Answer

Modifications of leaves are as follows:

  1. Leaf tendril — In case of certain weak-stemmed plants, leaves or leaflets are modified into wiry, coiled structures called tendrils. They coil around the object they touch and support the plant to climb up. E.g., Sweet Pea.
  2. Leaf spines — In some plants, leaves are modified into pointed structures called spines. Spines help to reduce water loss by transpiration. E.g., Cactus.
  3. Scale leaves — In some plants like Onion and Ginger, thick and fleshy or thin and dry scale leaves are present, respectively. Their function is to store food and protect the buds.
