Cell structure and division:
Eukaryotic cells:
Eukaryotic cells are cells that store their genetic information within a double-membrane bound nucleus. They also have o
are membrane bound and have a DNA genome.
The organelles within eukaryotic cells vary depending on the type of organism they’re a part of, cells within multice
organisms can also vary to each other depending on a cells function, for example a typical human skin cell will cont
more organelles than a human red blood cell.
Some organelles are a universal feature of typical eukaryotic cells though, such as the nucleus, mitochondria and ri
which are found in all four animal, plant, fungal and algal cells.
