Anatomy Ch 3 Organelles

Front 1

if cells have more than one nucleus its cuz

Back 1

u got more than the usual cytoplasm to regulate

Front 2

largest organelle

Back 2

nucleus

Front 3

shape of nucleus conforms to

Back 3

the shape of the cell

Front 4

what is continuous with the nuclear membrane

Back 4

the rough ER

Front 5

does the nuclues have a double membrane

Back 5

yes

Front 6

what controls what goes in and out of the nucleus

Back 6

nuclear pore has proteins surrounding it

Front 7

whats analogous to the cytoplasm in the nucleus

Back 7

the nucleoplasm

Front 8

what can u find in the nucleoplasm

Back 8

dissolved salts, nutrients, solutes

Front 9

are the nucleoli membrane bounded

Back 9

no

Front 10

how many nucleoli per cell and what do they do

Back 10

one or two make proteins

Front 11

DNA plus protein equals

Back 11

nucleosomes

Front 12

fundamental unit of chromatin

Back 12

nucleosomes

Front 13

what is extended chromatin

Back 13

chromatin with DNA replication action, when cell is not dividing

Front 14

short condensed coils of dna that form to prepare for division

Back 14

chromosomes

Front 15

the cells muscles, bones, and ligaments

Back 15

the cytoskeleton

Front 16

three type of rods in the cytoskeleton

Back 16

microtubules, microfilamnets, and intermediate filaments

Front 17

are the three types of rods in the skeleton membrane covered

Back 17

no

Front 18

the rods with the largest diameter

Back 18

microtubules

Front 19

the protein that makes microtubules

Back 19

tubulin

Front 20

most microtubules radiate from the

Back 20

centrosome

Front 21

from the three rods, which one determines overall shape

Back 21

microtubules

Front 22

from the three rods, which one are the organelles hanging onto

Back 22

microtubules

Front 23

what are the molecules that move organelles around from the microtubules

Back 23

motor proteins

Front 24

Microtubules are constantly moving and growing from the centrosome

Back 24

True

Front 25

the thinnest of the rods

Back 25

microfilaments

Front 26

microfilaments are made of

Back 26

actin

Front 27

these tubes are involved in cell motility or changes in its shape

Back 27

microfilaments

Front 28

these tubes are involved in muscle movement

Back 28

microfilaments

Front 29

these rods are involved in amoeba motion

Back 29

microfilaments

Front 30

these tubes pinch the cell in two during cell division, form the (cleavage furrow)

Back 30

microfilaments

Front 31

the most stable and permanment of the tubes

Back 31

intermediate filaments

Front 32

purpose of intermediate filaments

Back 32

resist pulling forces exerted on the cell

Front 33

the name of the microtuble organizing center

Back 33

centrosome

Front 34

a centrosome is composed of

Back 34

centrioles

Front 35

whats the role of the centrosome

Back 35

organize microtubules, and organize the mitotic spindle

Front 36

what does a centriole look like

Back 36

nine microtubules arranged to form a tube

Front 37

enable organelles to walk along microtubues

Back 37

motor protein

Front 38

cilia are good for moving in what kind of direction

Back 38

in one direction

Front 39

a cilia is basically

Back 39

a microtubles organized in a series of tubes out of the cytoplasm

Front 40

a flagella is basically

Back 40

a microtuble microtubles organized in a series of tubes out of the cytoplasm but longer a cilia

Front 41

what are basal bodies

Back 41

centrioles form the basis for flagella and cilia

Front 42

centrioles and basal bodies are identical

Back 42

T

Front 43

protein that moves cilia

Back 43
