Answer 1

Answer: (A)

Old xylem

Resins and gums are metabolic by-products of plant tissues. They are formed in the specialized structures called passages ducts. Gums are the waste products usually formed due to the disintegration of the plant cellulose.

These byproducts are stored in the vacuoles of the ageing cell such as old xylem. These cells die and then fall off eventually.
