Which has a prokaryotic cell. a: beet root b: human kidney c: rose thorn d: lactobacillus

Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Prokaryotes include two groups: bacteria and another group called archaea. Having organelles is a big deal for a cell.

Prokaryotic cells have no nucleus and they are small and simple.

while, eukaryotic cells have a nucleus and are large and complex as

opposed to prokaryotic.

so the answer is "B", "Lactobacillus"
