Flashcards in Cell review Deck (30):
1

Prokaryote cells include

bacteria and archaea

2

what do prokaryotes lack that eukaryotes have

a membrane bound nucleus

3

the prokaryotic cell wall is primarily composed of

peptidoglycan

4

biological membranes are

thin, flexible, and stable sheet-like structures that have selective permeability

5

the phospholipid bilayer has these proteins

integral and peripheral

6

centrally located and contains the circular chromosome

nucleoid

7

large granules that contain organic or inorganic compounds

inclusion bodies

8

three things about plasmids

replicate independently of chromosomes
carry genes that benefit the bacterium
are used in molecular cloning

9

for attachment and conjugation

pili

10

are used for locomotion in prokaryotes

flagella

11

eukaryotic cells have

membrane bound organelles that increase surface area for chemical reactions

12

isolates the cell and is selectively permeable

plasma membrane

13

outside the plasma membrane are the

glycocalyx and extracellular matrix

14

a series of membranous tubules, vesicles, and flattened sacks that function for protein synthesis, folding, and glycsylation

rough endoplasmic reticulum

15

RNA/protein complexes involved in protein biosynthesis with two functional subunits

ribosomes

16

formed of large flattened sac-like membranous vesicles that processes, packages, and distributes cell products

golgi apparatus

17

contains the DNA and is the site of transcription

nucleus

18

surrounds the nucleoplam

nuclear envelope

19

nuclear envelope contains these through which most of the molecules that enter and leave the nucleus

nuclear pores

20

vesicles that contain digestive enzymes (acid hydrolases) and degrades debris involved in autophagy

lysosomes

21

four characteristics of mitochondria

are site of aerobic metabolism
principle source of cellular ATP
have inner and outer membrane surrounding matrix
contain their own DNA ad ribosomes

22

small organelle containing oxidative enzymes for detoxifies peroxides

peroxisomes

23

organelles found only in plants, algae, and some protists

plastids

24

two types of plastids

leucoplasts and chromoplasts

25

specialized chromoplasts in photosynthesis

chloroplasts

26

an intricate supportive network of fibers, filaments, and associated proteins

cytoskeleton

27

three main components of cytoskeleton

microtubules
microfilaments
intermediate filaments

28

microtubules contain

tubulin and proteins -kinesin and dynein

29

microfilaments contain

actin and proteins- myosin, troponin, tropomodulin, actinin

30

examples of intermediate filaments

keratin and cytokeratin
