Science — CBSE Class 10 board question

Leaves help in excretion in two ways:

1. Storing waste in vacuoles: Waste materials are stored in the cell vacuoles of leaves.
2. Removal through falling leaves: Waste products accumulated in leaves are removed when the plant sheds its leaves (leaf fall).

The textbook specifically states that plants get rid of waste by storing it in cell-vacuoles or removing it in falling leaves. Examiners expect both points to be clearly linked to leaves (not gums/resins or soil excretion, which relate to other plant parts). Each point is worth 1 mark — name the method and briefly explain it.
