Presentation Transcript

  1. Test Review

  2. Parts of the Cell • Cell Membrane • Mitochondria • Nucleus • Lysozome • Rough Endoplasmic Reticulum • Smooth Endoplasmic Reticulum • Ribosomes • Microtubules

  3. Transport Into/Out of Cell • Active Transport: takes energy • Endocytosis/Exocytosis • Diffusion/Osmosis

  4. Cell Division • PMAT (prophase, metaphase, anaphase, telophase) • Asexual reproduction vs. Sexual reproduction • Mitosis vs. Meiosis • Sex cells (half cells)

  5. DNA • Adenine (A), Thymine (T), Cytosine (C), Guanine (G) • Genes: the section on DNA that makes a specific protein • Chromosome: 23 pairs of them in each human (23 from mom, 23 from dad) made up of millions of genes each • Mutation: any permanent change in a gene or chromosome

  6. Genetics • Mendel and his pea plants • Alleles (B or b): different forms of genes for different traits (brown hair or blond hair) • Dominant and recessive factors • Punnett Squares • Homozygous (BB or bb) • Heterozygous (Bb) • Genotype: Bb Phenotype: Brown hair

  7. Genetics • Incomplete Dominance: two alleles are dominant to each other (red and white making pink) • Multiple Alleles: more than two possible alleles (blood type has three possible alleles (A, B, and O) • Polygenic Inheritance: many different genes work together for one phenotype (finger prints or eye color)

  8. Habitat • Organism: one individual member of a species • Habitat: where an organism lives • Abiotic/Biotic • Species: a group of organisms that can mate and produce offspring that can mate • Populations: all members of one species living in the same area • Communities: all the populations living in a given area • Ecosystems: all abiotic and biotic factors in a given area

  9. Populations Change in Size • Birth rate and death rate • Immigration and emigration • Population Density • Limiting Factors

  10. Natural Selection • Adaptations • Niche • Competition • Predator/prey • Symbiosis: mutualism, parasitism, and comensalism

  11. Succession • Primary succession • Secondary succession
