Vedclass · Answer

(A) In centrolecithal eggs,such as those found in insects,the yolk is concentrated in the center of the egg. During superficial cleavage,the nuclei divide repeatedly without cytoplasmic division,and these nuclei migrate to the periphery. Subsequently,the cytoplasm surrounds each nucleus to form cells. As a result,a layer of cells is formed around the central mass of yolk. Therefore,the yolk is surrounded by the cells.
