100% Solved
Bacteria and Archaea lack Endoplasmic reticulum and Golgi apparatus
Bacteria and Archaea Lack Lysosomes and Chloroplasts
Bacteria and Archaea lack membrane-bound organelles such as mitochondria,
endoplasmic reticulum, Golgi apparatus
Bacteria and Archaea lack Histones and Cytoskeleton
Spherical cell shape coccus
Rod-shape cell bacillus or coccobacillus
Curves shape cell vibrio, spirillum and spirochete
,Diplo cell arrangement Cells in pairs. ex. Diplococcus, Diplobacillus
Tetrad cell arrangement Grouping of four cells arranged in a square
Strepto cell arrangement Cells in chains. Ex. Streptococcus, streptobacillus
Staphylo cell arrangement Cells in grape like clusters. Ex. Staphylococcus.
Palisades cell arrangement Elongated cells are aligned closely together in a vertical
orientation, resembling a row of standing soldiers
Archaea Prokaryotic, single celled organisms of primitive origin that have unusual
anatomy physiology and genetics and live in harsh habitats
Fermentation The extraction of energy through anaerobic degradation of substrates into
simpler reduced metabolites
Appendages Accessory structures that sprout from the surface of bacteria
, Function of bacterial flagella A appendage for movement through its environment
Polar monotrichous flagella single flagellum at one pole
Lophotrichous flagella a tuft or bunch of flagella coming from one pole
Amphitrichous flagella flagella at both poles of the cell
Peritrichous flagella Spread over entire surface of cell randomly
Chemotaxis The tendency of organisms to move in response to chemical gradient (toward
an attractant or to avoid adverse stimuli)
What group of bacteria have Periplasmic flagella Corkscrew shape of bacteria called
spirochetes
