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.
