Question

What are cell organelles? Give three examples.

Answer 1

A membrane-bound compartment or structure in a cell that performs a special function. Supplement. A eukaryotic cell contains manyorganelles, for example, the nucleus, endoplasmic reticulum, golgi apparatus, mitochondria, and chloroplast 

Answer 2

In cell biology, an organelle (/ɔːrɡəˈnɛl/) is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers.

The name organelle comes from the idea that these structures are a part of cells, like what an organ is to the body (hence the name organelle, the suffix -elle being a diminutive). Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells. While prokaryotes do not possess organelles per se, some do contain protein-based bacterial microcompartments, which are thought to act as primitive organelles.
