Which kingdom would a single celled organism with a nucleus, cell wall and chloroplast belong?

that kingdom would belong to the primary producers also known as autotrophs (they produce their own resource) as they are single celled organism (as we are too) that have a nucleus and a cell wall that is contained of cellulose that only plants, algae, and fungi could have, it provides protection for the cell. and the chloroplast are only in photosynthetic organism which are plants (and some other creatures like some bacteria and protists) where they take light energy from the sun into usable chemical energy.
