Question:medium

Given below are two statements:

Statement (I): In garlic modified roots are economic part.

Statement (II): Characteristic odour in garlic is due to volatile organic sulfur-containing compounds that are rapidly produced upon tissue damage and diffuse into the air.

In light of the above statements, choose the most appropriate answer from the options given below.

Show Hint

Think about what part of the plant forms the garlic bulb.
  • Both Statement (I) and Statement (II) are correct.
  • Both Statement (I) and Statement (II) are incorrect.
  • Statement (I) is correct but Statement (II) is incorrect.
  • Statement (I) is incorrect but Statement (II) is correct.
Show Solution

The Correct Option is D

Solution and Explanation

Start by identifying what the garlic bulb actually is botanically. It develops from a shortened underground stem, the basal plate, with each clove being a modified, fleshy leaf base attached to it, so the economic part is a modified stem and leaf system, not a root, and Statement (I) fails on this point. The pungent smell is a chemical defence response, released only when cells are ruptured and the enzyme alliinase converts odourless alliin into volatile sulfur compounds such as allicin, which matches Statement (II) exactly. \[\boxed{\text{Statement (I) incorrect, Statement (II) correct}}\]
