Spherical round -shaped bacterial cells
WebBacterial cell division is the result of a productive round of the cell cycle to yield two daughter cells. The cell cycle is highly coordinated in Caulobacter crescentus where it is driven by a cell cycle gene-regulatory network that coordinates gene expression with the major cell cycle events such as chromosome replication and cell division. WebFor example a bacterial cell. Eukaryotic cells have a defined nucleus. For example an animal and a plant cell. A plant cell contains a chloroplast to perform photosynthesis however an animal cell lack it. A bacterial cell can be of any shape, whereas a plant cell is rectangular and an animal cell is oval or spherical.
