What is a cell?

A cell is composed of a selectively permeable plasma membrane filled with cytoplasm, and containing several intracellular structures. The cytoplasm is a watery solution of organic molecules, gasses and minerals, and is the site of chemical reactions within the cell.

The intracellular structures include the :

The anatomy of a eukaryotic cell

The anatomy of a single eukaryotic cell

Also found within the cytoplasm is the nucleus, which is the control centre of the cell. Filled with nucleoplasm within a selectively porous nuclear membrane, the nucleus contains the deoxyribonucleic acid (DNA) and chromatin, which together form chromosomes during mitosis.
