Evidence soon accumulated that the cytoplasm of the egg stood for much in the differentiation of the embryo. Food particles, wastes, and other substances may also be present in the cytoplasm. The cytoplasm is the outer and softer part, the substance of the body of the cell. The general mass of material forming the cell is termed cytoplasm. cytoplasm | American Dictionarycytoplasm noun[ U ] us/ˈsɑɪ·t̬əˌplæz·əm/ biology the substance inside a cell which surrounds the cell's nucleus (= central part) Examples of cytoplasmcytoplasm Microtubules were organized around condensed chromosomes after the nucleus had been transferred into any of the three types of cytoplasm.

Each lateral canal consists of an elongated cell embedded in the cytoplasm of the lateral hypodermal cord. The oocytes surrounded by compact cumulus and with evenly granulated cytoplasm were selected. Only oocytes with evenly granulated cytoplasm surrounded by multiple layers of compact cumulus cells were used in all the experiments. Only oocytes with one or more complete layers of unexpanded cumulus cells and an evenly granulated cytoplasm were selected. Only oocytes with one or more completed layers of unexpanded cumulus cells and evenly granulated cytoplasm were used. Most morphological alterations were presented by the vacuolization of embryonic cells, disintegrated cytoplasm, swollen mitochondria and dilatation in rough endoplasmic reticula. Anteriorly, the granules are much more numerous, almost filling the cytoplasm, surrounding small blind-ending canals. Parenchymatous cells that turned into sclereids included prominent nuclei and dense cytoplasm, although their walls were thick and showed distinct pit fields (fig. 9). Xenopus oocyte maturation: cytoplasm alkalization is involved in germinal vesicle migration. These examples are from corpora and from sources on the web.
