in complex multicellular organisms, eukaryotic cells become specialised for specific functions
These specialised eukaryotic cells have specific adaptions to help them carry out their functions
for example the structure of a cell is adapted to help it carry out its function (why specialized eukaryotic cells can look extremely different from each other)
structural adaptions include the shape of the cell and the organelles the cell contains / or doesnt
example of specialised cell =
muscle cells are very active so contain lots of mitochondria in order to produce ATP
Red blood cells have a biconcave shape and no nucleus to maximize space to carry oxygen. They also have lots of haemoglobin
Cell Organisation:
specialised cells are organised into tissues, tissues into organs and organs into organ systems
Tissues (e.g. muscle tissue, xylem tissue)
Organs (e.g. the animal heart or plant leaf)
Organ systems (e.g. the female reproductive system)
