Animal Cells – 100x This is a view of animal cells under low power. 2.0 mm This is a view of animal cells under low 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.
Animal Cells – 400x 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. 0.5 mm
Plant Cells – 100x This is a view of plant cells under high power. 2.0 mm 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.
