The correct Answer is:
To determine how many plants among China rose, Ocimum, sunflower, mustard, Alstonia, guava, Calotropis, and Nerium have opposite phyllotaxy, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Phyllotaxy**: Phyllotaxy refers to the arrangement of leaves on the stem or branch of a plant. There are three main types of phyllotaxy: - Opposite - Alternate (or Spiral) - Whorled 2. **Identify the Plants**: We need to analyze the given plants: - China Rose - Ocimum (Basil) - Sunflower - Mustard - Alstonia - Guava - Calotropis - Nerium 3. **Classify Each Plant**: - **Opposite Phyllotaxy**: In this type, pairs of leaves arise at each node and are opposite to each other. - **Ocimum**: Opposite - **Guava**: Opposite - **Calotropis**: Opposite - **Alternate (or Spiral) Phyllotaxy**: Leaves are arranged alternately at each node. - **China Rose**: Alternate - **Sunflower**: Alternate - **Mustard**: Alternate - **Whorled Phyllotaxy**: More than two leaves arise from a single node. - **Alstonia**: Whorled - **Nerium**: Whorled 4. **Count the Plants with Opposite Phyllotaxy**: From the classification: - The plants with opposite phyllotaxy are: - Ocimum - Guava - Calotropis - This gives us a total of **3 plants** with opposite phyllotaxy. ### Final Answer: **3 plants** (Ocimum, Guava, Calotropis) have opposite phyllotaxy. ---
