All bee pollinated flowers possess

Options

A. Bluish colour
B. Purplish colour
C. Landing platform
D. Long corolla.

Answer

### Step-by-Step Solution:

1. **Understanding Pollination**: Pollination is the process of transferring pollen grains from the anther (male part) to the stigma (female part) of a flower. This can occur within the same flower (self-pollination) or between different flowers (cross-pollination).

2. **Identifying Bee Pollination**: The question specifically asks about flowers that are pollinated by bees. Bees are attracted to certain characteristics in flowers that facilitate their pollination activities.

3. **Analyzing Flower Characteristics**:
- **Color**: While bees are attracted to certain colors, they prefer yellow and white flowers rather than blueish or purplish colors. Therefore, color alone is not a defining characteristic for all bee-pollinated flowers.
- **Landing Platform**: Bees, being larger insects, require a stable surface to land on while they collect nectar. This is crucial for their feeding and pollination activities.

4. **Conclusion**: The essential characteristic that all bee-pollinated flowers possess is a **landing platform**. This feature allows bees to rest and feed, facilitating the process of pollination effectively.

5. **Final Answer**: The correct option is that all bee-pollinated flowers possess a **landing platform**.
