Explain how fire and extreme weather conditions (heat, drought) affect sugarcane plants, and how they recover after the rains. Focus on the specific plant parts involved and the physiological processe

Morning Akram — let's get this done. a) i) Fire damage affected the sugarcane plants by: • Burning the older leaves, which are crucial for photosynthesis, thus reducing the plant's ability to produce food. • Damaging the outer stem tissues, which provide protection and support, potentially exposing inner tissues to further harm. ii) High temperature and drought affected the sugarcane plants by: • Causing excessive water loss through transpiration due to high temperatures, leading to dehydration. • Limiting water uptake and nutrient transport due to lack of rainfall, resulting in wilting and reduced metabolic activity. • Inhibiting photosynthesis as stomata close to conserve water, reducing carbon dioxide intake. b) The sugarcane plants managed to regenerate and grow after the rains because: • The underground nodes (part of the rhizome or underground stem) were protected from the fire, high temperatures, and drought. • These nodes contain dormant buds with meristematic tissue, which are capable of developing into new shoots and roots. • When rains resumed, sufficient water became available, triggering these dormant buds to sprout and grow new shoots, utilizing stored food reserves in the underground parts.
