    Mohit was asked to draw a labelled diagram of sclerenchyma tissue as seen in longitudinal section. The figure he drew is shown here. Point out the mistake in the figure.

    A) Instead of simple pit pore, it should be bordered pit.

    B) The cell walls are not lignified in sclerenchyma.

    C) The nucleus and cytoplasm are not shown.

    D) The figure shows transverse section instead of longitudinal section of tissue.

    Correct Answer: D

    Solution :

    The figure shows transverse section of sclerenchyma tissue. It is a simple supportive tissue of highly thick-walled cells with little or no cytoplasm. The thickening of cell walls may be due to deposition of lignin or both lignin and cellulose. The adjacent cells possess simple oblique pits.
