Question

Do anaerobic respiration in plants yield lactic acid

Answer 1

first things
plant don't respire anaerobically
not all anaerobically respiration cause lactic acid formation some yield ethanol.

Answer 2

Anaerobic respiration takes place in the absence of oxygen.when plants respire anaerobically,ethyl alcohol (C2H5OH) is produced as one of it's product.but when anaerobic respiration take place in animal, lactic acid(C3H6O3) is produced.So plant can't yield lactic acid during it's respiration.
