Cells
1.2 Section 22-34

2. Spontaneous Generation

3. Spontaneous Generation

4. Cell Theory All living things are made of cells
Cells come only from other cells
Cells are the building blocks of life

5. DIVERSE
Cells are diverse in nature
vary in size, shape,

6. ONE OR MORE
One Cell
More than One Cell

7. BALANCE Cells must constantly balance certain life processes:
Intake and storage of nutrients
Growth
Response to stimuli
Exchange of gases
Waste removal
Reproduction

8. Cells
Prokaryotes
Bacteria
Eukaryotes
Plant cells
Animal cells

9. Prokaryote Cell
Simple cells
No organelles

10. Eukaryotic Cells
Complex Cells
Have Membrane Bound Organelles

11. ANIMAL CELLS AND PLANT CELLS
Basic Components
Animal Cells
Specific Features
Plant cells

12. ANIMAL CELL OVERVIEW

13. PLANT CELL OVERVIEW

17. ORGANELLES
Organelles are specific structures that carry out specific tasks

18. CYTOPLASM
Jelly-like fluid that contains organelles

19. Cell Membrane
A thin outer covering that regulates the movement of materials into and out of the cell

20. Cell Wall Plant Cells ONLY Structure that surrounds the cell membrane
Helps to protect and maintain shape of cell

21. Nucleus In most cells the largest organelle Central Command
Directs all cellular activities:
Movement
Growth
Contains the cell’s genetic material or DNA

22. Vesicles & Lysosomes
Vesicles act as temporary storage compartments (transport proteins)
Lysosomes break down food particles, cell wastes, and worn-out organelles.
Much smaller than Plant Vacuoles

23. Vacuole Plant Cells VERY VERY LARGE
Sometimes occupying up to 80% of the entire cell
Act as storage compartments for waste products and Water

24. Ribosomes
Protein synthesizers – makers of protein

25. Mitochondria Single = Mitochondrion Power Plant of the cell
Makes Energy required for Cellular processes

26. Mitochondria
Cellular Respiration
C6H12O6 + 6O2  6CO2 + 6H2O

27. Chloroplast Plant Cells ONLY
Carries out photosynthesis – makes energy for plants
IS GREEN!!!

28. Chloroplast
6H2O + 6CO2  C6H12O6 + 6O2

29. Endoplasmic Reticulum
Two forms: Smooth and Rough Endoplasmic Reticulum
Where of proteins and fats (lipids) are made
Studded with Ribosomes

30. GOLGI BODY Process and sort proteins for transport outside of the cell

33. Bacteria and Viruses

34. Bacteria One-celled living organisms Prokaryotes
Smaller than plant or animal cells

35. Prokaryote vs Eukaryote WS 2-1 Page
Small
No membrane bound organelles
Genetic Material (DNA), ribosomes, cell wall and cell membrane, cytoplasm
Larger
Complex with membrane bound organelles (like nucleus, ER, Golgi body)
Genetic Material (DNA), ribosomes, cell wall (Plants Only) and cell membrane, cytoplasm

36. Bacteria Size

37. Bacteria Come in 3 basic shapes cocci (spheres) bacilli (rod shaped)
spirilla (corkscrew shape)

38. Bacteria SHAPE

39. Beneficial Bacteria
Found in our digestive tracts and in the digestive tracts of all animals –
help to break down our food

40. Beneficial Bacteria Bacteria are used to make many commercial products
Cosmetics
Cheese
Bread

41. Bad Bacteria Bacteria can invade both plant and animal cells
Bacteria produce toxins which kill or affect the normal functioning of cells

42. Bacteria REPRODUCTION
bacteria double in number every minutes under ideal conditions!
1 bacteria could fill the gym within 24 hrs under ideal conditions! 

43. Viruses Are not cells Are very tiny
Must be in a living cell in order to reproduce
Not “ALIVE” until inside a host cell

44. Viruses – variety of shapes and sizes

45. Viruses – variety of shapes and sizes

46. Virus
Bacteria
Animal Cell

47. Viruses Are PARASITES
Hijack the cell’s machinery to produce copies of itself
Most of the time the host cell is killed in the end

48. Viruses that attack human cells
HIV
Influenza
Small Pox
Measles
Polio
Ebola
Vaccines are available for some but not all viruses

49. Zika Virus
