Q

how is mitochondria adapted to its function

A

Mitochondria have a double membrane structure, with an inner layer with many folds to create a high surface area. This provides more space for more metabolising proteins and therefor they are able to create more energy at one time.

Q

how is the nucleus adapted to its function

A

The shape of the nucleus is mostly round, it may be oval, disc shaped depending on the type of cell. … The envelope helps to maintain the shape of the nucleus and assists in regulating the flow of molecules into and out of the nucleus through nuclear pores.
