The main organelle that cannot be found in a prokaryote is the nucleus. Prokaryotic cells, such as bacteria, lack a membrane-bound nucleus and instead have their genetic material organized in a nucleoid region. Additionally, prokaryotes do not possess other membrane-bound organelles like mitochondria or endoplasmic reticulum, which are characteristic of eukaryotic cells.
Main reason is it is found inside a cell.But according to endosimbiotic theory mitochondra is a pre prokariyotic cell.
Chloroplast
The organelle in plants that participates in cellular respiration is endoplasmic reticulum, and is also the organelle in both plants and animals, that is the main components for cellular respiration.
There is one main organelle that is involved in phagocytosis. The organelle involved is the cell membrane due to transportation.
Since you asked about the main organelle, singular, I will have to say....The membrane bound nucleus that eukaryotes have and prokaryotes do not.
Golgi cannot be seen in prokariyotes. Main examples are bacteria and Archebacteria.
It is the nucleus .Prokariyotes lack a nucleus.
One circular main chromosome and, perhaps, a number ( 1 to 3 ) of circular plasmids.
The main ions found inside a neuron are potassium and organic anions. The organic anions cannot cross the cell membrane but potassium ions can. It is the diffusion of potassium ions out of the cell which is the main cause of the resting membrane potential.
The Golgi Appartus is an organelle found in Eukaryotic cells. It's main job is to package and stare proteins and lipids.
Main reason is it is found inside a cell.But according to endosimbiotic theory mitochondra is a pre prokariyotic cell.
Round , rod and spiral .
Main organelle used in cellular respiration is Mitochondria dude.
