2. composition of a solution outside of a cell and its ability to alter the internal water volume of a cell
3. fluid portion of the cytoplasm
7. division of the cytoplasm during the cell cycle
9. movement of molecules through a membrane as a result of hydrostatic pressure
10. division of a somatic cell forming two genetically identical somatic cells
11. movement of water through a selectively permeable membrane toward a greater concentration of impermeant solute
12. the complex of DNA and protein making up the cell's 46 chromosomes
15. selectively permeable outer boundary of a cell consisting of a phospholipid bilayer
16. system of protein tubules and filaments that reinforce a cell's 3-D form
17. programmed cell death

1. organelle that prepares and modifies cellular products for secretion
3. threadlike structure built of DNA and protein that condenses and becomes visible in a cell's nucleus during mitosis
4. random movement of molecules from a region of higher concentration to lower concentration
5. process by which a cell membrane envelopes a particle and draws it into the cell in a vesicle
6. organelle housing enzymes that catalyze aerobic reactions of cellular respiration
8. organelle composed of RNA and protein that provides structural support and enzymatic activity for protein synthesis
13. small organ; any of the structures in cells that has a specialized function
14. life cycle of a cell consisting of interphase, mitosis, and cytokinesis
