For a living organism to live, grow and reproduce, it must have at least 3 systems is place SIMULTANEOUSLY.
1) The organism must have developed a simple RESPIRATORY SYSTEM. (be able to breath)
2) The organism must have developed a simple DIGESTIVE SYSTEM. (TO EAT)
3) In order to pass on this to the next generation, the organism must have a simple REPRODUCTIVE SYSTEM. (to multiply)
Now because I call each of these "simple systems", there are by no means simple, because even the simplest single cell animal is made up of THOUSANDS OF MOLECULES.

1/ Nope, plants don't have a "respiratory system", nor do bacteria. In fact, if memory serves, only multicellular animals have respiratory systems. Methinks you are confusing respiration (metabolic) with breathing.
2/ Nope, most plants absorb minerals dissolved in water. Photosynthesis can hardly be described as a "digestive" system. Not to mention most single celled organisms.
3/ Ta-Da! Mostly right, partly wrong. It doesn't need a reproductive system, it just needs to be able to reproduce. Bacteria don't have reproductive systems.
