Here's a breakdown:
* Nucleus: The control center of the cell, containing the cell's DNA.
* Membrane-bound organelles: Structures within the cell that are enclosed by membranes, allowing for specialized functions. Examples include:
* Mitochondria: Powerhouses of the cell, responsible for energy production.
* Golgi apparatus: Processes and packages proteins and lipids.
* Endoplasmic reticulum: A network of membranes involved in protein synthesis and lipid metabolism.
* Lysosomes: Contain enzymes for breaking down waste materials.
* Vacuoles: Storage compartments for water, nutrients, and waste.
Eukaryotic cells are found in all organisms except for bacteria and archaea, which are prokaryotic cells. Prokaryotes lack a nucleus and membrane-bound organelles.
