Separate small pieces of onion epidermis, keep them in watch glass containing Neutral
red solution ( 0.005 % ) for 10 min. Rinse thoroughly with D.W. (H2O ), then examine
microscopically .
1- Does the cells, stained ?
2- Which part of the cells are stained more than the other ?
3- Does the cells died or remain alive at the end of the experiment. Give reason for both cause
