The stages of mitosis are in the following order:

Prophase, metaphase, anaphase, telophase

A cell wall and a cell membrane

Two nuclear membranes and a 2 nucleoli appear.

Cells need to stay small so that:

The surface area is big enough for diffusion of materials

Active transport moves particles:

Against the concentration gradient

Biology class is soooo fantastic because

All of the above and SO much MORE
