Fat droplets are not cell organelles. They are storage structures that are found within cells, especially adipose cells. These droplets are made up of triglycerides, which are fats that have been stored for future use. Cell organelles, on the other hand, are specialized structures within cells that perform specific functions. Examples of cell organelles include the nucleus, ribosomes, Golgi body, endoplasmic reticulum, mitochondria, and chloroplasts (in plant cells).
