The correct Answer is:
To solve the question regarding the two different plants associated with the discovery of two different phytohormones that have a common biosynthetic precursor, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Phytohormones**: - The two phytohormones we are focusing on are Auxin and Abscisic Acid (ABA). 2. **Determine the Plants Associated with Each Phytohormone**: - Auxin was discovered from grass, which is characterized by versatile anthers. - Abscisic Acid (ABA) was discovered from coconut, which belongs to the Malvaceae family and is characterized by a pentalocular ovary. 3. **Identify the Common Biosynthetic Precursor**: - Both Auxin and Abscisic Acid share a common biosynthetic precursor known as Monolonic Acid. 4. **Analyze the Given Options**: - I. Versatile anthers (associated with Auxin) - II. Compound spadix (not specifically linked to either hormone) - III. Pentalocular ovary (associated with Abscisic Acid) - IV. Trifoliate compound leaves (not specifically linked to either hormone) 5. **Select the Correct Characters**: - From the analysis, we can conclude that: - Auxin is linked to versatile anthers. - Abscisic Acid is linked to pentalocular ovary. - Therefore, the correct answer includes versatile anthers and pentalocular ovary. 6. **Final Answer**: - The two characters exhibited by the plants associated with the discovery of the two phytohormones are: - I. Versatile anthers (for Auxin) - III. Pentalocular ovary (for Abscisic Acid) ### Conclusion: The correct options that exhibit the characters of the two different plants associated with the discovery of two different phytohormones are: - **I. Versatile anthers** - **III. Pentalocular ovary** ---
