Moneran

moneran - Are organisms that typically reproduce by asexual budding or fission and whose nutritional mode is absorption or photosynthesis or chemosynthesis

microorganism - any organism of microscopic size
kingdom Monera, Monera - prokaryotic bacteria and blue-green algae and various primitive pathogens; because of lack of consensus on how to divide the organisms into phyla informal names are used for the major divisions
archaebacteria, archaebacterium, archaeobacteria, archeobacteria - considered ancient life forms that evolved separately from bacteria and blue-green algae
eubacteria, eubacterium, true bacteria - a large group of bacteria having rigid cell walls; motile types have flagella

 

What is a prokaryotic cell?  A prokaryotic cell is a cell with no membrane-bounded nucleus.

What kingdom are the monera in?  Prokaryotic organisms belong to the Monera Kingdom.

Organisms in the Monera Kingdom include bacteria and archaea domains.  Bacteria in these domains include Glococapsa, Oscillatoria, Anaboena, Staphylorcci, and Streptococci.
 

Functions of the following parts of the bacteria.
            a.    nucleoid  - reproduction    

b.    pili  - used to attach bacterium to another cell  

c.    cell wall – encloses the plasma

d.    capsule – a polysaccharide or protein coating that some disease-causing bacteria secrete outside their cell wall

         e.    cell membrane    holds and regulates cell contents and communicates with other cells.

f.    flagella – hair-like extension used to propel some cells through fluids

g.   cytoplasm – material inside of a cell – hold the cell contents

    

What is the purpose of the gram stain?   The gram stain is used to distinguish cell wall construction.  How does it work? Stains thick peplidoglycan blue (gram positive).  Stains thin peplidoglycan red (gram negative).
 
Shapes of bacteria.
            Rod - Bacillus
            Round – Coccu

            Spiral – Spirillum

Modes of nutrition found in prokaryotic cells.

             a.     saprophytic – Send out digestive enzymes into the environment and then take up the resulting nutrient molecules.
 

            b.    chemosynthetic – Capable of oxidizing inorganic molecules to obtain energy.
 

c.    photosynthetic – A series of chemical reactions in which light energy is used to synthesize organic molecules.  Usually carbon dioxide and water is synthesized into carbohydrates.
 

            d.    parasitic – Lives in or on a host and weakens it.
 

Characteristics of cyanobacteria.  Cyanobacteria are photosynthetic prokaryotic cells that utilize chlorophyll and release oxygen as a photocynthetic byproduct (sometimes called blue-green algae).

What procedure was used to perform this task? Gram stain as described above.
