Central Vacuole N. Unicellular O. Multicellular P. Centrioles Q. Chloroplast R. Prokaryotic 1. small, spherical, membrane bound sac that encloses cellular materials for transport within the cell, or for export. 2. site of protein synthesis; this structure is common to all cells 3. fluid, and all cellular contents outside the nucleus; site of many metabolic reactions. 4. loose, thread-like form of DNA bound to histone proteins. 5. rigid, protective layer outside the cell membrane in plant cells and prokaryotes. 6. large fluid-filled organelle that helps support plant cell structure. 7. a dense DNA region in the nucleus where ribosome production begins. 8. 9. an organism with different cell types specialized for different functions; results in multiple levels of cellular organization network of tubules and filaments that support cellular structure and movement. 10. converts energy in organic compounds like glucose into usable cellular energy (ATP). 11. uses light energy to make carbohydrates from carbon dioxide and water. 12. internal membrane system that lacks ribosomes, aids in the production of lipids 13. any organism made up of only a single cell. 14. 15. modifies new proteins and lipids, directs them to various places in the cell or prepares them for export. 16. folded membrane system found near the nucleus that has ribosomes attached. 17. organelle made of tubules that helps organize cell division in animal cells. 18 made up of a lipid bilayer, this structure encloses the cell and monitors what enters and exits. unicellular organism that lacks a nucleus and membrane-bound organelles..
