    Study Notes

    Plant Nutrition

    • Plants require essential nutrients like phosphorus, sulfur, calcium, magnesium, and micronutrients like iron, zinc, boron, manganese, chlorine, and molybdenum for growth and development.
    • Macronutrients:
      • Nitrogen: important for leaf growth and overall plant development; deficiency leads to yellowing of leaves and stunted growth.
      • Potassium: vital for maintaining cell membrane potential and turgidity; deficiency results in general poor health symptoms.
      • Copper: component of enzymes and cytochromes; deficiency lowers protein synthesis and may cause chlorosis and twisted leaves.
    • Specialized absorptive structures:
      • Root hairs: increase surface area for nutrient absorption.
      • Root nodules: contain bacteria that help plants obtain nitrogen.
      • Mycorrhizae: symbiotic relationship between fungi and roots for mineral absorption.

    Nutritional Adaptation by Plants

    • Symbiosis of plants and soil microbe:
      • Nitrogen fixation: certain bacteria help plants obtain nitrogen.
    • Mycorrhizae: fungi attach to roots, help absorb minerals, and protect plants from pathogens.

    Plant Parasites

    • Total parasites: rely entirely on their host plants for survival (e.g., dodder).
    • Hemiparasites: can photosynthesize but rely on hosts for water and minerals.

    Animal Nutrition

    • Calorie: unit of energy measurement in food; provides energy for bodily functions.
    • Nutritional requirements of animals:
      • Carbohydrates: major energy source; found in grains, fruits, and veggies; 4 Calories per gram.
      • Proteins: essential for building cell structures, muscles, and bones; 4 Calories per gram.
      • Fats: used for building cell membranes, hormones, and insulation.

    Types of Animals Based on Feeding Mechanisms

    • Substrate-feeders: live in or on their food source (e.g., earthworms, caterpillars).
    • Filter-feeders: filter small organisms and food particles from water (e.g., whales, jellyfish).
    • Fluid-feeders: suck fluids containing nutrients from living hosts (e.g., mosquitoes, leeches, aphids).
    • Bulk-feeders: eat large chunks of food using jaws or adaptations (e.g., lions, bears).

    Digestive Compartments in Animals

    • Food vacuoles: tiny storage compartments in single-celled organisms that break down food with enzymes (e.g., Paramecium).
    • Gastrovascular cavity: simple digestive system with one opening for eating and waste removal (e.g., Hydra, Planaria).
    • Complete digestive system: tube-like system with mouth for eating and anus for waste removal (e.g., humans, many animals).
