Question:
Secondary metabolites like glucosinolates are produced by cabbage to
Secondary metabolites like glucosinolates are produced by cabbage to
Show Hint
Secondary metabolites = Defense
Examples: Alkaloids, tannins, glucosinolates
Updated On: May 8, 2026
- protect it from many pests
- attracts insects for pollination
- kills weeds around it
- improve soil fertilization
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept: Secondary metabolites are organic compounds that are not directly involved in growth and development but play important ecological roles.
• They help plants defend against herbivores, pathogens, and pests.
• Glucosinolates are sulfur-containing compounds found in plants like cabbage.
• On tissue damage, they produce toxic substances that deter herbivores.
Step 1: Understand function of secondary metabolites.
They are mainly involved in defense mechanisms.
Step 2: Role of glucosinolates.
They produce toxic compounds (e.g., mustard oils) that repel or harm insects and herbivores.
Step 3: Analyze options.
• (A) Protection from pests: Correct
• (B) Pollination: Involves nectar/colour, not toxins
• (C) Weed killing: Allelopathy (different compounds)
• (D) Soil fertilization: Not related
Step 4: Conclusion.
Thus, glucosinolates help in protecting the plant from pests. Final Answer: Option (A)
