22. Life Sciences  Explain that cells are the basic unit of structures and function of living organisms, that once life originated all cells come from pre-existing cells, and that there are a variety of cell types.  Basic units of life  We have evolved from single-celled organisms  Different cells have different jobs.

23. Life Science  Eukaryotic Cell Has cell membrane  Allows material to enter and leave the cell. Nucleus-contains DNA Mitochondria-energy is stored and used, contains DNA ER- transportation system within the cell Ribosomes- protein is made Vacuoles- closets, store stuff

24. Life Science  Cell Wall Function is protection, support, structure.  Chloroplasts Contain chlorophyll Make the plant green Function is to produce food

25. Life Cells  RBC Form is round Function is fit through our circulatory system  Hair Form is wide on bottom and thin at top Function is for root stability hair formation  Sperm Form head and tail Function is to swim by using the flagellum

26. Life Sciences  Explain the characteristics of life as indicated by cellular processes and describe the process of cell division and development. Cells must divide to reproduce. Cells produce an exact copy of the cells they replace. Cells go through phases of change.  Prophase, metaphase, anaphase, telephase

27. Life Science meiosis

28. Life Sciences  Explain the genetic mechanisms and molecular basis of inheritance. Form and function of Deoxyribose Nucleic Acid (DNA) Genes- traits Alleles- one part of two that make up a gene Mutations- is the only source of new genetic material Sex-linked traits- traits carried by either a male or female

29. Life Sciences  Explain the genetic mechanisms and molecular basis of inheritance. Genotype  What you are, in your genes Bb- heterozygous dominant brown-eyes Phenotype  What you look like, photograph Brown-eyes

32. Life Sciences  Explain the structure and function of ecosystems and relate how ecosystems change over time. Biotic- living components of an ecosystem Abiotic-nonliving components of an ecosystem

33. Life Sciences  Describe how human activities can impact the status of natural systems. GMOs- Genetically Modified Organisms  Scientist change the organism DNA to improve its ability to live  BT- Bacilis thuringensis has been added to cotton plants to produce a poison to protect it from bugs. Killing bugs, cotton is poisonous, cotton grows faster and bigger, grow more cotton, need more land, eliminates ecosystems, food chain is disrupted, poison goes through food chain.

34. Life Sciences  Describe a foundation of biological evolution as the change in gene frequency of a population over time. Natural Selection- Charles Darwin “Origin of Species”- survival of fittest  Offspring are more likely to survive due to Genetic, traits, genes, alleles, mutations  Ability to reproduce  Ability to move  Ability to attract a mate  Ability to support family  Ability to get food  Genetics that allow you to grow

35. Life Sciences  Explain how natural selection and other evolutionary mechanisms account for the unity and diversity of past and present life forms. Natural selection determines the survival of the fittest  Separates organisms to create diversity in our world.
