1. FCAT Review
Life Science

2. What does “Being Alive” mean?
Made of cells
Respond to stimuli
Respire (use energy)
Adapt
Reproduce
Excrete wastes
Secrete
Have a life span

3. Life Needs: Energy (solar or chemical) Water Tolerable Temperatures
Light
Agreeable Atmosphere

4. Structure of the Cell

5. Single Cell vs. Multicellular

6. Cell Organization Atom Molecule Organelle Cell Tissue Organ System
Organism

7. Major Systems
Excretory
Respiratory
Digestive
Male
Reproductive
Female

8. Major Systems
Nervous
Skeletal
Circulatory
Muscular

9. Chemistry of the Cell Cells are made of atoms and molecules
Carbon, Oxygen, Hydrogen, Iron, Sodium, Potassium, etc.

10. Organic Inorganic Organic compounds contain carbon
Carbohydrates, proteins, fats, nucleic acids, etc.
Inorganic compounds are also necessary for life
Water, salt, vitamins, etc.

11. Cell Transport…note error on class notes
Passive Transport
Active Transport
Endocytosis
Exocytosis

12. Cellular Respiration
organisms use oxygen to break down glucose and release water and carbon dioxide as waste
C6H12O6 + 6O2  Energy + 6CO2 + 6H2O

13. Photosynthesis plants use solar energy to make glucose from
water and carbon dioxide
and release oxygen as waste
Energy + 6CO2 + 6H2O  C6H12O6 + 6O2

14. Mitosis
Cell division for body cells - diploid

15. Meiosis
Cell division to produce sex cells - haploid

16. DNA
Nitrogen bases
Adenine
Thymine
Guanine
Cytosine

17. Sexual vs. Asexual Reproduction

18. Heredity – passing of traits from parents of offspring
Alleles – different forms a gene has for a trait
A – dominant allele for a trait (upper case)
a – recessive allele for a trait (lower case)
Heterozygous – different alleles
Homozygous – identical alleles

19. Punnett Squares Tools for predicting genetic crosses
Genotype – genetic makeup
What alleles are present
Phenotype – physical makeup
What is shown

20. Fill in the Punnett Square
T – tall plants
t – short plants
How many offspring plants will be tall?
How many offspring plants will be short?
What percentage of offspring will be tall plants?

21. Fill in the Punnett Square
T – tall plants
t – short plants
How many offspring plants will be tall?
How many offspring plants will be short?
What percentage of offspring will be tall plants?

22. Evolution – changes in kinds of animals and plants over time
Evidence
Fossil record
Continental drift
Why do kangaroos live in Australia?

23. From Eohippus to Equus

24. Survival of the Fittest
Ability to reproduce successfully
Charles Darwin
The fittest?

25. Ecology
Biotic Factors
Living things
Abiotic Factors
Non-living things

26. Food Chain vs. Food Web

27. Energy Pyramid

28. Adaptation for Survival
Changes in
structure
behavior

29. Cycles of Nature
Carbon
Nitrogen
Phosphorus
Water

30. Environmental Issues
Decrease in resources leads to decrease in natural populations
Human activities
Pollution
Global warming
Destruction of habitat

31. Renewable and Non-Renewable Resources
Wind
Solar
Water
Trees
Biomass
Non-renewable
Coal
Oil
Gas

32. Scientific Classification

33. Scientific Classification

34. Dichotomous Key

35. Plant Kindom

36. Plant Reproduction Spores vs. Seeds
Fern
Gymnosperm
Angiosperm

37. Virus
Viruses are not alive until they invade a cell
