3. Reactive Oxygen Species (ROS): During photosynthesis, ROS are generated, prompting plants to produce antioxidants as a defense mechanism.
4. Nutrient Uptake: Photosynthesis enhances the uptake of minerals, which are vital for synthesizing various antioxidants.

Light Intensity Effects

Light intensity plays a crucial role in the antioxidant production of microgreens, directly impacting their nutritional value. I’ve observed that higher light exposure can enhance photosynthesis, resulting in increased levels of antioxidants. This relationship is evident when comparing microgreens grown under varying light conditions.

Light Intensity (µmol/m²/s)	Antioxidant Level (mg/g)	Microgreen Variety
