eukaryotic cells Flashcards
(24 cards)
name all the parts of the eukaryotic cell
nucleus
mitochondria
rough ER
smooth ER
golgi apparatus
lysosomes
ribosomes
microvilli
what are all the parts of the nucleus
nuclear envelope
nuclear pores
chromatin
nucleolus
what does the nuclear envelope do
controls entry and exit
what do the nuclear pores do
allow large molecules like mRNA out of nucleus
what does the chromatin do
controls cell activity
what does the nucleolus do
makes ribosomes
what does the golgi apparatis do
produces enzymes
makes lysosomes
what is the mitochondria for
respiration
3 parts of mitochondria
double membrane-in/out
cristae-attachment of enzymes
matrix-protein, lipid + trace DNA
what is the microvilli
finger like projections pf epithelial cells to increase SA for absorbtion
what do lysosomes do
digest organelles
breaks down material
gets rid of harmful enzymes
what is a ribosome
found in cytoplasm and rough ER
protein synthesis
what is the rough ER
endoplasmic reticulum
ribosomes on surface
trasportation
what does the smooth ER do
synthesises, stores and transports lipids and carbs
what is mRNA
messenger RNA for protein synthesis
what is protein synthesis
process by which cells create proteins
what is the process of protein synthesis
transcription of DNA to mRNA in the nucleus
translation of mRNA to amino acids in the cytoplasm
what is a chloroplast
site of photosynthesis
what is the stricture of a chloroplast
double membrane envelope
thylakoids
grana
what is a thylakoid
fluid filled sac that stack up to form grana
what is an amyloplast
starch grain
cell stores starch to be broken into glucose and used in resporation
what is a vaccuole
stores water, sugar and salt
what is a cell wall
made of cellulose
provides cell with support and protection
