It is clear that Genesis mentions ONLY plants and animals, so it infers the Two Kingdom System.
The two kingdom system was abandoned because organisms could not be classified appropriately into only two kingdoms. Modern classification systems recognize 6 kingdoms organized into 3 domains. I don't think Genesis was intended to be a reference book on classification systems.
It is clear that none of the six different systems of Taxonomy is perfect, and the choice to use one or the other is subjectively a decision of the individual who might so do for purposes that seem satisfactory for their intend use.
No, it is true. No taxonomic system is perfect, not because of subjectivity but because of the extreme complexity and diversity of living things.
Bacteria which has cell walls falls into the category of the Plant Kingdom using the Two Kingdom System.
Wrong. Most bacteria use peptidoglycans in their cell walls while plants use cellulose. Two different structures.
The animals alway breath in oxygen,
You do realize that plants "breath in oxygen" too, right? Plants, animals and fungi all perform cellular respiration using oxygen.
separated by the respiration of CO2 in the former
Did you know that plants do not respirate CO2? They produce sugars through photosynthesis by fixing atmospheric CO2.
and use of chloroplast for photosynthesis.
There are some animals as well that use chloroplasts to fix carbon. Additionally several Protista do as well. Is a Euglena a plant or an animal?
and must ingest protein and sugars they can not manufacture.
Most bacteria (not all) are hetrotrophs (need to ingest food) so would they be classified as an animal? But they have a cell wall ... so maybe a plant?
Honestly, I am not sure what point you were trying to make here, but maybe you should learn some of these introductory level biological concepts before you try to tackle more difficult concepts

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for. But until the end of the present exile has come and terminated this our imperfection by which "we know in part," I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
