Explain the modification of leaves for food storage.

(N/A) In some plants,leaves are modified to store food. These leaves become fleshy and succulent to store nutrients and water.
Example: Onion (Allium cepa) and Garlic (Allium sativum).
Other modifications of leaves include:
$1$. Tendrils: For climbing,e.g.,Peas.
$2$. Spines: For defense,e.g.,Cacti.
$3$. Phyllode: In Australian Acacia,the leaves are small and short-lived. The petiole expands,becomes green,and synthesizes food.
$4$. Insectivorous: Leaves are modified to trap insects,e.g.,Pitcher plant and Venus flytrap.
