Egg Cytoplasm

The cytoplasm is one organelle that has been labeled feminine. The cytoplasm/nucleus being labeled as feminine/masculine follows the example of egg/sperm being gendered; both cytoplasm and egg are considered nonresistant to the efforts and pursuits of the active nucleus and sperm. The "passivity of the egg becomes the passivity of the cytoplasm. The egg cell has a large cytoplasm because it the cytoplasm provides the egg with nutrients after fertilization. Fertilization can initiate radical displacements of the egg’s cytoplasmic materials. While these cytoplasmic movements are not obvious in mammalian or sea urchin eggs, there are several species in which these rearrangements of oocyte cytoplasm are crucial for cell differentiation later in development.
