Flashcards in B1.1.2 Bacterial cells Deck (20):
1

Are Bacteria an unicellular organism or an multicellular organism?

Unicellular

2

What organisms are the smallest living organisms?

Bacteria

3

What are the seven life processes which every cell can carry out?

Movement, reproduction, sensitivity, growth, respiration, excretion and nutririon

4

Give an example of an Prokaryotic bacterial cell.

Escherichia coil (E. coil)
Streptococcus bacteria
Streptomyces bacteria

5

What does Escherichia coil (E. coil) cause?

Food poisoning

6

what does Streptococcus bacteria cause?

Sore throats

7

Where is Streptomyces bacteria found?

In the soil

8

Which subcellular structures do prokaryotic cells contain?

A cell wall, Genetic material, cell memrane, cytoplasm

9

B1.1.1 explains the functions of the subcellular structures in prokaryotic cells.

Okay i will look because i am a good scientific pinapple :)

10

What are the extra subcellular structures that some types of bacterial cells contain?

Flagella, pili, slime capsule, plasmid

11

What is the singular for flagella?

Flagellum

12

What is the function of flagella?

To allow the cell to move through liquids

13

Flagella has a '____-____' structure

Tail-like

14

Pili are tiny '____-___' structures

Hair-like

15

What are the two functions of the pili?

It enables the cell to attach to structures (such as the cells that line your digestive tract). And also used to transfer genetic material between bacteria

16

Is the slime capsule outside or inside the cell wall?

Outside

17

What are the two functions of the slime capsule?

It protects the bacterium from dying out and from poisonous substances. And it also helps the bacterium to stick to smooth surfaces

18

What is the plasmid?

A circular piece of DNA

19

What is the function of the plasmid?

It is used to store extra genes

20

What are the extra genes stored in the plasmid for?

To help the bacterium in times of stress, for example this is where the antibiotic resistance genes are normally found
