Virtual Lab: Introduction to the Microscope
|
Macromolecules:
Standard 4.1.1: Compare the structure and function of each of the listed organic molecules in organisms:-Carbohydrates (glucose, cellulose, starch, glycogen) -Proteins (insulin, enzymes, hemoglobin) -Lipids (phospholipids, steroids) -Nucleic Acids (DNA, RNA) Think about it: How are macromolecules formed? How are they broken down in our bodies? |
|
Enzymes: Standard 4.1.3: Develop a cause and effect model for specificity of enzymes - the folding produces a 3-D shape that is linked to the protein function, enzymes are proteins that speed up chemical reactions (catalysts) by lowering the activation energy, are re-usable and specific, and are affected by such factors as pH and temperature. Think about it: What factors can cause an enzyme to denature? What happens when an enzyme denatures? |
Parts of a Microscope:
Standard 1.1.2: Compare prokaryotic and eukaryotic cells in terms of their general structures (plasma membrane and genetic material) and degree of complexity.
Think about it: How do we calculate total power magnification?

Prokaryotic vs. Eukaryotic Cells Standard 1.1.2: Compare prokaryotic and eukaryotic cells in terms of their general structures (plasma membrane and genetic material) and degree of complexity.Think about it: What structures are unique to prokaryotic cells? Eukaryotic cells? |

Cell Organelles:
Standard 1.1.1: Summarize the structure and function of organelles in eukaryotic cells (including the nucleus, plasma membrane, cell wall, mitochondria, vacuoles, chloroplasts, and ribosomes) and ways that these organelles interact with each other to perform the function of the cell. Think about it: While many organelles are the same between plant and animal cells, there are a few that are different. Why do plant cells need a few extra organelles as compared to animal cells? |
Cell Specialization:
Bio.1.1.3: Explain how instructions in DNA lead to cell differentiation and result in cells specialized to perform specific functions in multicellular organisms.
Think about it: What does the term "undifferentiated" mean?

Unicellular Organisms:
Bio.1.2.3 Explain how specific cell adaptations help cells survive in particular environments (focus on unicellular organisms). Think about it: What is taxis? Which organisms would display positive phototaxis? Why? |
