chapter 4 Flashcards
cells arise from other cells through replication
mitosis
outer lining of all cells
plasma membrane
flexible, chemically active outer lining of cell
plasma membrane
comprised of phospholipids with interspersed molecules
plasma membrane
DNA
chromosomes
protein production
ribosomes
area inside the cell
cytoplasm
do prokaryotes have a nucleus?
NO
where does DNA coil in a prokaryote
nucleoid
prokaryotes ribosomes vs eukaryotes
smaller more basic
provides protection for prokaryotic cells
cell wall
sticky outer coat
capsule
movement and attachment of prokaryotic cells
cell projections
make up every complex living thing
eukaryotic cells
main parts of a eukaryotic cell
genetic control
organelles of metabolism
organelles of energy processing
cytoskeleton
nucleus and ribosomes in eukaryotic cells
genetic control
rough and smooth endoplasmic reticulum (ER), golgi complex, lysosome, vaculoes and peroxisomes
organelles of metabolism
parts of organelles of metabolism
RER and SER Golgi complex Lysosome Vaculoes Peroxisomes
mitochondria and cholorplasts
organelles of energy processing
internal support system of a eukaryotic cell
cytoskeleton
what do both plant cells and animal cells contain?
Nucleus, ribosomes, mitochondria, SER, RER, cytosol, and plasma membrane
plants do NOT have
lysosomes or centrioles
plant cells DO have
central vaculoe
thick cell walls
choloroplasts
holds all information (DNA)
nucleus
DNA wound around proteins
chromatin
the nuclear envelope wraps around….
phospholipid bilayer
seperates nucleus from cytosol
nuclear envelope
holes in nuclear envelope
nuclear pores
allow RNA and other information to pass
nuclear pores
located in nucleus
nucleolus
produces ribosomal RNA (rRNA)/ make up ribosomes
nucleolus
protein synthesis using “code” from DNA
ribosomes
made up of RNA
ribosomes
where are ribosomes located?
free or attached to RER
using mRNA to code for proteins
translation
protein synthesis
translation
what does translation
ribosomes
make a chain to form polypeptide chains
amino acids
what do ribosomes match the mRNA code to
codons (for amino acids that build proteins)
processes materials
endomembrane system
what in the endomembrane system transfers materials
vesicles (bubble taxis)
what makes up the endomembrane system
ER Golgi Lysosomes Vaculoes Plasma Membrane
what do transport vesicles do with finished proteins
move from RER to Golgi complex
aids with translation
RER
why is it rough RER
embedded with ribosomes
process short piece of mRNA
RER
make more membrane
REr
where do ribosomes drop polypeptide chains
into internal spaces of RER
fold chains becoming proteins
RER
synthesize lipids and detoxify harmful substances
SER
store calcium for muscle and nervous functions
SER
does NOT participate in protein synthesis
SER
Responsible for making steroids
SER
process and distribute proteins
Golgi complex
add chemical tags like phosphate
golgi complex
where do proteins go after golgi
PM
recylcing and garbage center of cell
lysosome
digests food in protists
lysosome
digests warn out cell parts and foreign particles
lysosome
filled with acids and enzymes to break particles down
lysosome
do animals have a central vaculoe
NO PLANTS ONLY
similar to animals lysosome
central vaculoe
stores nutrients and degrades wastes with specialized digestive enzymes
central vaculoe
help SER and lysosomes
peroxisomes
why do peroxisomes produce hydrogen peroxide
to convert toxins to water
turns glucose into a form of energy our bodies can use
Mitochondria
contains inner and outer membranes for increased surface area
mitochondria
use glucose and oxygen to make ATP, H2O and CO2
mitochondria
thick fluid in chloroplast
stroma
network of sacs in cholorplast
thylakoid
network of protein
filaments
cell structure, cell movement, and transport of materials in cell
cytoskeleton
webs of internal proteins that hold structure, transport materials and allow for cell movement
cytoskeleton
pieces are both stationary and moving
cytoskeleton
three types of cytoskeleton
microfilaments
intermidiate filaments
microtubules
what are microfilaments made of
actin
what is actin
protein
filament that is structure and cell movement
microfilaments
most permanent filament
intermediate
stabilize nucleus and organelles
intermediate
made of tubulin
microtubules
act as main support and monorails to transport vesicles
microtubules
types of microfilaments
cilia
flagella
extended from cells in great numbers
cilia
move cell or move material around the cell
cilia
long-tail like extensions
flagella
movement of the cell
flagella
found in animal cells to support layers
extracellular matrix
anchoring junctions
desmosomes
membrane bound organelles
mitochondria SER RER vaculoes vessicles Golgi nucleus cholorplasts lysosomes
