Study Notes
Microscope Parts
- Body tube: Connects the eyepiece to the objectives.
- Ocular (eyepiece): The lens you look through.
- Objective lenses: Cylindrical lenses with different magnifications (e.g., 10x, 40x).
- Stage: Platform holding the slide.
- Diaphragm: Rotating disc adjusting light.
- Light source: Lamp or mirror providing illumination.
- Coarse adjustment knob: Large knob for initial focusing.
- Fine adjustment knob: Small knob for precise focusing.
- Base: Stable bottom of the microscope.
Cell History
- Robert Hooke: Discovered empty cells in cork.
- Matthias Schleiden: Proposed all plants are composed of cells.
- Theodor Schwann: Proposed all animals consist of cells.
- Rudolph Virchow: Stated cells only arise from preexisting cells.
- Anton van Leeuwenhoek: Observed microorganisms.
Types of Cells: Animal Cell
- Nucleus: Large, round structure housing DNA.
- Rough Endoplasmic Reticulum: Folded layers near the nucleus with ribosomes (dots).
- Golgi Body: Stacked, flattened sacs resembling pancakes.
- Mitochondria: Oval-shaped with inner folds (cristae).
Water Properties
- Cohesion: Water molecules stick together.
- Adhesion: Water molecules stick to other surfaces.
- Surface Tension: Allows small organisms to walk on water.
- Capillarity: Ability of water to move up thin tubes.
- High Specific Heat: Water absorbs/releases heat slowly.
- Universal Solvent: Dissolves many substances.
Solutions and Osmosis
- Isotonic: Solute concentration equal inside/outside the cell.
- Hypertonic: Higher solute concentration outside the cell; cell loses water.
- Hypotonic: Higher solute concentration inside the cell; cell gains water.
Cell Transport
- Endocytosis: Large substances enter the cell.
- Exocytosis: Large substances leave the cell.
- Diffusion: Movement of molecules from high to low concentration.
- Molecular Transport: Movement through proteins.
- Osmosis: Water molecule movement.
Biomolecules: Carbohydrates
- Monomers: Monosaccharides (e.g., glucose).
- Bio-elements: C, H, O.
- Bonds: Glycosidic bonds link monosaccharides.
- Function: Quick energy source and structural support.
Biomolecules: Lipids
- Monomers: Fatty acids and glycerol.
- Bio-elements: C, H, O.
- Bonds: Ester bonds link fatty acids to glycerol.
- Function: Long-term energy storage, cell membranes, insulation.
Biomolecules: Proteins
- Monomers: Amino acids.
- Bio-elements: C, H, O, N, S.
- Bonds: Peptide bonds link amino acids.
- Function: Enzymes, hormones, structural roles, and transport.
Biomolecules: Nucleic Acids
- Monomers: Nucleotides (sugar, phosphate, nitrogenous base).
