In the pea plant, leaves are modified into:

Correct option is A

The correct answer is (A) tendrils

Explanation:
• In pea plants (Pisum sativum), the terminal leaflets are modified into thread-like, sensitive structures called tendrils.
• These tendrils coil around support structures, helping the weak stem to climb.

Information Booster:
• Leaf modifications occur in plants to perform specialized functions other than photosynthesis, such as support, defense, or food storage.
• Stem tendrils (as opposed to leaf tendrils) are seen in plants like grapes and gourds.

Additional Knowledge:
• Spines (Option B): Leaves modified for defense and reducing water loss (e.g., in cacti).
• Cladodes (Option C): Stem modifications that become flat and green to perform photosynthesis (e.g., Asparagus).
• Thorns (Option D): Modified axillary buds of the stem used for protection (e.g., Bougainvillea, Citrus).
