All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal ...

All of these organelles are located in the eukaryotic cell's cytoplasm. Although only eukaryotes carry membrane-bound organelles, recent evidence suggests that both eukaryotes and prokaryotes can ...
