  1. EOC mini Review 1st semester material

  2. Biomolecules

  3. Classification

  4. Classification Questions • This organism is a heterotroph, with cell walls, and Eukaryotic. What kingdom is it? • Fungi • This organism has a nucleus. What Domain is it? • Eukarya • This organism has chloroplast, a nucleus, and is multicellular. Which kingdom is it? • Plantea • This organism is unicellular and is found in extreme environments. Which kingdom is it? • Archeabacteria • This organism is non-motile, eukaryotic, and heterotrophic, with a cell wall. Which kingdom is it? • Fungi

  5. Transport Passive transport- substances move from and area of High Concentration to Low Active Transport- substance move from an area of low concentration to high. Energy required Diffusion- molecules move from an area of High concentration to area of low concentration. Even out Osmosis- diffusion of water across a semipermeable membrane

  6. Tonicity Hypertonic- concentration of water outside of cell is less. Water leaves the cell, cell shrivels and shrinks Hypotonic- concentration of water outside of cell is greater. Water enters the cell, until burst or lysed Isotonic- concentration of water outside of cell is equal. Water enters and leaves at the same rate.

  7. DNA Replication • DNA strand unwinds • New nucleotides are added to the original strands • 2 Strands are now semiconservative. One original strand and one new strand. • DNA Molecules retwist Why is DNA replication important? It is important because when a cell divides, it needs to produce an exact copy of the DNA for the new cell to have the information it needs to carry out its processes.

  8. Cell division Mitosis Meiosis Diploid, Haploid, Crossing over, genetically Identical, genetically unique, body (somatic cell), Gametes

  9. Evolution
