Biology Semester I Final Review Sheet 2013-2014 *4 unifying themes of biology: choose one and give an example of study we've done so far *metabolic processes (photosynthesis, cellular respiration, glycolysis, fermentation): explain why organisms need these processes *explain photosynthesis: include organelle in which it takes place, the energy conversion that takes place *explain cellular respiration: include organelle in which it takes place, the energy conversion that takes place *3 important functions of the cell membrane *3 principles of cell theory: choose one to relate to current studies *cell transport: compare active and passive transport methods and why both are necessary *explain why water's unique properties are important to cellular functioning *4 biomolecules: list and give one important feature *type of energy used by cells and the molecule that carries it *cell cycle-- phases and what occurs at each *why most cells are in interphase and not mitotic phases *4 comparisons of mitosis and meiosis *explain why apoptosis is important to cell regulation *explain what happens if cells grow out of control *explain the benefits of stem cells; which ones are considered controversial and why *explain why meiosis has two rounds of cell division *explain 2 avenues to genetic diversity *Explain one of Mendel's contributions to the foundational knowledge we have of genetics and how traits are inherited *explain the difference between genotype and phenotype
