Place of aerobic respiration to release energy
What is the function of ribosomes?
Site of protein synthesis
What is the function of the cytoplasm?
Jelly like substance where chemical reactions occur
What is the function of the cell membrane?
Control the movement of substance going in and out of the cell

Focus the image
What does the iris/diaphragm do?
Controls the amount of light onto the stage/specimen
What is the equation for magnification?
