Mangroves exhibit unique cellular and physiological adaptations that enable them to survive in high-salinity environments. Discuss. How can these adaptations be leveraged to address agricultural challenges in saline-prone regions?
Tips for your answer
- Start with the core adaptation
- Briefly explain why salinity is a stress factor for plants and highlight key mangrove adaptations such as thick cell walls, small epidermal cells, and salt exclusion or secretion mechanisms.
- Use 1–2 clear examples
- Mention root-level salt filtration and leaf-level salt secretion to show diversity in mangrove survival strategies without going into excessive biological detail.
- Link to applied relevance
- Conclude by connecting these adaptations to the possibility of engineering salt-tolerant crops to combat soil salinization and ensure agricultural sustainability.
