Bacteria Cells are cells that make up bacteria. It is not uncommon for bacteria organisms to be single cellular. Bacteria cells are prokaryotic cells. This means that they do not have a nucleus and they do not have any membrane bound organelles. They are also smaller than eukaryotic cells and have evolved more recently.
Bacteria cells have a membrane, cryoskeleton, cytoplasm, and DNA much like plant and animal cells. Bacteria cells however, do not have pili, a capsule, or plasmids. The pili are hair like structures that allow the bacteria to clasp onto a surface to vaccum up essential nutrients. This is similar to the hairs on the legs of insects and spiders that allow them to attach to surfaces. The capsule is a thick covering of the cell's cell wall to protect the cell when it is in a dormant state in hostile environments.
In recent years, scientists have found out methods to genetically engineer bacteria cells to do certain tasks. Scientists have been able to remove the DNA in the cell's plasmid. The DNA is then replaced by human DNA, and human genes intertwine with the bacteria's. Depending on the type of gene, the bacteria can produce substances needed for any medical or other reasons.
