Which of the following is not an aerial part of the plant?

The correct answer is "root", as it is not an aerial part of the plant. Unlike leaves, flowers, fruits, and buds, the root remains underground and does not interact directly with the air.

Key Points:

1. Aerial parts of the plant include structures like:
   • Leaves (for photosynthesis).
   • Flowers (for reproduction).
   • Fruits (for seed dispersal).
   • Buds (develop into flowers or new shoots).
2. The root is not an aerial part of the plant because:
   • It grows beneath the soil.
   • It primarily functions to absorb nutrients and water.
   • It anchors the plant firmly in the ground.
