The plant reorganizes its internal cells during extreme heat. Mitochondria move closer to chloroplasts and multiply in number. Chloroplasts shift shape from ovals to cup-like structures. This arrangement boosts photosynthesis and energy efficiency. Heat-response genes are activated to repair and protect cells.
