Study Notes
Biology Study Notes
-
Compound Microscope: Used to magnify small cells. It uses lenses and a light source. It is the most common and versatile type of microscope.
-
Magnification: The process of enlarging the appearance of a specimen. It is achieved using a lens system. A 2x magnification makes a specimen appear twice as large. Compound microscopes use an ocular (eyepiece) and objective lens.
-
Microscope Parts: Microscopes have parts like the eyepiece (magnifies 10x), low-power objective (4x), medium-power objective (10x), and high-power objective (40x) lenses. Magnification of different lenses are multiplied together to determine the total magnification.
-
Field of View: The circular area viewed through the eyepiece. The field of view decreases with higher magnification.
-
Microscope Safety: Always keep the microscope upright. Use two hands to carry it, one under the base and one on the arm. Use the microscope near the center of the desk or table. Be careful with glass slides, as they can shatter. Do not look directly at the sun through the microscope, and keep both eyes open while using the scope. Store the microscope with the lower-power objective lens in place and the stage lowered. Dry hands and area are important. Unplug the microscope by pulling on the plug (not the cord).
-
Biological Drawings: Use circles to represent the field of view. Draw what is seen clearly with short, firm strokes. Use clear labeling of magnification.
-
Determining Total Magnification: Multiply the magnification of the eyepiece and the objective lens being used. (e.g., 10x eyepiece * 40x objective = 400x total magnification)
-
Cell Theory: The cell is the basic unit of life. All organisms are made of one or more cells. All new cells arise from pre-existing cells.
-
Prokaryotic vs. Eukaryotic cells: Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus. Eukaryotes are generally larger and more complex.
-
Cellular Processes (Photosynthesis/Cellular Respiration):
-
Photosynthesis: A process that converts light energy to chemical energy. Plants use carbon dioxide and water to create glucose (sugar) and oxygen.
-
Cellular Respiration: A process where living things break down food molecules to release stored energy. It uses glucose and oxygen to produce energy (ATP), carbon dioxide, and water. Photosynthesis and cellular respiration are complementary processes that cycle matter and energy in ecosystems.
