Ans. The differences in anaerobic respiration between plants and animals are: a. In plants, the end products are ethanol and CO2. In animals, the end product is lactic acid. b. In plants, the accumulation of ethanol may kill the plant. In animals, the lactic acid cannot cause death but may lead to minor muscle cramps that can be cured with a hot water bath or a massage. c. In plants, CO2 gets released, but in animals, no CO2 is released.
