The plants with flowers having strong odour, abundant nectar and pollen grain show

Options

A. (a) ornithophily
B. (b) chiropterophily
C. (c) entomophily
D. (d) anemophily

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the characteristics of flowers that have a strong odor, abundant nectar, and pollen grains.

2. **Identifying Pollination Types:**
We need to analyze the different types of pollination mentioned in the options:
- **Ornithophily:** Pollination by birds. Flowers are typically large, brightly colored, odorless, and have dilute nectar.
- **Chiropterophily:** Pollination by bats. These flowers often open at night, have a strong odor, are usually colorless or white, and contain abundant nectar and pollen grains.
- **Entomophily:** Pollination by insects. These flowers have a pleasant fragrance, are large, and contain abundant nectar and pollen grains.
- **Anemophily:** Pollination by wind. These flowers are generally colorless, odorless, nectarless, and small in size.

3. **Analyzing the Characteristics:**
- The key characteristics we are looking for are:
- Strong odor
- Abundant nectar
- Presence of pollen grains

4. **Matching Characteristics with Pollination Types:**
- **Ornithophily:** Does not match due to odor and nectar characteristics.
- **Chiropterophily:** Matches well as it has strong odor, abundant nectar, and pollen grains.
- **Entomophily:** Also matches well with abundant nectar and pollen grains, but the strong odor is not as prominent as in chiropterophily.
- **Anemophily:** Does not match due to lack of odor and nectar.

5. **Conclusion:**
Based on the analysis, the best-suited answer is **Chiropterophily (pollination by bats)**, as it specifically mentions strong odor, abundant nectar, and pollen grains.

**Final Answer:**
The plants with flowers having strong odor, abundant nectar, and pollen grains show **Chiropterophily (pollination by bats)**.
