WebNormally, Na+ concentration is higher outside the cell than inside. So Na+ ions flow down their gradient into the egg and the plasma membrane depolarizes (positive charges neutralize the more negative charge inside the egg cytoplasm.) This depolarization causes the FAST BLOCK TO POLYSPERMY. WebEosin is an acidic dye: it is negatively charged (general formula for acidic dyes is: Na + dye -). It stains basic (or acidophilic) structures red or pink. This is also sometimes termed 'eosinophilic'. Thus the cytoplasm is stained pink in the picture below, by H&E staining. Haematoxylin can be considered as a basic dye (general formula for ...
