The use of the isotope 32P as a tracer element in the study of invasion and lysis of bacteria by viruses has shown that bacteriophage protein enters the bacteria. Phosphorus-32 is a radioactive isotope of phosphorus, such that the nucleus of phosphorous-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorous, phosphorous-31.
Non-green plants cannot make their own food because they do not have chlorophyll in their leaves which breaks down carbon dioxide and water molecules thus do not produce glucose(food).
