Answer

To solve the question "_________ functions as landing platform for the pollen grains in flowering plants," we need to identify the part of the flower that serves this specific function.

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the part of a flowering plant that acts as a landing platform for pollen grains.

2. **Identify Flower Parts**: In flowering plants, the female reproductive structure consists of several parts, including the stigma, style, ovary, and ovules.

3. **Define Each Part**:
- **Stigma**: The top part of the pistil that receives pollen.
- **Style**: The stalk that connects the stigma to the ovary.
- **Ovary**: The enlarged basal portion of the pistil that contains ovules.
- **Ovules**: The structures within the ovary that develop into seeds after fertilization.

4. **Determine the Function of Each Part**:
- The stigma is specifically designed to catch and hold pollen grains when they land on it.
- The style and ovary do not serve as landing platforms; they are involved in the process after the pollen has landed.

5. **Conclusion**: Based on the definitions and functions, the stigma is the part of the flower that functions as the landing platform for pollen grains.

### Final Answer:
The correct answer is **stigma**.
