The correct Answer is:
To solve the question regarding the main functions of root systems, we will analyze each option provided. ### Step-by-Step Solution: 1. **Identify the Functions of Roots**: - Roots are essential parts of a plant that serve multiple functions. 2. **Evaluate Option (a)**: - **Absorption of water & minerals**: - Roots absorb water and essential minerals from the soil. This is a fundamental function of roots as they provide the necessary nutrients for the plant's growth and development. - **Conclusion**: This option is correct. 3. **Evaluate Option (b)**: - **Providing a proper anchorage to the plant**: - Roots anchor the plant securely in the soil, preventing it from being uprooted by wind or water. This stability is crucial for the plant's survival. - **Conclusion**: This option is also correct. 4. **Evaluate Option (c)**: - **Maintaining the temperature & pressure of the plant**: - This function is primarily associated with the stem and leaves, which help regulate temperature and pressure through transpiration and other processes. - **Conclusion**: This option is incorrect. 5. **Evaluate Option (d)**: - **Gaseous exchange**: - Gaseous exchange occurs mainly through the leaves, specifically through structures called stomata. Roots do not play a direct role in this process. - **Conclusion**: This option is incorrect. 6. **Final Conclusion**: - The correct functions of the root systems are (a) Absorption of water & minerals and (b) Providing a proper anchorage to the plant. Therefore, the correct answer is options (a) and (b). ### Final Answer: The main functions of the root systems are (a) Absorption of water & minerals and (b) Providing a proper anchorage to the plant. ---
