Individual parts perform very specific functions.
They each have different jobs or specializations. The same is for your heart and for your stomach.
organelle
Eukaryotic cells contain membrane bound compartments, prokaryotic cells don't. Membrane bound compartments form organelles. Prokaryotes are a group of organisms made up of both bacteria and archaea, which you may not have studied- they used to be known as archaeabacteria as people thought they were a kind of bacteria, but current scientific opinion is that they're separate. So... no, it's not only bacteria that don't have organelles, archaea don't either.
bateria cells, otherwise known as prokaryotic cells.
organelles
Plastids are the main organelles that store these compounds. All plastids are related in origin and many can become other types given the right circumstances. Photosynthesizing plastids are known as chloroplasts (the most commonly known type) Plastids for pigment storage are known as chromoplasts Starch storage plastids are called amyloplasts. However, some pigments in plants, such as the pink/purple/blue anthocyanins are usually stored in the vacuole of the cells.
Specialized cells that have no organelles are known as Prokaryotes.
They are all enclosed by a membrane.
The "powerhouses" of animal cells are the mitochondria. Within the mitochondria. These specialized organelles produce a cell energy currency known as ATP (adenosine phosphate).
organelle
Erythrocytes are cells that contain hemoglobin. These are commonly known as red blood cells.

Vacuoles
Every single type of cell does except bacteria (kingdom monera). Animal, plant, fungus and protists all do. Organisms made up of these cells, cells with a nucleus and organelles are Eukaryotes.
The cyto plasm is the liquidy substance that is in between the cell membrane and the nucleus. It is known to contain vital organelles (organs) of a cell. This is what i learned after a quarter on cells.
