Activity 3 Flashcards
(38 cards)
The study of biological entities too small to be seen with the naked eye.
Microbiology
The three general morphological shapes of bacteria
rod
coccus
spiral
also referred to as bacilli, can be found occasionally in pairs (diplobacilli) and in
chains (streptobacilli).
Rod-shaped bacteria
The type of rod-shaped bacteria found in pairs
Diplobacilli
The type of rod-shaped bacteria found in chains
Streptobacilli
The five patterns of spherical (coccus) bacteria
Diplococci
Streptococci
Tetrads
Staphylococci
Sarcinae
The type of spherical bacteria found in pairs
Diplococci
The type of spherical bacteria found in chains of four or more cells.
Streptococci
The type of spherical bacteria arranged in a square of four cells
Tetrads
The type of spherical bacteria, irregular groups of bacterial cells resembling grape clusters.
Staphylococci
The type of spherical bacteria forming cuboidal packets of eight cells
Sarcinae
Two groups of coiled or spiral-shaped bacteria
Spirochetes and spirilla
Consist of flexible, wavering forms with several coils
Spirochetes
rigid bacteria possessing one or several curves.
Spirilla
Spiral forms that are short and do not form complete coils are called _____.
vibrio
The five essential structural components of a bacterial cell
Nucleoid (DNA)
Ribosomes
Cell membrane
Cell wall
Surface layer
The three architectural regions of a bacterial cell
Appendages
Cell envelope
Cytoplasmic region
(attachments to the cell
surface) in the form of flagella and pili (fimbriae)
Appendages
consisting of a capsule, cell wall and plasma membrane
Cell envelope
contains the cell chromosome (DNA) and ribosomes and various sorts of inclusion.
Cytoplasmic region
The bacterial appendages responsible for movement.
Flagella
The bacterial appendages involved in attachment and conjugation.
Pili (Fimbriae)
The outermost layer of some bacteria that protects against desiccation and immune responses
Capsule
The bacterial structure responsible for providing shape and structural support.
Cell wall
