As schizont development proceeds further cycles of division cause the appearance of mutiple separate areas chromatin that will eventually form the merozoies, although at this stage they still lie within a single cytoplasmic mass.

How does schizont appearance change during their development?
THE INITIAL ASEXUAL DIVISION
The cartoon image (A) shows the division of chromatin into two masses within a continuous blue parasite cytoplasm (indiviual merozoites are not really distinguishable here). A clinical image of a parasite at this developmental stage (P.ovale with well shown James'dots) is shown in panel (B).
IMMATURE SCHIZONT APPEARANCES
The cartoon image (A) shows the further division of chromatin into many discrete massed within the blue parasite cytoplasm (indiviual merozoites are still not distinguishable). A clinical image of a parasite at this developmental stage (again from P.ovale with well shown James'dots) is shown in panel (B).
