Animal Cells
• This is a view of animal cells
under high power.
• The slide has been stained to
make individual organelles
more visible.
• Sketch these cells exactly as
you see them (in color).
• Label the following structures
on your diagram:
plasma (cell) membrane
cytoplasm
nucleus
• Calculate the size of each cell
using the information given;
record next to your sketch.
