Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Cork cambium is a tissue found in many vascular plants as part of the epidermis. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots. A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin. Cortex is unspecialized cells lying between the epidermis (surface cells) and the vascular, or conducting, tissues of stems and roots. Cortex and cork are parenchymatous in nature.So the correct option is 'both assertion and reason are correct and the reason is the correct explanation for assertion.
