cell parts Flashcards
nucleus
controls center of cell
ribosomes
protein synthesis
rough er
package proteins for secretion (ribosomes on surface)
smooth er
synthesize lipids, metabolize carbs, detox drugs and poisons (no ribosomes on surface)
golgi apparatus
PMS proteins and lipid molecules
cis face
receives vesicles
trans face
ships vesicles
lysosomes
recycle cells materials
vacuoles
store materials
mitochondria
site of cellular respiration
chloroplasts
site of photosynthesis
peroxisomes
breaks down fatty acids
cytoskeleton
support and regulate biochemical activities
centrosomes
region where microtubules grow
cilia
move fluids (short and numerous)
flagella
propel through water (long and few)
ex. sperm
cell wall
protect plant and maintain shape
plasmodesmata
allows passage of molecules from cell to cell
extracellular matrix (ecm)
strengthens tissues and transmits external signals to cell
tight junctions
2 cells form watertight seal
desmosomes
fasten cells into strong sheets
gap junctions
channels for ions, sugar, small molecules can pass
