Choose the correct answer:

Which type of plant products are resins and gum?

Resins and gums are metabolic byproducts that are excreted by plant cells and produced in specialized structures called passage ducts. They are both waste products that are not directly involved in the primary metabolic processes of the plant.

Gums are formed as a result of the breakdown of plant cellulose and are stored in the vacuoles of old cells, such as the xylem. These cells eventually die and the gums are released.

Resins, on the other hand, are produced by specialized cells called resin ducts and are used by plants for defense against predators and pathogens, as well as for wound healing.
