nuclei
Hearts of cells
Nuclei is the plural of nucleus.
A nucleus is the central, essential part of something—the core around which other elements gather.
In biology, the nucleus is the membrane-bound structure in a cell that contains genetic material.
In physics, the atomic nucleus is the dense center of an atom, containing protons and neutrons.
In astronomy, a comet's nucleus is its solid core.
The nuclei of these cells showed abnormalities.
