Bacteria

Question 1

How do bacteria divide?

Answer 1

binary fission:
Needs to grow, replicate all of the genetic material, and grow a new cell wall in the middle, when complete it allows the 2 halves to pull apart. Some divide once every 20 min if they have ideal conditions.

Question 2

True or False, all bacteria are bad.

Answer 2

False

Question 3

Do bacteria have a tail?

Answer 3

Some bacteria do have a tail to move faster.

Question 4

Are viruses alive?

Answer 4

Viruses are not alive. A virus is a strand of genetic material inside a protein capsule. Viruses just zombify cells and do not meet all 7 requirements to be classified as living.

Question 5

What are some characteristics of bacteria?

Answer 5

Autotrophic, cell walls are made of peptidoglycan.

Question 6

What do conditions to bacteria need to grow and multiply?

Answer 6

Warm environment, with moisture, and food.

Question 7

What do all bacteria have in common?

Answer 7

They’re all single-celled
organisms

Question 8

How did bacteria make complex life on Earth possible?

Answer 8

By releasing oxygen
into the atmosphere

Question 9

What effect do antibiotics have on bacteria?

Answer 9

They destroy bacteria

Question 10

What is the most
common forms of bacteria?

Answer 10

cocci

Question 11

What term best describes the function of flagella
in bacteria?

Answer 11

Locomotion

Question 12

How are bacterial cells different from plant and
animal cells?

Answer 12

Bacterial cells contain
almost no cell organelles or nuclei

Question 13

What is antibiotic resistance?

Answer 13

Antibiotics are a group of drugs that can kill drugs

Question 14

What domain are bacteria in?

Answer 14

Bacteria are prokaryotic organisms that belong in their own domain called simply bacteria. Prokaryotic means that they do not have a nucleus containing genetic material and their DNA is scattered throughout their cell.

Question 15

What are Microbe?

Answer 15

tiny organisms that are found almost everywhere. (Need a microscope to see) microbes include: bacteria, viruses, fungi, and protists. Not all microbes are harmful and can be really beneficial. Good microbes are called probiotics. Immune system can fight off many bacteria.

Question 16

What are the 3 main shapes of bacteria

Answer 16

Cocci: spherical shaped, Bacilli: rod shaped, Spirilli: spiral shaped

Question 17

what are the Characteristics of bacteria

Answer 17

no nucleus, mitochondria, endoplasmic reticulum, or golgi complexes. Bacteria have a cell envelope comprise of several layers. Cell wall protects the bacteria

Question 18

what is Binary fission?

Answer 18

a bacteria grows a cell new wall down the middle and splits apart. Can divide once every 20-30 min in ideal conditions. Formula to binary fission is 2 to the power of x. Definition: Process by which prokaryotic organisms. Like bacteria divide and reproduce

Question 19

Scale

Answer 19

Kilometers(km)-Meters(m)-Millimeters(mm)-Micrometers(μm)-Nanometer(nm) Each is 1000x greater than the last.

Question 20

What is Antibiotic resistance?

Answer 20

Through mutation and natural selection, bacteria can develop the ability to be unaffected by antibiotics intended to kill them. Antibiotic bacteria (superbugs) can cause infections that are hard to treat.

Question 21

Similarities and differences between bacteria:

Answer 21

Similarities: Nucleus, mitochondria, endoplasmic reticulum and more.

Differences: Flagellum, Nucleoid, Plasmid, Cell wall, Pilus, and capsule.

Question 22

9 Bacteria organelles:

Answer 22

1. Nucleoid: Region inside the cell that contains genetic material but is not surrounded by a nuclear membrane
2. Plasmid: Circular piece of genetic material
3. Pilus: Hair like structure that attaches the cell to a surface and can transfer genetic material from one cell to another
4. Flagellum: Hair like structure that the cell uses for movement
5. Capsule: Outermost layer of the cell that provides protection
6. Cell wall: a wall made of peptidoglycan made to protect the cell
7. Cytoplasm: Everything between the nuclear membrane and the cell membrane
8. Ribosomes: Small structure that synthesizes proteins
9. Cell membrane: membrane that surrounds and protects the cell.
