The spelling of the word "albuminous cell" can be a bit tricky, but the IPA phonetic transcription can help. In IPA, it is pronounced /ælˌbjuːmɪnəs ˈsɛl/. The first part of the word, "albuminous," is spelled with "b" rather than "p" despite it being pronounced with a bilabial nasal /m/ because it derives from the Latin "albumen" meaning "white of egg." The second part, "cell," is simply spelled as it sounds. Together, the word refers to a cell containing albumin protein.
An albuminous cell, also known as a secretory cell or protein-secreting cell, is a type of specialized cell that produces and releases large amounts of albumin or other proteins. Found in various multicellular organisms, including plants and animals, these cells play crucial roles in maintaining the body's overall health and functionality.
In animals, albuminous cells are commonly found in the liver, pancreas, and mammary glands. In the liver, they synthesize albumin, a major plasma protein that helps regulate osmotic pressure and transport insoluble substances. In the pancreas, albuminous cells produce digestive enzymes, such as trypsin and chymotrypsin, which aid in the breakdown of proteins during digestion. In mammary glands, these cells are responsible for producing milk proteins, including casein and lactalbumin, vital for the nourishment of newborns.
In plants, albuminous cells are present in specific structures like the endosperm of seeds. These albuminous cells are responsible for synthesizing and storing proteins, providing essential nutrients to the developing embryo as it germinates. Furthermore, they offer protection against pathogens, toxins, and environmental stresses, contributing to the overall survival and growth of the plant.
Overall, albuminous cells are integral components of various biological processes. Their ability to produce and release specific proteins ensures the maintenance of bodily functions and the completion of vital developmental stages in organisms.

The word "albuminous" comes from the Latin word "albumen", meaning "white of an egg". This term is used to refer to the protein content found in egg white. When combined with the word "cell", which derives from the Latin word "cellula" meaning "small room", the term "albuminous cell" is formed. "Albuminous cell" refers to a cell that contains or produces albumen or a substance with similar properties as egg white.
