Question:

Which one of the following is a xerophytic plant in which the stem is modified into a flat green and succulent structure:

Options:

1. Casuarina
2. Hydrilla
3. Acacia
4. Opuntia

Solution:

Opuntia is a xerophytic plant in which the stem is modified into a flat, green, and succulent structure. The modified stem of Opuntia, also known as a cladode or a pad, serves as a water storage organ, allowing the plant to survive in arid and dry environments with limited water availability. Opuntia is commonly known as a prickly pear cactus and is well-adapted to grow in dry and desert regions. Casuarina, Hydrilla, and Acacia are not known for having flat green and succulent stems like Opuntia.
