Bacteria+Cells

=Bacteria Cells=

=EX... Amoeba and paramecium= =They are Prokaryotic cells.=

The cells of bacteria are different from those of plants and animals in many ways, the most obvious of which is that bacteria lack a nucleus and other membrane-bound organelles (except ribosomes). Unlike animals and plants, bacteria have pili, flagella, and most have a cell capsule.

Bacterial cells include the following:


 * __cell wall__ - A thin membrane located outside the plasma membrane and within the capsule.


 * __flagellum__ - A long whip-like structure used for locomotion (movement). Some bacteria have more than one flagellum.


 * __plasma membrane__ - A permeable membrane located within the cell wall. It serves many functions for the cell, including energy generation and transport of chemicals.


 * __ribosomes__ - Small organelles composed of RNA-rich granules that are sites of protein synthesis. The ribosomes are located within the cytoplasm.
 * Chloroplastsno, bacteria do not have chlorplasno because they are prokaryotic, and can not have membrane bound organelles other than ribosomes
 * Cilia- Since bacteria are prokaryotes they do not have cilia they have flagella
 * Cytoskeleton- is the “skeleton” on the cell it is contained within the cell’s cytoplasm and is made out of protein

> = Golgi- No. Prokaryotic cells, or bacteria cells, do not have a Golgi body =
 * Flagella- Some bacteria cells have **flagella** or tiny whip-like structures. A bacteria may have one flagellum or many flagella. A bacteria will use its flagella to move in its environment. Bacteria that do not have flagella cannot move on their own. They rely on air or water currents, clothing, or other objects to carry them from place to place.
 * Apparatus- bacteria doesn’t contain a golgi apparatus


 * Lysosomes do not have lysomes


 * Mitochondria- do not have mitochondria


 * nuclear membrane-do not have nuclear membrane


 * nucleus-no nucleaus


 * plasmids- Baceria cells have plasmids, which are DNA cells in separate form


 * vacuoles- do not have
