10. / an organism made out of more than one cell.
12. / simplest cell structure without compartments or a nucleus. Have naked DNA and no mitochondria. Filled with cytoplasm.
13. / the expression of a particular gene(s) and not others in order for cell specialization.
14. / division of pre-existing cells or by prokaryotic cells for asexual reproduction. Single chromosome is replicated and moves to the opposite ends of the cell and detaches to form a copy of the chromosome.

1. / undifferentiated cells that have a capacity to divide into cells of the similar type, or to specialize into different types of cells.
2. / responsible for aerobic respiration. Converts chemical energy into ATP using oxygen.
3. / the theory that cells form the fundamental structural and functional units of all living organisms
5. / a two-layered arrangement of phosphate and lipid molecules that form a cell membrane, the hydrophobic lipid ends facing inward and the hydrophilic phosphate ends facing outward.
8. / have compartments for the chromosomes, this has advantages such as the pH and other damaging substances are maintained within the membrane of an organelle.
11. / the structural adaption of a cell to suit a particular function.
