Choose the mis-matched pair

Options

A. Whorled phyllotaxy - Alstonia
B. Phyllode - Australian Acacia
C. Opposite phyllotaxy - Calotropis
D. Leaf tendril - Cucurbits

Answer

To solve the question of identifying the mismatched pair, we will follow these steps:

### Step 1: Understand the concept of phyllotaxy
Phyllotaxy refers to the arrangement of leaves on a stem. It is important to know different types of phyllotaxy and examples associated with them.

### Step 2: Identify the examples given
From the transcript, we can gather that several examples of phyllotaxy are mentioned:
- Sunflower (likely an example of alternate phyllotaxy)
- Calotropis (also mentioned in relation to phyllotaxy)
- Achesia (related to flattened ratchets and photosynthesis)
- Tendrils in plants (specifically mentioning the difference between stem tendrils and leaf tendrils)

### Step 3: Analyze the examples for correctness
We need to check if the pairs mentioned are correctly matched:
1. Sunflower - correct example of alternate phyllotaxy.
2. Calotropis - also a valid example of a type of phyllotaxy.
3. Achesia - mentioned in the context of phyllotaxy and photosynthesis.
4. Tendrils in the context of cooker beets and pea plants - here, it is stated that tendrils in cooker beets are stem tendrils while in pea plants they are leaf tendrils. This indicates a mismatch.

### Step 4: Identify the mismatched pair
Based on the analysis, the mismatched pair is the one that incorrectly associates the type of tendril with the plant. The statement about tendrils in cooker beets being stem tendrils and in pea plants being leaf tendrils confirms that this is indeed the mismatched pair.

### Conclusion
The mismatched pair is the one related to the tendrils of cooker beets and pea plants.

### Final Answer
The mismatched pair is: Tendrils in cooker beets (stem tendrils) and tendrils in pea plants (leaf tendrils).
