Here's why:
* Eukaryotic cells are complex cells that have a true nucleus and other membrane-bound organelles. These internal membranes compartmentalize the cell, allowing for specialized functions to occur in different areas.
* Prokaryotic cells, on the other hand, are simpler cells that lack a nucleus and other membrane-bound organelles. They have a single, circular chromosome located in a region called the nucleoid, but it is not enclosed by a membrane.
Examples of eukaryotic cells:
* Animal cells
* Plant cells
* Fungi cells
* Protists
Examples of organelles found in eukaryotic cells:
* Nucleus
* Endoplasmic reticulum
* Golgi apparatus
* Mitochondria
* Lysosomes
* Chloroplasts (in plant cells)
The presence of internal membranes is a defining characteristic of eukaryotic cells and allows for a much higher level of complexity and organization compared to prokaryotic cells.
