Explanation / Answer

1 Members of the Monera kingdom lack chloroplast,a nucleus and mitochondria all of these

2 the autotrophic monerans are cyanobacteria

3 Bacteria reproduce by binary fission

4 Most bacteria are chemoheterotrophs that is they use the electrons from hydrogen atoms in organic compounds as their energy source
