Science — AI-generated practice question

Plants store their waste products using several methods:

• Waste products like resins and gums are stored in old xylem.
• Wastes are stored in cellular vacuoles.
• Some waste products are stored in leaves that fall off.
• Plants also excrete some waste substances into the surrounding soil.

The examiner expects students to name specific storage methods — vacuoles, resins/gums in old xylem, falling leaves, and excretion into soil. Simply writing "plants store waste in vacuoles" alone will fetch only 1 mark. For 2 marks, give at least two distinct methods. Avoid writing about oxygen/CO₂/transpiration here, as those deal with gaseous wastes, not stored wastes. The key section is 5.5.2.
