An organelle is

• a specialized structure that performs important cellular functions within a eukaryotic cell

• an internal membrane system found in eukaryotic cells; place where lipid components of the cell are assembled.

• strong, supporting layer around the cell membrane in some cells

• in cells, structure that contains the cell's genetic material in the form of DNA

a cell organelle composed of RNA and protein throughout the cytoplasm; the site of protein synthesis is

• mitochondria

• vacuole

• ribosome

• lysosomes

the process by which particles tend to move from an area where they are more concentrated to an area of less concentration

• diffusion

• osmosis
