Ribosomes
Composed of RNA and protein. Actual sites of protein synthesis. Synthesize proteins for: 1. use in the cell (free ribosomes) 2. secretion, incorporation into plasma membrane, or lysosomes (fixed ribosomes)
Cytoskeleton
Composed of microfilaments, intermediate filaments and microtubules. Provides structural support; facilitates cytoplasmic streaming, organelle and cellular motility, transport of materials, and chromosomal movement in cell division.
Centrosome
Organize microtubules during cell division for movement of the chromosomes
Cilia
Move fluid, mucus and materials over the cell surface
Flagellum
Propels sperm cells in human male
Microvilli
Increase membrane surface area for increased absorption and/or secretion
