Solution
The correct option is D All of the above
Collenchyma is simple living tissue with thick non-lignified walls and uneven deposition of cellulose and pectin. They are derived from parenchyma and are present in groups under epidermis to provide flexible support to the growing plant's organs and thus are present in young dicot stem, pedicel, and petioles, not in leaf base and roots, which are not the growing part. It is not present in monocots.
