1. Active Transport transport that requires a cell to expend its own energy to pump a molecule across the membrane. Movement of molecules from areas of low concentration to areas of high transportation

2. Endocytosis transport that occurs when the cell membrane encloses around the particle forming a pouch, the pouch is then draw into the cell, requires energy on behalf of the cell

3. Exocytosis transport that occurs when the cell memberane forms an internal pouch of large/multiple molecules and then releases them outside of the cell, requires energy on behalf of the cell

4. Facilitated Diffusion the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins

5. Hypertonic Solution a situation that describes a solution when the concentration of solutes in solution is higher than inside the cell a term to describe a cell or solution that GAINS water

6. Isotonic Solution an adjective that describes a solution when the concentration of solutes in solution is the same as inside the cell a term to describe when a cell is equal to its surrounding solution regarding water concentration

7. Osmosis the diffusion of water (from a high conc. To a low conc.) across a cell membrane (selectively permeable membrane)

8. Hypotonic Solution a situation that describes a solution when the concentration of solutes in solution is lower than inside the cell a term to describe a cell or solution that LOSES water

9. Passive Transport transport that does not require the cell's chemical energy to move molecules across the membrane

10. Anaphase Third phase of mitosis in which sister chromatids are pulled to opposite sides of the cell

11. Solute substance that dissolves in the solvent Ex:salt, Kool aid

12. Solution a homogeneous mixture of solute(s) and solvent(s)

13. Cell Cycle The stages that take place between the time a eukaryotic cell divides and the time the daughter cells divide. (stages of growth, preparation, and division (Interphase and Mitosis)

14. Mitosis 1 diploid parent cell splits into 2 identical diploid daughter cells.

15. Prophase Nucleolus has disappeared, and duplicated chromosomes are visible. Centrosomes begin moving apart, and spindle is in process of forming.

16. Metaphase Second phase of mitosis, during which the chromosomes line up across the center of the cell

17. Telophase The fourth and final stage of mitosis, in which nuclei are forming and cytokinesis has typically begun.

18. Chromosomes DNA that is coiled together and condensed into small packages (like DNA suitcases)

19. Homeostasis the ability of an organism to self-adjust to maintain a balance of life functions in a changing environment

20. Diffusion the process by which molecules of a substance move from an area of high concentration of that substance to areas of lower concentration until they are evenly distributed about the container

21. Karyotype Is the number and appearance of chromosomes in the nucleus of a eukaryotic cell. The term is also used for the complete set of chromosomes in a species, or an individual organism
