The correct Answer is:
To answer the question "A physiological xerophyte is," we need to understand the concept of xerophytes and identify examples of physiological xerophytes. ### Step-by-Step Solution: 1. **Define Xerophytes**: - Xerophytes are plants that have adapted to survive in environments with very little water. They have special adaptations that allow them to conserve water and withstand drought conditions. 2. **Types of Xerophytes**: - Xerophytes can be classified into two main categories: - **Morphological Xerophytes**: These plants have physical adaptations such as thick cuticles, reduced leaf surface area, and deep root systems. - **Physiological Xerophytes**: These plants have internal physiological adaptations that help them manage water loss and utilize water efficiently. 3. **Identify Physiological Xerophytes**: - Physiological xerophytes have adaptations that allow them to tolerate high salinity and arid conditions. They might not necessarily look like typical desert plants but have mechanisms to survive in such environments. 4. **Examples of Physiological Xerophytes**: - The transcript mentions several examples: - **Salicornia**: A succulent, halophytic flowering plant that grows in saline areas such as beaches and salt marshes. It is a classic example of a physiological xerophyte. - Other examples mentioned include **Euphorbia**, **Salvia**, and **Agave**, which also have adaptations to survive in low water availability conditions. 5. **Conclusion**: - Therefore, a physiological xerophyte is a plant that has developed internal adaptations to survive in environments with limited water availability, with **Salicornia** being a prominent example.
