Study Notes
Cell Parts and Functions
- Nucleus: Controls cell activities, stores DNA
- Cell Membrane: Regulates substance movement in and out of the cell, provides protection
- Cytoplasm: Holds organelles, supports chemical reactions
- Mitochondria: Generates energy (ATP) through cellular respiration, regulates metabolism
- Endoplasmic Reticulum (ER): Rough ER synthesizes proteins, smooth ER synthesizes lipids and detoxifies substances
- Ribosomes: Synthesize proteins from amino acids
- Golgi Apparatus: Modifies, packages, and transports proteins and lipids produced by the ER
- Lysosomes: Contain enzymes that digest waste, old cell parts, and foreign invaders
- Vacuoles: Store nutrients, waste products, maintain cell shape (larger in plant cells)
- Cytoskeleton: Provides structural support, shape, and aids in cell movement
- Centrioles: Organize spindle fibers during cell division in animal cells
- Chloroplasts: Perform photosynthesis, converting light energy into chemical energy (in plant cells)
- Cell Wall: Provides structural support and protection, maintains cell shape (in plant cells)
Organ Systems
- Circulatory System: Heart pumps blood, arteries carry oxygenated blood, and veins carry deoxygenated blood
- Digestive System: Organs like mouth, esophagus, stomach, and intestines that break down food for absorption
- Respiratory System: Organs like nose, trachea, lungs, and alveoli involved in gas exchange (oxygen intake and carbon dioxide release)
Cell Cycle and Mitosis
- Interphase: Cell growth and preparation for division
-
Mitosis:
- Prophase: Chromosomes condense
- Metaphase: Chromosomes align in the middle
- Anaphase: Chromosomes separate
- Telophase: Nuclear membranes reform
- Cytokinesis: Division of the cytoplasm
Microscope Calculations
- To convert millimeters to micrometers, multiply by 1000
- Field of View (FOV): Use formulas to calculate FOV at different magnifications (e.g., low power, high power)
Cell Types (Size & Function)
- Red Blood Cells (RBCs): Transport oxygen, contain hemoglobin, lifespan ~120 days
- White Blood Cells (WBCs): Fight infections (types include lymphocytes and neutrophils)
- Platelets: Help in blood clotting, lifespan 7-10 days
Cancer and Normal Cells
- Normal Cells: Controlled growth, specialize in functions, die naturally when damaged/old (apoptosis)
- Cancer Cells: Uncontrolled growth, fail to specialize, remain immature, invade surrounding tissues (metastasis)
Causes and Treatment of Cancer
- Causes: Genetic mutations, environmental factors, carcinogens
- Treatments: Surgery, chemotherapy, radiation therapy, immunotherapy
Specialized Cells
- Nerve Cells (Neurons): Transmit signals
- Muscle Cells: Contract for movement
- Red Blood Cells: Transport oxygen
Stem Cells
- Definition: Undifferentiated cells that can become specialized cells
- Types: Embryonic stem cells (can become any cell type), adult/tissue stem cells (specialize in limited cell types)
Organ Transplantation
- Definition: Replacing a failing or damaged organ with a donor organ
- Donor Types: Living donors, deceased donors (kidney, liver, lung, bone marrow, heart, pancreas, intestines)
