The site of preception of light on plants for flowering is

Options

A. Stems
B. Root
C. Leaves
D. Fruits

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the specific part of the plant that perceives light for the purpose of flowering.

2. **Defining Key Terms**: The term "photoperiod" is crucial here. It refers to the duration of light exposure that a plant receives, which influences its flowering process.

3. **Identifying Plant Parts**: The options provided are stems, roots, leaves, and trunks. We need to determine which part is primarily responsible for light perception.

4. **Analyzing Each Option**:
- **Stems**: While stems support the plant and can have some light perception, they are not the primary site for flowering response.
- **Roots**: Roots are primarily involved in nutrient and water uptake and do not play a role in light perception for flowering.
- **Leaves**: Leaves are the main site for photosynthesis and are equipped with photoreceptors that detect light, making them essential for perceiving the photoperiod.
- **Trunks**: Similar to stems, trunks do not significantly contribute to the perception of light for flowering.

5. **Conclusion**: Based on the analysis, the leaves are the part of the plant that perceives light for flowering. Therefore, the correct answer is **leaves**.

**Final Answer**: The site of perception of light on plants for flowering is **leaves**.
