We just got through with a lab and we looked at ecoli, anabaena. There first section is prokaryotic cells and the question is did all living cells you saw in the lab contain mitochondrion. I know mitochondrion is the energy powerhouse of the cell but see nowhere in the first section where it discusses mitochondrion or is it labeled on the microscope drawings in the text. I would guess that the answer would be yes because they are the energy powerhouse as mentioned abovce but am unsure.
E Cole and anabena are prokaryotic cells. Prokaryotes are different from eukaryotes in that they (the prokaryotes) do NOT have any organelles inside the cell. (That is, the DO NOT have nuclei, endoplamic reticula or mitochondria).
A chemical signal that acts as a messenger is a ?
why are they important
