ER communicates with golgi apparatus
vesicles move around by means of an extensive network or lattice of protein fibers
EUKARYOTIC CELL
microbodies and vacuole
microbodies
contain enzymes that participate in the preparatory or intermediate stages of biochemical reactions within the cell
vacuole
maintain turgor pressure
stores water, food, organic materials and enzymes
cytoskeleton
actin filament
protein fibers that play roles in cell division and shape
intermediate filament
protein fibers that provide stability of shape
microtubules
protein cylinder that moves organelle
Others
centriole
produce spindle fibre during cell division
short cylinder of microtubules
cilia
aid for movement
carry out cellular locomotion
flagella
push the cell forward
has rotating filaments that present in some bacteria
nucleus and ribosome
Ribosomes
Sites of protein synthesis
Found in all living cells
Complex molecular machines
chromatin
type of protein
diffuse threads containing DNA andptotein
nucleolus
produce subunits of ribosomes
nuclear envelope
double membrane with nuclear pore
enclosed the nucleus
nuclear pore
OUT : passage of ribosomal units out of nucleus
IN : permits passage of protein into nucleus
Energy-related organelle
chloroplast
producing sugar
carry out photosynthesis
mitochondrian
producing ATP energy
carry out cellular respiration
Endomembrane system
Golgi apparatus
processes , packages and secretes modified protein
membrane of ER
rough endoplasmic reticulum
studded with ribosomes
synthesize protein
smooth endoplasmic reticulum
synthesize lipid molecules
lacks of ribosome
vesicle
small membrane bound-sac that stores and transport subtances
transport vesicle
secretory vesicle
