Correct Experimental Inquiry: Which Wavelengths of Light Drive Photosynthesis? Theodor Engelmann was one of the firs t s c ientis ts to us e the mic ros c ope as an ex perimental tool rather than as s imply an obs erv ational tool. He was als o the firs t s c ientis t to des c ribe c hemotax is : the mov ement of bac teria toward regions where s pec ific c ompounds are mos t c onc entrated. In the early 1880s , s c ientis ts already k new that plants and algae us ed s unlight to produc e s ugars , with ox y gen (O2) as a by produc t. They als o k new that s unlight was a mix ture of many c olors (the v is ible s pec trum) and that plants and algae abs orbed more light in the red and blue parts of the s pec trum than in the green part of the s pec trum. Engelmann was interes ted in determining whic h c olors (or wav elengths ) of light were mos t effec tiv e in driv ing photos y nthes is in green algae. He dev is ed a s imple y et elegant ex periment us ing aerotac tic (ox y gen­s eek ing) bac teria to ans wer this ques tion. (Aerotax is , or mov ement toward ox y gen, is one form of c hemotax is .)
