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.

1.0 mm

Plant Cells

• This is a view of plant 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:

cell wall vacuole nucleus

• Calculate the size of each cell using the information given; record next to your sketch.
