Name 6 organelles listed in text
Ribosomes, Endoplasmic Reticulum, Golgi Apparatus, Mitochondria, Lysosomes, Centrioles
function of Ribosomes
PROTEIN FACTORIES. Make enzymes and other proteins
function of Endoplasmic Reticulum (ER)
CARRIES PROTEINS and other substances through cytoplasm
function of Golgi Apparatus

function of Centrioles
Play and important role in CELL REPRODUCTION
what are Cilia
Hairlike processes that project from epithelial cells
what is Flagellum
“Tail” of the sperm, enables sperm to move toward ovum
function of Nucleus
