BSC1010C Study Guide - Midterm Guide: Numerical Aperture, Elodea, Cell Membrane
Document Summary
Resolution (d) is equal to the distance between 2 points at which they can be distinguished as separate from each other. As d gets smaller, resolution gets better: d = y / na. Lambda (y) represents wavelength of light; na stands for numerical aperture. Compound light microscope increases our ability to see detail by 1000x. Eukaryote cell have a nucleus and other membrane bound organelles; include plants, fungi, protists, and animals. Prokaryotic cells bacteria, no nucleus or membrane bound organelles. Plant cells contain organelles called chloroplasts that aid them in photosynthesis. All cells have plasma membrane, dna and ribosomes. Lab observation of letter e, threads and elodea. Scientific method: observation, hypothesis, experiment, analysis and results/conclusion. Dependent variable factor that is measured. Control group gives you a baseline to compare your manipulations against. Sample size the # of observations; increased by conducting the same experiment multiple times. Replicate each instance of conducting an experiment.
