The cytoplasm contains a variety of tiny yet distinct structures known as organelles that carry out specific tasks.
For the cell to function normally, they coordinate and work effectively.
The cell has a variety of organelles that are divided into three groups based on whether or not they have a membrane:
organelles without membrane
single membrane-bound organelles
double membrane-bound organelles.
Non-membrane-bound cell organelles include the cell wall, ribosomes, and cytoskeleton. They can be found in both eukaryotic and prokaryotic cells.
Only eukaryotic cells have the double membrane-bound organelles nucleus, mitochondria, and chloroplast in addition to the single membrane-bound organelles vacuole, lysosome, Golgi apparatus, and endoplasmic reticulum.
