Which is not correct about entomophilous flowers

Options

A. Pollen grains are heavy and sticky
B. Stigmas are unbranched
C. Sepals are not well developed.
D. Petals brightly coloured

Answer

To determine which statement is not correct about entomophilous flowers, we will analyze each statement one by one:

1. **Pollen grains are heavy and sticky.**
- **Analysis:** This statement is correct. Entomophilous flowers produce pollen grains that are heavy and sticky to ensure they adhere to the bodies of insects that visit the flowers for nectar. This helps in effective pollination as the insects carry the pollen to other flowers.

2. **Stigmas are unbranched.**
- **Analysis:** This statement is also correct. In entomophilous flowers, the stigmas are typically unbranched. This is in contrast to anemophilous flowers (wind-pollinated flowers), which often have branched stigmas to capture airborne pollen.

3. **Sepals are not well developed.**
- **Analysis:** This statement is incorrect. In entomophilous flowers, both sepals and petals are usually well developed. The sepals help protect the flower bud and can also play a role in attracting pollinators, similar to petals.

4. **Petals are brightly colored.**
- **Analysis:** This statement is correct. Entomophilous flowers often have brightly colored petals to attract insects. Additionally, many of these flowers emit fragrances to further entice pollinators.

**Conclusion:** The statement that is not correct about entomophilous flowers is that "sepals are not well developed." Therefore, the answer is option number three.
