Model Answer
Plants use the following strategies to excrete waste products:
- Storage in vacuoles and leaves: Waste products are stored in cellular vacuoles or in leaves. When leaves fall off, these wastes are removed from the plant body.
- Storage as resins and gums: Waste products are stored as resins and gums, especially in old xylem. Plants also excrete some waste substances into the surrounding soil.

Explanation
- The question asks for any two strategies — pick two distinct ones and name them clearly.
- Examiners expect the key terms: vacuoles, falling leaves, resins and gums/old xylem, and soil excretion — use at least two of these.
- Transpiration (removing excess water) is also valid as a third point, but stick to two as asked.
- Avoid vague answers like "plants store waste" without stating where or how.
