| Question | Answer |
| The function of the Cell Wall | Provides support and structure the cell |
| The function of the Cell Membrane | Controls what enters and exits the cell |
| The function of the Nucleus | Controls the cell (like the brain of the cell) |
| The function of the Cytoplasm | Where chemical reactions occur |
| Eukaryotic Cells have _______ | A Nucleus |
| Prokaryotic Cells have _______ | No Membrane-Bound Organelles (Such as Nuclei) |
| The Function of the Bacterial Capsule | Protection from other Substances (such as Stomach Acid) |
| The Function of the Bacterial Chromosomal DNA | Controls the Cell without the Nucleus and contains DNA |
| The Function of the Bacterial Plasmid DNA | Contains DNA that can be Passed between Bacterium and Genes for Resistance |
| The Function of the Bacterial Pili | Sticks Cell to Host Cells or Surfaces |
| The Function of the Bacterial Flagella | Tail-like Structure used for Movement (Spins) |
| The Function of the Ribosome | Produces Protein from Amino Acids and Subunits |
| What Unit Uses "m"? | Metres |
| What Unit Uses "mm" | Millimetres |
| What Unit Uses "μm" | Micrometres |
| What Unit Uses "nm" | Nanometres |
| What Unit Uses "pm" | Picometres |
| Order of Measurements | Metre, Millimetre, Micrometre, Nanometre, Picometre |
| How do you get to Each Measurement | Multiply by 1000 to go smaller Divide by 1000 to get bigger ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°) |
| Microscope Triangle / Microscope Calculation | Size of Image ---------------------- Actual Size | Magnification Size of Image = Actual Size * Magnification |
| Name Four Adapted Structures in a Sperm Cell and Their Functions | Acrosome - Contains Enzymes Haploid Nucleus - Contains Half of all Chromosomes Mitochondria - Releases Energy for Quick Movement Long Tail - Moves Side to Side to Move the Cell Forward ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°) |
| Name Four Adapted Structures in an Egg Cell and Their Functions | Cytoplasm - Large Store of Nutrients for the Embryo Haploid Nucleus - Contains Half of all Chromosomes Cell Membrane - Hardens after Fertilisation Jelly Layer - Hardens after Sperm and Egg Nuclei Fuse ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°) |
| Name an Adapted Structure in a Ciliated Epithelial Cell and Their Functions | Fine Hair-Like Exteriors - Sweep from Side to Side to Move Things across the Cell Surface |
| Name Factors of Light Microscopes Compared to Electron Microscopes | Uses Light to see Specimens Lower Magnification Lower Resolution Cheaper Smaller Magnification of up to 2000x Lenses made of Glass Specimen can be Dead or Alive :O |
| Name Factors of Electron Microscopes Compared to Light Microscopes | Higher Magnification Higher Resolution Extremely Expensive very cash money Very Large ( ͡° ͜ʖ ͡°) Uses Electrons to VIew Specimen Specimen need to be Deaded :O :( Operates under a Vaccum Lenses are made of Electromagnets |
| Name the Main Differences of Transmission Electron Microscopes (hoi im tem) and Scanning Electron Microscopes (SEM) | TEM: Electrons Pass-Through Up to x1,000,000 Magnification Very Thinly Sliced Specimen 2D Images SEM: Electrons Bounce Off the Surface Specimen can be Thicker Up to x30,000 Magnification |
