cell organelles Flashcards
cell membrane
membrane= phospholipid bilayer= plasma membrane
selectively permeable
cytoplasm
also, cytosol
jelly fluid fills the cell
nucleus
contains genetic material
has pores that always large molecules like RNA to get in
nucleolus
inside nucleus
ribosome synthesis
Rough endo
protein synthesis because studded with ribosomes
Transport through cytoplasm
smooth endo
Hormone, lipid, cholesterol synthesis
Carbohydrates metabolism
Detoxifies cell
Connects RER to golgi
vesicle
tiny vacuoles to transport substances in and out of cell
golgi apparatus
modify
store
packages
substances produced in RER
mitochondria
power house of cell
site of cellular respiration
has own DNA
cytoskeleton
protein filaments that give the cell its structure and ability movement
cytoskeleton made of
microtubules:
in cilia, flagella, spindle fibres
microfilaments:
skeletal muscle contraction
amoeba movement
lysosome
in animals only
intracellular digestion
apoptosis (hydrolysis, hydration)
centrosome
2 centrioles
in anaphase used
cell wall
cell shape and protection
bacteria: peptidoglycan
fungi: chitin
plants: cellulose
flagella
movement/propulsion
long
cilia
many and short
movement
paramecium
vacoule
stores toxins water food
in PLANTS ONLY
plastids
PLANTS ONLY
chloroplast:
chlorophyll (green)
photosynthesis
own DNA
chromoplast:
carotenoids pigments
leukoplast:
roots
stores starch
no color
