7. a eukaryotic cell that contains a true nucleus and certain organelles to perform specific functions
8. a type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles
11. an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times
13. an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria

9. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
10. the smallest structural and functional unit of an organism
12. a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose
