Question

how do the following bacteria move about?
a) cocci
b) bacilli
c) spirilla

1. a term that means “moving about” is while the term refers to self - movement.
2. match each term with its correct definition.
3. germs\ta) poisonous substances produced by some microorganisms
4. microorganism\tb) transmission of body fluids or blood through contact with an intermediate contaminated object
5. parasite\tc) one - celled microorganisms having both plant and animal characteristics. some are harmful and some are harmless
6. bacteria\td) organism of microscopic or submicroscopic size
7. virus\te) invasion of body tissues by disease - causing pathogens
8. infection\tf) transmission of blood or body fluids through touching, kissing, coughing, sneezing, and talking
9. toxin\tg) an organism that grows, feeds, and shelters on or in another organism while contributing nothing to the survival of that organism
10. direct transmission\th) synonym for any disease - producing organism
11. indirect transmission\ti) a submicroscopic particle that infects and resides in the cells of a biological organism
12. unscramble these words and use them to complete the sentences below.

briateac sopotparlm crdoeupre cniatvie
generally consist of an outer cell wall containing a liquid called. they grow and. the life cycle of bacteria is made up of two distinct phases: the active stage and the or spore - forming stage.

1. during the active stage, bacteria:

a) change color\t c) grow and reproduce
b) die\t d) dry out

Explanation:

1. Movement of bacteria: Cocci are generally non - motile. Bacilli can move using flagella. Spirilla move by means of flagella or axial filaments.
2. Terms for movement: "Motility" means moving about and "autotrophy" is not related to self - movement in this context, "locomotion" is a more general term for movement, but "motility" is the more specific biological term here.
3. Term - definition matching:

• Germs are a synonym for any disease - producing organism (h).
• Microorganism is an organism of microscopic or submicroscopic size (d).
• Parasite is an organism that grows, feeds, and shelters on or in another organism while contributing nothing to the survival of that organism (g).
• Bacteria are one - celled microorganisms having both plant and animal characteristics. Some are harmful and some are harmless (c).
• Virus is a submicroscopic particle that infects and resides in the cells of a biological organism (i).
• Infection is the invasion of body tissues by disease - causing pathogens (e).
• Toxin are poisonous substances produced by some microorganisms (a).
• Direct transmission is the transmission of blood or body fluids through touching, kissing, coughing, sneezing, and talking (f).
• Indirect transmission is the transmission of body fluids or blood through contact with an intermediate contaminated object (b).

1. Unscrambling words: "briateac" unscrambles to "bacteria", "sopotparlm" to "protoplasm", "crdoeupre" to "reproduce", "cniatvie" to "inactive". Bacteria generally consist of an outer cell wall containing a liquid called protoplasm. They grow and reproduce. The life cycle of bacteria is made up of two distinct phases: the active stage and the inactive or spore - forming stage.
2. Active stage of bacteria: During the active stage, bacteria grow and reproduce.

Answer:

1. a) Generally non - motile

b) Can move using flagella
c) Move by means of flagella or axial filaments
