Sr. # Questions Answers Choice
1 With the help of flagella, bacteria can detect and move in response to chemical signals which is a behaviour called: chemotherapeutic chemosynthetic chemotaxis both a & b
2 Primary function of flagella is to help in: walking motility running rest
3 When flagella surround the whole bacteria cell,the condition is called: Peritrichous atrichous lophotrichous amphreichous
4 When tuft of flagella at each of two poles is present in bacteria, the condition is called: peritrichous atrichous lophotrichous amphtrichous
5 The condition in which bacteria have a single polar flagellum is called: monotrichous atrichous lophotrichous amphtrichous
6 The condition in which Bacteria are without any flagella is called: monotrichous atrichous lophotrichous amphtrichous
7 A chain of bacilli is called: Streptobacillus diplobacillus staohylobacillus tetrad
8 Spirals come in the form: Vibrio Spirillum spirochete all a,b,c
9 The spiral shaped bacteria are: helically coiled curly colied cochlearly colied spirally colied
10 Staphylococci aureus,Diplicocci pneumoniae etc.,are examples of: bacilli spiral cocci none
11 In staphylococus arrangement cocci are arranged in irregular,often: banana-like clusters grape-like clusters berry-like clusters cherry-like clusters
12 When division occurred in random planes it will produce a: staphylococcus arrangement  diplococcus arrangement  streptococcus arrangement  bacillococcus arrangement 
13 When the division is in three planes it will produce a: sarcina arrangement  bivalent arrangement  tetrad arrangement  helical arrangement 
14 A tetrad is a square of: 2 cocci 4 cocci 6 cocci 8 cocci
15 When the division of cell is in two planes it will produce a: sarcina arrangement bivalent arrangement  tetrad arrangement  helical arrangement 
16 When cocci form long chain of cells then arrangement is called as: tetrad diplococcus sarcina streptococci
17 When cocci occur in pairs then arrangement is: teyrad diplococcus sarcina streptococci
18 The general shapes of bacteria are known as: cocci,bacilli and spiral cocci,bacilli and vibrio cocci,comma and spiral cubical,bacilli and spiral 
19 On the basis of general shape,bacteria are classified into: two categories three categories four categories five categories
20 The smallest bacteria are approximately the size of the largest viruses i.e., Paramyxoviruses adenoviruses parvoviruses poxviruses
