Chromatin -- found only in the cells of eukaryotic organisms -- is the complex of DNA and a specialized suite of of proteins that are organized in beads, wrapped with DNA, and the string folded, at multiple scales, to allow the DNA to be packaged into the neat nuclear structures called chromosomes that we see through the microscope. Cells come from preexisting cells. Cells can perform all life processes. All living things are made of cells. The cells in a multicellular organism are specialized to perform a particular function. A group of related cells that work together make up _____.
In order for a cell to become specialised, a process called Differentiation occurs, where unspecialised cells (called Stem Cells) produce cells with specialised structures. All multicellular organisms contain some form of Stem Cells. These are the cells that divide to replace damaged or old tissue, or new cells for growth.
