White is an achromatic color, a color without hue. Light with a spectral composition that stimulates all three types of the color sensitive cone cells of the human eye in nearly equal amounts appears white.
The nucleolus is contained within the cell nucleus. The nucleolus (/nuËËkliËÉµlÉs/ ; plural nucleoli /nuËËkliËÉµlaÉª/) is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly.he nucleolus is contained within the cell nucleus.

Nuclear structure is studied in contemporary nuclear physics by means of high-energy particles, and the fundamental properties of elementary particles are established through the study of the radioactive decay of nuclei.
