Expert Answer:

Cell is an autonomous self-replicating unit that may exist as functional independent unit of life (as in unicellular organism), or as sub-unit in a multicellular organism (as in plants and animals) that is specialized into carrying out particular functions towards the cause of the organism as a whole.
There are two distinct types of cells: prokaryotic cells (e.g. bacterial cells) and eukaryotic cells (e.g. plant or animal cell).
 
Cell-organelle is a membrane-bound compartment or structure in a cell that performs a special function.
Organelles in eukaryotic cells: Nucleus, endoplasmic reticulum, golgi apparatus, mitochondria, vacuoles, lysosome, centrosome and chloroplast (plastid)
 
Organelles in prokaryotic cells - Carboxysome (a protein-shell compartment for carbon fixation in some bacteria), chlorosome (a light harvesting complex in green sulfur bacteria), magnetosome (found in magnetotactic bacteria) etc.
