Summary
The topic covers the characteristics and classification of living organisms, focusing on how organisms are grouped and identified based on shared traits.
- Growth — increase in size and mass over time Example: A seed germinates and becomes a plant.
- Reproduction — process by which organisms produce new individuals Example: Flowers produce seeds for new plants.
- Sensitivity — ability to respond to stimuli Example: A lizard detaches its tail when threatened.
- Nutrition — obtaining food for energy and growth Example: Plants use photosynthesis to make food.
- Respiration — process of releasing energy from food Example: Yeast ferments sugar to produce energy.
- Binomial Nomenclature — system of naming species using two terms: genus and species Example: Homo sapiens, where Homo is the genus and sapiens is the species.
