The correct Answer is:
To determine which plant is classified as a Long Day Plant (LDP), we need to understand the concept of photoperiodism and the characteristics of different types of plants based on their light requirements. ### Step-by-Step Solution: 1. **Understand Photoperiodism**: - Photoperiodism refers to how plants respond to the lengths of day and night. It plays a crucial role in the flowering process of plants. 2. **Categories of Plants**: - Plants can be broadly classified into three categories based on their light requirements: - **Long Day Plants (LDP)**: These plants require longer daylight periods (more than the critical duration) and shorter night periods (short scotoperiod). - **Short Day Plants (SDP)**: These plants require shorter daylight periods (less than the critical duration) and longer night periods (long scotoperiod). - **Day Neutral Plants (DNP)**: These plants are not affected by the length of day or night and can flower regardless of the photoperiod. 3. **Examples of Long Day Plants**: - Some common examples of Long Day Plants include: - Spinach - Wheat - Oat - Sugar beet - Radish - Lettuce 4. **Identify the Correct Answer**: - From the options provided, we need to identify which plant is a Long Day Plant. According to the information, **Spinach** is specifically mentioned as an example of a Long Day Plant. 5. **Conclusion**: - Therefore, the correct answer to the question "Which plant is LDP?" is **Spinach**.
