6. 1.What are the two parts of a solution? 2.What percentage must those two parts always add up to? 3.What is a concentration gradient? 4.What is a solution called when it has more solutes and more pull on the water than another solution? 5.What is the diffusion of water called? 6.Diffusion always moves from a _____________ concentration to a ____________ concentration. 7.What is it called when there is no net movement of water molecules across the membrane? 8.What is a solution that has less solutes and less pull on water than another solution called? 9.What is a solution that has equal solutes and equal pull on water compared to another solution called?

7. Nucleus Cell Membrane Cell Membrane Nucleolus Cytoplasm Cell Wall Cell Wall Cytoskeleton

8. Rough Endoplasmic Reticulum Rough Endoplasmic Reticulum Golgi apparatus Mitochondria Ribosomes Smooth Endoplasmic Reticulum Smooth Endoplasmic Reticulum Chloroplasts

9. Small Vacuoles Small Vacuoles Lysosomes Vesicles Centrosome Large Central Vacuole Centrioles

10. Double membrane organelle that contains the cell’s DNA and directs cell function Barrier that regulates what goes in and out of the cell Dense area of RNA that makes ribosomes Jelly-like matrix between nucleus and cell membrane that holds organelles and dissolved substances Rigid structure found in plants and bacteria that helps protect and give structure to the cell Protein microtubules that help shape the cell and move substances within the cell

11. Membrane channels studded with ribosomes “UPS” of the cell; processes and packages proteins and makes lysosomes Organelle where cellular respiration takes place converting products of glucose into ATP for cell energy Site of protein synthesis Lacks ribosomes on surface of membrane channels; involved in lipid synthesis Green organelle found in plants that is site of photosynthesis

12. Small membrane bubbles that contain food particles Vacuole full of digestive enzymes Small membrane bubbles that break off cell organelles to transport proteins within cell Area in cytoplasm where microtubules are formed Large vacuole in center of plant cells that stores water Microtubules found in animal cells involved in cell division

15. Small Vacuoles Small Vacuoles Lysosomes Vesicles Centrosome Large Central Vacuole Centrioles

16. Membrane-bound organelles Absent Nucleus Present Membrane-bound organelles Present Can be single-cell microscopic or multicellular and macroscopic Nucleus Absent Can only be single-cell and microscopic

17. Facilitated diffusion Diffusion Moves from High to Low concentrations Moves from Low to High concentrations Osmosis Uses Cell Energy

18. Exocytosis Does NOT require cell energy Protein Pump Moves with concentration gradient Endocytosis Requires ATP

19. Very Large molecules Small nonpolar molecules Ions and polar molecules Passes through phospholipid layer Moves against concentration gradient Always open protein channel

20. Exocytosis Diffusion Facilitated Diffusion Active Transport Osmosis Endocytosis (Term)

21. Movement of Large molecules out of the cell by vesicles fusing with cell membrane Movement of molecules from an area of high concentration to an area of low concentration Diffusion through always open protein channels Movement against the concentration gradient by use of protein pumps and cell ATP Diffusion of water Movement of large molecules into the cell by forming a vacuole out of the cell membrane (Definition)
