignin (a chemical substance which acts as cement and hardens them).
