Detailed explanation-1: -In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.
Detailed explanation-2: -Membrane-bound organelles, however, are only found in eukaryotes. These organelles are contained by an outer barrier called a membrane. Examples of membrane-bound organelles include the Golgi complex, the endoplasmic reticulum, lysosome, chloroplast, or mitochondria.
