The structure of albuminous cells is adapted to their function in protein synthesis and secretion. They typically have an extensive rough endoplasmic reticulum, which is studded with ribosomes. This structure is necessary for the translation of mRNA into protein. The Golgi apparatus in these cells is also well-developed, facilitating the processing, modification, and packaging of proteins for secretion. Additionally, these cells often contain numerous secretory vesicles that store the synthesized proteins before they are released.
