Plants show flower in specific seasons of summer and winter.

Explanation

**Step-by-Step Solution:**

1. **Understanding Photoperiodism**: The first step is to understand the concept of photoperiodism, which refers to the physiological reaction of organisms to the length of day or night. In plants, this response is crucial for determining the timing of flowering.

2. **Classification of Plants**: Plants can be classified based on their photoperiodic response into two main categories: long day plants and short day plants.
- **Long Day Plants**: These plants require longer daylight hours to flower. They typically bloom in the summer when the days are longer.
- **Short Day Plants**: In contrast, these plants require shorter daylight hours to induce flowering. They usually bloom in the winter when the days are shorter.
