Study Notes
Nutrition
- Definition: The process organisms use to acquire and utilize food.
- Types:
- Autotrophic: Organisms (like plants) make their own food using photosynthesis.
- Heterotrophic: Organisms (like animals, fungi) obtain energy from other organisms.
- Key Concepts: Photosynthesis, enzymes, and digestion are crucial to this process.
Respiration
- Definition: Breaking down glucose to release energy in the form of ATP.
- Types:
- Aerobic: Requires oxygen (e.g., humans).
- Anaerobic: Does not require oxygen (e.g., yeast, muscles during exertion).
- Aerobic Respiration Equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP)
Transportation
- Definition: Moving substances (nutrients, gases, waste) within the body.
- Animal Transportation: Accomplished through the circulatory system (heart, blood vessels, blood), transporting oxygen, carbon dioxide, and nutrients.
- Plant Transportation:
- Xylem: Transports water and minerals from roots to the leaves.
- Phloem: Transports food (sugars) from leaves to other plant parts.
Excretion
- Definition: Removing metabolic waste from the body.
- Human Excretion: Carried out by the excretory system (kidneys, ureters, bladder, urethra) to eliminate urea, excess salts, and water.
- Plant Excretion: Occurs through stomata, lenticels, and vacuoles.
Interconnectedness
- All these life processes are interconnected, working together to maintain homeostasis.
- The chapter highlights crucial experiments demonstrating the role of sunlight and chlorophyll in photosynthesis.
