Flashcards in 2.2 Prokaryotic Cells Deck (28):
1

What does the cell wall do?

protect and maintain the shape of the cell

2

What protects and maintains the shape of the cell?

cell wall

3

What is the cell wall composed of?

peptidoglycan

4

Where is the plasma membrane?

inside cell wall

5

What does the plasma membrane do?

controls movement of substances in and out of cell

6

What controls movement of substances in and out of cell?

plasma membrane

7

What is the pili?

hair-like growths on outside of cell wall

8

What are the hair-like growths on outside of cell wall?

pili

9

What are the pili used for?

Used for attachment, mainly to other cells to prepare for transfer of DNA (sexual reproduction)

10

What is used for attachment, mainly to other cells to prepare for transfer of DNA (sexual reproduction)?

pili

11

What is flagella used for?

motility

12

What is used exclusively for motolity?

flagella

13

Is flagella present in all bacterial cells?

No

14

What occurs in cytoplasm?

all cell functions because there is no compartamentalization

15

What are ribosomes the site of?

protein synthesis

16

Where is the site of protein synthesis?

ribosomes

17

What is the nucleoid region?

Area of the cell containing free floating, continuous, circular DNA thread

18

Where is the area of the cell containing free floating, continuous, circular DNA thread ?

nucleoid region

19

How do prokaryote cells divide?

binary fission

20

What happens during binary fission?

DNA is copied, two daughter chromosomes attach to different parts of plasma membrane, then the cell divides. Division occurs through cell elongation and a protein called FtsZ that partitions new DNA

21

What is number 1?

plasma membrane

22

What is number 2?

DNA (nucleoid)

23

What is number 3?

capsule

24

What is number 4?

cell wall

25

What is number 5?

mesosome

26

What is number 6?

ribosomes

27

What is number 7?

cytoplasm

28

What is number 8?

bacterial flagellum
