    Study Notes

    Biology Final Exam - Study Notes

    • Cell Structure & Function:

      • Chloroplasts are responsible for sugar and starch production, and give plants their green color.
      • Mitochondria are responsible for cellular energy production.
      • Cell walls provide structural support in plant cells.
      • Cellulose is a structural component in plant cell walls.
      • Humans use oxygen (O2) produced through photosynthesis.

    • Photosynthesis & Respiration:

      • The independent variable in Mr. Baird's experiment is the type of fertilizer.
      • ATP is used for various cellular processes such as building proteins, transporting molecules, and cell division (mitosis).
      • Photosynthesis uses sunlight instead of ATP.
      • Water molecules are held together by hydrogen bonds.

    • Water Properties:

      • Cohesion allows water to cling to surfaces (like blades of grass).
      • Water acts as a universal solvent.
      • High heat of vaporization is a property of water.

    • Cellular Processes:

      • Glucose can be broken down for energy during cellular respiration.
      • Glucose is a product that can be used during respiration.
      • Cellulose production occurs in the cell wall.
      • Plants use glucose in cellular respiration.

    • Scientific Method:

      • Independent variables are tested to see if they cause a change in other variables.
      • Dependent variables are results measured in an experiment.

    • Plant Biology:

      • Fertilizer type can affect plant growth, as investigated by Mr. Baird.

    • Macromolecules:

      • Different macromolecules have different functions in cells (e.g., energy storage, structure, genetic information).

    • Cell Biology:

      • Mitochondria are involved in cellular energy production,
      • Chloroplasts are specialized organelles for photosynthesis in plant cells.
      • Cell walls, a key component of plant cells, provide structure and support.

    • Cellular Respiration:

      • Cellular respiration uses glucose for cellular energy.

    • Photosynthesis:

      • Photosynthesis converts light energy into chemical energy (glucose).
      • Photosynthetic processes use water, carbon dioxide, and sunlight to produce glucose.

    • Additional Information:

      • Water molecules are polar (have slightly positive and negative charges),
      • Polarity of water affects its properties, such as cohesion and the ability to dissolve certain substances.
      • Polarity is critical in chemical reactions.
      • The diagram showing Earth's seasons demonstrates the Earth's position in relation to the sun and how this affects the seasons.

    • Bonus Questions:

      • 31: Viruses are not considered living things because they lack cellular structure and are unable to replicate independently.
      • 32: Carbohydrates are the type of biomolecule that includes glucose.
      • 33: Bonus questions are open-ended and require creative thought.
