The aggregate morphology permits re-establishment of the cell-cell contacts normally present in tissues; therefore, cell function and survival are often enhanced in aggregate culture. Because of this, cell aggregates may also be useful in tissue engineering, enhancing the function of cell-based hybrid artificial organs or reconstituted tissue ...

Cells are divided into two main classes, initially defined by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and ...

Cell Wall (plant cells only): Plant cells have a rigid, protective cell wall made up of polysaccharides. In higher plant cells, that polysaccharide is usually cellulose. The cell wall provides and maintains the shape of these cells and serves as a protective barrier. Fluid collects in the plant cell vacuole and pushes out against the cell wall.
