Bacteria and blue-green algae are both primitive prokaryotes that live on earth now, as well as long time ago. Just recently they have changed blue green algae or cyanobacteria to be in the kingdom prokaryotes.

Because these are the simplest organisms that could have existed. Every organism starts from the smallest and simplest living subunit and then develops further.

Do bacteria have plastids?

Some bacteria have chloroplasts. For example, cyanobacteria. They are photosynthetic bacteria No, bacteria do not have chloroplasts because they are prokaryotic which means they can't have membrane bound organelles other than ribosomes.. Chloroplasts are membrane bound organelles. As for the cyanobacteria, they are indeed photosynthetic, but they still don't have chloroplasts. It is somewhat misleading. They were once called blue-green algae (they even fooled earlier scientists) but are now considered bacteria because they lack a membrane bound nucleus and chloroplasts.
