Biological Concept & Syllabus Guide
Light is excluded from a water culture experiment in order to prevent growth of algae which will alter the composition of the solution. Light is typically excluded from a water culture experiment to prevent the growth of algae because algae require light for photosynthesis and therefore cannot grow without it; this is a key reason why researchers often cover their culture vessels with foil or keep them in dark conditions when studying plant roots in a water culture setup.
