1. Science: Final Exam Review

2. Scientists
…and cell theory
Schleiden:
Schwann:
Virchow:
Hooke:

3. Scientists
Schleiden: all plants are made of cells

4. Schwann
- All ANIMALS are made of cells

5. Virchow
- all cells come from cells

6. HOOKE
1st to identify cells (named them)

7. Unicellular vs. Multicellular

8. Autotroph
Heterotroph

9. Heterotrophs
Carnivores:
Herbivores:
Omnivores:

10. Prokaryotes vs. Eukaryotes

11. Know the major cell parts:

12. Cell Transport
Diffusion: High to low
Osmosis: High to low, water ONLY

13. Cell Transport
If it goes LOW to HIGH (uphill); it must be some form of _____________________

14. ACTIVE Transport

15. Respiration vs. Photosynthesis vs Fermentation
Respiration: Breakdown of food to get energy
In mitochondria:

16. Glucose + Oxygen → Energy + Carbon Dioxide+ Water
Respiration
Glucose + Oxygen → Energy + Carbon Dioxide+ Water
C6 H12 O6 + O2 → ATP + CO2 + H20

17. Respiration vs. Photosynthesis vs Fermentation
Photosynthesis: Using sunlight (energy) to make food
In chloroplast:

18. Carbon dioxide + Water → Glucose + Oxygen
Photosynthesis
sunlight
Carbon dioxide + Water → Glucose + Oxygen
Sunlight
CO2 + H2O → glucose + O2

19. Fermentation Getting energy from food WITHOUT using oxygen
Glucose → Energy + Alcohol

20. Review DNA:
Translation
Replication:
Transcription:

21. Base-pairing rule:

22. Cell Cycle

23. Mitosis: 1 cell → 2 cells (body cells)
Chromosome number stays the same (ex: cell starts with 46, each new cell has 46

25. Meiosis: 1 cell → 4 cells (sex cells)
Chromosome number is cut in HALF (ex: cell starts with 46,
4 ending cells each have 23)

26. Genetics: Gregor Mendel
Genotype vs. Phenotype (TT, Tt = tall) Punnett Squares

27. Evolution: by Natural Selection

28. Natural Selection Overproduction Variation Competition
Favorable variations passed on
