Australian Acacia, Turmeric, Zaminkand, Nerium, Cacti, Pea, Pistia, Chrysanthemum, Nepenthis, Pine apple and garlic, out of these how many of them exhibit leaf modifications

Options

A. 6
B. 11
C. 5
D. 7

Answer

To determine how many of the listed plants exhibit leaf modifications, we will analyze each plant one by one:

1. **Australian Acacia**: In Australian Acacia, the petiole is modified into a flat leaf-like structure called a phyllode. The actual leaves may be reduced or absent, and the phyllode performs photosynthesis. **(Leaf modification present)**

2. **Turmeric**: In turmeric, there are no significant modifications of the leaves. The plant primarily uses its rhizome for storage and propagation. **(No leaf modification)**

3. **Zaminkand (Germincant)**: Zaminkand is a tropical fruit, and while it has a modified stem, there are no notable modifications of the leaves. **(No leaf modification)**

4. **Nerium**: In Nerium, there are no modifications of the leaves. The leaves are typical and serve their usual functions. **(No leaf modification)**

5. **Cacti**: In cacti, the leaves are modified into spines. This adaptation helps reduce water loss and provides protection. **(Leaf modification present)**

6. **Pea**: In pea plants, the upper leaflets are modified into tendrils, which help the plant climb. **(Leaf modification present)**

7. **Pistia**: In Pistia, there are modifications of the stem rather than the leaves. **(No leaf modification)**

8. **Chrysanthemum**: In Chrysanthemum, there are no modifications of the leaves; they are typical leaves. **(No leaf modification)**

9. **Nepenthes**: In Nepenthes, the leaves are modified into pitcher-like structures, which are used for trapping insects. **(Leaf modification present)**

10. **Pineapple**: In pineapple, the leaves are normal and do not exhibit any modifications. **(No leaf modification)**

11. **Garlic**: In garlic, the plant has modified stems (bulbs) surrounded by modified leaves. The leaves themselves do not exhibit significant modifications. **(No leaf modification)**

Now, let's summarize the findings:

- Plants with leaf modifications: **Australian Acacia, Cacti, Pea, Nepenthes** (4 plants)
- Plants without leaf modifications: **Turmeric, Zaminkand, Nerium, Pistia, Chrysanthemum, Pineapple, Garlic** (7 plants)

**Total count of plants exhibiting leaf modifications: 4**

### Final Answer: 4 plants exhibit leaf modifications.
