if cells have more than one nucleus its cuz
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
what controls what goes in and out of the nucleus
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
are the nucleoli membrane bounded
no
how many nucleoli per cell and what do they do
one or two make proteins
DNA plus protein equals
nucleosomes
fundamental unit of chromatin
nucleosomes
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, microfilamnets, and intermediate filaments
are the three types of rods in the skeleton membrane covered
no
the rods with the largest diameter
microtubules
the protein that makes microtubules
tubulin
most microtubules radiate from the
centrosome
from the three rods, which one determines overall shape
microtubules
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
microfilaments
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
centrioles and basal bodies are identical
T
protein that moves cilia
dyenin
