Which of the following mostly pollinate brightly coloured flowers having fragrance and nectar?

Options

A. Water
B. Wind
C. Insects
D. Gecko lizard

Answer

To determine which agents mostly pollinate brightly colored flowers that have fragrance and nectar, we can analyze the options provided: Water, Wind, Insects, and Lizard.

### Step-by-Step Solution:

1. **Understanding Pollination**:
- Pollination is the transfer of pollen grains from the anther (male part) to the stigma (female part) of a flower. This process is essential for the reproduction of flowering plants.

2. **Identifying Pollination Agents**:
- Pollination can occur through various agents, including water, wind, and insects. Each of these agents has different characteristics and preferences.

3. **Analyzing Water Pollination**:
- Water pollination is rare and is limited to a few genera, primarily in monocots. Flowers that rely on water for pollination are generally not colorful and do not produce nectar.

4. **Analyzing Wind Pollination**:
- Wind-pollinated flowers are usually not brightly colored and do not produce nectar. They have light and non-sticky pollen grains to facilitate movement through air currents.

5. **Analyzing Insect Pollination**:
- Insects, particularly bees, are the dominant biotic pollinators. Insect-pollinated flowers tend to be large, brightly colored, and produce fragrance and nectar to attract these pollinators.

6. **Conclusion**:
- Based on the characteristics of the different pollination agents, the correct answer is **Insects**. They are primarily responsible for pollinating brightly colored flowers that have fragrance and nectar.

### Final Answer:
**Insects** are the agents that mostly pollinate brightly colored flowers having fragrance and nectar.
