Structures in eukaryotic cells
WebUnlike prokaryotic cells, eukaryotic cells have: 1) a membrane-bound nucleus; 2) numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others; and 3) several, rod-shaped chromosomes. Because a membrane surrounds eukaryotic cell’s nucleus, it has a “true nucleus.” WebA eukaryotic cell is a compartmentalised cell that contains membrane-bound organelles. The organelle that differentiates it the most from prokaryotes and is considered a key feature of eukaryotic cells is the nucleus. There are four main types of eukaryotic cells: plant, animal, fungi and protozoan cells.
