u got more than the usual cytoplasm to regulate
|
|
largest organelle
|
nucleus
|
|
shape of nucleus conforms to
|
the shape of the cell
|
|
what is continuous with the nuclear membrane

the rough ER
|
|
does the nuclues have a double membrane
|
yes
|

nuclear pore has proteins surrounding it
|
|
whats analogous to the cytoplasm in the nucleus
|
the nucleoplasm
|
|
what can u find in the nucleoplasm
|
dissolved salts, nutrients, solutes
|

what is extended chromatin
|
chromatin with DNA replication action, when cell is not dividing
|
|
short condensed coils of dna that form to prepare for division
|
chromosomes
|
|
the cells muscles, bones, and ligaments
|
the cytoskeleton
|
|
three type of rods in the cytoskeleton

microtubules
|
|
the protein that makes microtubules

tubulin
|
|
most microtubules radiate from the
|
centrosome

from the three rods, which one are the organelles hanging onto
|
microtubules
|
|
what are the molecules that move organelles around from the microtubules
|
motor proteins

|
Microtubules are constantly moving and growing from the centrosome
|
True
|
|
the thinnest of the rods
|
microfilaments
|
|
microfilaments are made of
|
actin
|
|
these tubes are involved in cell motility or changes in its shape

|
these tubes are involved in muscle movement
|
microfilaments
|
|
these rods are involved in amoeba motion
|
microfilaments
|
|
these tubes pinch the cell in two during cell division, form the (cleavage furrow)
|
microfilaments
|
|
the most stable and permanment of the tubes
|
intermediate filaments
|
|
purpose of intermediate filaments
|
resist pulling forces exerted on the cell
|
|
the name of the microtuble organizing center

centrosome
|
|
a centrosome is composed of
|
centrioles
|
|
whats the role of the centrosome
|
organize microtubules, and organize the mitotic spindle
|
|
what does a centriole look like
|
nine microtubules arranged to form a tube
|
|
enable organelles to walk along microtubues
|
motor protein
|
|
cilia are good for moving in what kind of direction
|
in one direction
|
|
a cilia is basically
|
a microtubles organized in a series of tubes out of the cytoplasm
|
|
a flagella is basically
|
a microtuble microtubles organized in a series of tubes out of the cytoplasm but longer a cilia

what are basal bodies
|
centrioles form the basis for flagella and cilia
