2. Parts of the Eukaryotic Cell

3. Cell Membrane

4. Selectively Permeable = only certain things can enter / exit the cell

5. Made primarily of lipids and proteins

6. Integral proteins form channels or pores which certain substances can pass

7. Fluid mosaic model = cell membrane acts more like a fluid than a solid (flexible); made up of a variety of parts

8. Cell Membrane

9. Cytoplasm Contains the organelles of the cell

10. Contains cytosol = a gelatin-like aqueous fluid which organelles are in

11. Cytoplasm

12. Nucleus Stores the hereditary information in its DNA; controls the cell

13. Nucleus

14. Nuclear Membrane Double membrane that surrounds the nucleus, has nuclear pores

15. Nuclear Pores

16. Nucleolus Site where ribosomes are made

17. Nucleus/Nuclear Membrane/Nucleolus

18. Ribosomes Most numerous organelle; synthesize proteins

20. Mitochondria Sites of chemical reactions – supply energy to cell

21. More numerous in cells with high energy requirements

22. Cristae= folds that increase surface area (more sites for chemical reactions)

23. Mitochondria

24. Endoplasmic Reticulum (ER) A system of membranous tubules and sacs

25. Functions as a highway along which molecules move from one part of the cell to another

26. Two types: 1) Rough ER (has ribosomes) 2) Smooth ER (no ribosomes)

27. Rough ER

28. Smooth ER

29. Rough and Smooth ER

30. Golgi Apparatus The processing, packaging, and secreting organelle of the cell

31. Golgi Apparatus

32. Lysosomes Organelles that contain enzymes that digest stuff

33. Common in cells of animals, fungi, and protists, but rare in plant cells

34. Lysosomes

35. Microtubules Contributes to the support, movement, and division of the cell

36. Microtubules

37. Flagella Whipping action propels cells and makes them move

38. Flagella

39. Cell Wall Rigidity helps support and protect the plant cell

40. Cell Wall

41. Plant Cells with Cell Wall

42. Vacuole Fluid filled organelle that stores enzymes, metabolic wastes, and water

43. Vacuole

44. May occupy 90% of the volume of a plant cell (central vacuole)

45. Vacuole (in a plant cell)

46. Chloroplast used to trap energy of sunlight during photosynthesis with chlorophyll and convert to energy

47. has a system of flattened membranous sacs called thylakoids

48. Chloroplast
