The ovaries of different flowers may contain

Options

A. only one ovule
B. many ovules
C. one to many ovules
D. only two ovules

Explanation

### Step-by-Step Solution:

1. **Understanding the Structure of a Flower**:
- A flower consists of male and female reproductive organs. The male part is called the stamen, and the female part is called the carpel.

2. **Identifying the Components**:
- The stamen is made up of the anther (where pollen grains are produced) and the filament.
- The carpel consists of three parts: stigma, style, and ovary.

3. **Role of Pollen Grains**:
- Pollen grains contain male gametes. They are released from the anther and land on the stigma of the flower.

4. **Fertilization Process**:
- After landing on the stigma, pollen grains create a tube that grows down the style to reach the ovary, where ovules are located.
- The ovules contain female gametes.

5. **Formation of Seeds and Fruits**:
- Upon fertilization, the ovule develops into a seed, and the ovary develops into a fruit.

6. **Variation in Ovules**:
- Different flowers can have different numbers of ovules in their ovaries. Some flowers have only one ovule (like mango), while others can have many (like watermelon).
- Therefore, the ovaries of different flowers may contain from one to many ovules.

7. **Conclusion**:
- Based on the explanation, the correct answer to the question is **option C: one to many ovules**.
