2. a system of membranes that is found in a cells cytoplasm and that assists in theh production, processing and transport of proteins and in the production of lipids
6. cell organelle composed of RNA and protein; the site of protein synthesis
9. in a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism and production
10. cell organelle that helps make and package materials to be transported out of the cell
11. in biology, the smallest unit that can perform all life processes; it is covered by a membrane and have DNA and cytoplasm
12. a small cavity or sac that contains materials in a eukoryotic cell

1. an organism that consists of a single cell that does not have a nucleus
2. an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi, but not archaea or bacteria
3. a cell organelle that contains digestive enzymes
4. in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
5. a phospholipid layer that covers a cell's surface; acts as a barrier between the inside of a cell and the cell's environment
7. one of the small bodies in a cells cytoplasm that are specialized to perform a specific function
8. a rigid structure that surrounds the cell membrane and provides support to the cell
