Answer 2

ANSWER:

Substances like resin, gum etc. are given out of the plants as these are wastes for the plants.

EXPLANATION:

These are secreted out of the plant body so that these wastes do not prove to be harmful for the plants.

These wastes are stored in the secretory tissues of the plants from which they are then excreted out of the plant. These materials are toxic for the plants and so the plants secret these out when they are formed in the plant body.
