Study Notes
Life Processes in Living Organisms
- Nutrition: Autotrophs (like plants) make their own food via photosynthesis, converting light energy to chemical energy. Heterotrophs (like animals) obtain food by consuming other organisms. In humans, digestion breaks down food from ingestion to absorption in the mouth, stomach, and intestines. Photosynthesis is crucial for life on Earth as it's the basis of most food chains.
- Respiration: Aerobic respiration uses oxygen to break down glucose, releasing energy (ATP) in the form of carbon dioxide and water. Anaerobic respiration occurs without oxygen, creating less energy and byproducts like lactic acid in animals or ethanol in yeast.
- Transport: In animals, the circulatory system (heart, blood, blood vessels) carries oxygen, nutrients, and waste. In plants, xylem transports water, phloem transports food.
- Excretion: Kidneys filter blood, removing waste and excess substances to maintain homeostasis in humans. Plants release waste through transpiration (water vapor loss) and root exudates.
Reproduction in Plants and Animals
- Asexual Reproduction: New organisms grow from the parent's body (budding, in yeast, hydra), or a single cell divides (binary fission, in bacteria). Vegetative propagation (new plants grow from parts like roots, stems, or leaves) is common in plants (strawberries).
- Sexual Reproduction: Plants use male (stamens) and female (pistils) reproductive organs in flowers to produce seeds. Fertilization occurs when sperm and egg combine. In humans, fertilization develops a zygote into an embryo.
Diversity in Living Organisms
- Classification: Scientists classify living organisms based on shared characteristics.
- Binomial Nomenclature: Each species gets a two-part scientific name (e.g., Homo sapiens).
