Study Notes

Animal Systems

  • Positive feedback loop examples: Childbirth (oxytocin release), blood clotting (platelet activation), fruit ripening (ethylene production).
  • Negative feedback loop examples: Body temperature regulation (sweating or shivering), blood sugar regulation (insulin and glucagon), blood pressure regulation (baroreceptors and heart rate adjustment).
  • Respiratory System & Homeostasis during exercise: Increased breathing rate and depth provide more oxygen to the muscles, and remove carbon dioxide faster. This helps maintain blood pH balance.
  • Circulatory system importance: Delivers oxygen and nutrients to tissues, removes waste products, and regulates body temperature.
  • Liver & Urea Production: The liver works with the excretory system to produce urea.
  • Digestive tract disruptions: Malfunctions in the digestive tract can lead to issues like indigestion, malabsorption of nutrients, and bowel problems.
  • Parasites & Body systems: Parasites can affect multiple body systems, causing symptoms like anemia (blood), diarrhea (digestive), skin rashes (integumentary), and fatigue (nervous).
  • Childbirth Systems: Reproductive, muscular, nervous, and circulatory systems are all involved in childbirth.
  • Hormone Release Diagram: Hormones are released from glands and travel through the bloodstream to target cells with specific receptors.
  • Respiratory system gas exchange: Oxygen is absorbed from the air into the blood and transported to cells. Carbon dioxide is released from cells into the blood and exhaled.
  • Systems for blood glucose regulation: Endocrine (pancreas releases insulin and glucagon), digestive (absorbs glucose from food), circulatory (transports glucose).
  • Systems involved in defending against viruses: Immune (antibodies and white blood cells), lymphatic (transports immune cells), circulatory (transports immune cells and antibodies).

Plant Systems

  • Waxy cuticle function: Protects the plant from excessive water loss.
  • Vascular plant survival on land: The vascular system, composed of xylem (water transport) and phloem (food transport), allows plants to transport essential materials throughout their bodies.
  • Water and mineral absorption: Roots absorb water and minerals from the soil using root hairs.
  • Stomata opening and closing: Stomata open when the plant needs to take in carbon dioxide for photosynthesis and close to conserve water. They open in the presence of light and close in darkness.
  • Plant tropisms: Phototropism (growth towards light), gravitropism (growth in response to gravity), thigmotropism (growth in response to touch).
  • Water retention during drought: Plants can minimize water loss by closing their stomata, shedding leaves, and developing deep root systems.
  • Fern vs. Mosses: Ferns have vascular tissue and can grow taller than mosses, which lack vascular tissue and are limited to moist environments.
  • Stomata location: Stomata are typically located on the underside of the leaf, minimizing water loss.
  • Flower parts and functions: Petals (attract pollinators), sepals (protect bud), stamen (produces pollen), pistil (contains egg).
  • Plant phyla: Bryophytes (mosses, liverworts), Pteridophytes (ferns), Gymnosperms (conifers), Angiosperms (flowering plants).

Cellular Energetics

  • Oxygen source in photosynthesis: Oxygen comes from the splitting of water molecules during the light-dependent reactions.
  • Light-dependent vs. light-independent reactions: Light-dependent reactions capture light energy and convert it to chemical energy (ATP and NADPH). Light-independent reactions use ATP and NADPH to fix carbon dioxide into sugar.
  • ATP/ADP bond storage and release: Energy is stored in the bonds between phosphate groups in ATP. Energy is released when a phosphate group is removed, converting ATP to ADP.
  • Cellular respiration functions: Breakdown of glucose to produce ATP (energy). Includes glycolysis, Krebs cycle, and electron transport chain.
  • Lactic acid fermentation: Occurs when oxygen is limited, converting pyruvate to lactic acid and producing a small amount of ATP.
  • Gizmo activity: Gas bubbles (oxygen) are produced by photosynthesis. The color of the solution is an indicator of photosynthesis efficiency.
  • Light and photosynthesis correlation: Photosynthesis increases with increasing light intensity up to a certain point.
  • ATP production process: Cellular respiration is the primary process involved in ATP production.
  • Photosynthesis and cellular respiration equations:
  • Photosynthesis: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2
  • Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
  • Diagrams: Draw diagrams for both processes, including the key molecules and steps involved.
