BACTERIAL CELL (Prokaryotic Cell )Parts and Function

bacteria

1. BACTERIAL CELL

2. Cell Envelope – MADE UP OF three layers: the interior cytoplasmic membrane, the cell wall, and an outer capsule.

3. Capsule - a third protective covering IN BACTERIAL CELL made up of polysaccharides (complex carbohydrates)

4. Escherichia coli Streptococcus pneumoniae.

5. Cell Wall - composed of peptidoglycan, a protein-sugar (polysaccharide) molecule.

6. Hans Christian Gram

7. Cytoplasmic Membrane - A layer of phospholipids and proteins THAT encloses the interior of the bacterium.

8. Cytoplasm - is where the functions for cell growth, metabolism, and replication carried out. It contains cell structures such as ribosomes, chromosome, and plasmids.

9. Flagella - are hairlike structures that provide a means of locomotion for those bacteria that have them.

10. Pili - small hairlike projections emerging from the outside cell surface.

11. Nucleoid - is a region of cytoplasm where the chromosomal DNA is located.

12. Ribosomes - are similar to those of eukaryotes, but are smaller and have a slightly different composition and molecular structure.
