The correct Answer is:
To solve the question regarding the functions of plant growth promoters and plant growth inhibitors, we will categorize the given functions into two groups based on their roles. ### Step-by-Step Solution: 1. **Identify Plant Growth Promoters**: - Plant growth promoters are substances that enhance various growth processes in plants. The functions associated with them include: - (i) Cell division - (ii) Cell enlargement - (iii) Pattern formation - (iv) Tropic growth - (v) Flowering - (vi) Fruiting - (vii) Seed germination 2. **Identify Plant Growth Inhibitors**: - Plant growth inhibitors are substances that suppress or slow down growth processes. The functions associated with them include: - (viii) Response to wounding - (ix) Response to stresses of biotic and abiotic origin - (x) Dormancy 3. **Match Functions to Categories**: - Based on the above identification: - **Growth Promoters**: (i), (ii), (iii), (iv), (v), (vi), (vii) - **Growth Inhibitors**: (viii), (ix), (x) 4. **Select the Correct Option**: - Now we will compare this categorization with the provided options: - **Option 1**: Growth promoters - (i), (ii), (vii), (ix) (Incorrect) - **Option 2**: Growth promoters - (viii), (ix), (x) (Incorrect) - **Option 3**: Growth promoters - (i), (ii), (iii), (iv), (v), (vi), (vii) and Growth inhibitors - (viii), (ix), (x) (Correct) - **Option 4**: Growth promoters - (i), (ii), (iii), (iv), (v), (vi), (vii), (ix), (x) (Incorrect) 5. **Conclusion**: - The correct option that segregates the functions of plant growth promoters and inhibitors accurately is **Option 3**.
