The correct Answer is:
To solve the question regarding the matches of plant hormones and their functions, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Cytokinins - Inhibits secondary cambial growth**: - Cytokinins are known for promoting cell division and growth in plants. They can inhibit secondary growth by affecting the activity of the cambium, which is responsible for secondary growth. Thus, this statement is **correct**. 2. **Ethylene - Prevents senescence**: - Ethylene is a plant hormone that actually promotes senescence (aging) in plants, particularly in leaves and fruits. Therefore, this statement is **incorrect**. 3. **Abscisic acid - Stops cambial activity**: - Abscisic acid (ABA) is known as the stress hormone and plays a role in inhibiting growth and promoting dormancy. It does stop cambial activity, particularly under stress conditions. Thus, this statement is **correct**. 4. **Ethylene - Induces seed & bud dormancy**: - Ethylene is primarily known for promoting growth and breaking dormancy in seeds and buds, rather than inducing it. Therefore, this statement is **incorrect**. ### Summary of Correct Matches: - The correct statements are: - (i) Cytokinins - Inhibits secondary cambial growth (Correct) - (iii) Abscisic acid - Stops cambial activity (Correct) Thus, the correct matches are (i) and (iii). ### Final Answer: The correct statements are (i) and (iii). ---
