Answer

To analyze the given assertion and reason, we can break it down step by step:

### Step 1: Understand the Assertion
The assertion states that "Young leaves in Poinsettia are brightly coloured to attract pollinators and achieve pollination."

- **Explanation**: Poinsettia plants have modified leaves known as bracts that are brightly colored. These bright colors serve to attract pollinators, such as insects, which are essential for the pollination of the true flowers of the plant.

### Step 2: Evaluate the Reason
The reason states that "It is only color which can attract the pollinator on all plants."

- **Explanation**: This statement is misleading. While color can attract pollinators, it is not the only factor. Other elements such as scent, nectar availability, and flower shape also play significant roles in attracting pollinators. Therefore, this statement is incorrect.

### Step 3: Determine the Truth of Both Statements
- The assertion is **true** because the bright colors of the young leaves (bracts) in Poinsettia do attract pollinators.
- The reason is **false** because it incorrectly claims that color is the only factor that attracts pollinators across all plants.

### Conclusion
Based on the evaluation:
- The assertion is true.
- The reason is false.

Thus, the correct answer is that the assertion is true, but the reason is false.
