प्रश्न

Describe various stem modifications associated with food storage, climbing and protection.

दीर्घउत्तर

उत्तर

  1. Food storage – Underground stems of potato, ginger, turmeric, Samarkand and Colocasia are modified to store food in them.
  2. Climbing – Stem tendrils which develop from axillary buds, are slender and spirally coiled and help plants to climb such as gourds (cucumber, pumpkins, watermelon) and grapevines.
  3. Protection – Axillary buds of stems may also get modified into woody, straight and pointed thorns. Thorns are found in many plants such as Citrus and Bougainvillea.
