Introduction to Biology

Definition of Biology

• "Bio" means living, "logy" means study.
• Biology: Study of living things.

Characteristics of Living Things

1. Order

   • Organized structure (e.g., rose petals folded around a center with seeds).
   • Basis: Living cells.

2. Reproduction

   • Organisms reproduce their own kind (e.g., pandas give birth to pandas).

3. Growth and Development

   • Controlled by inherited DNA.
   • Organisms often resemble their parents.

4. Energy Processing

   • Organisms use energy from food to power activities and chemical reactions.

5. Response to Environment

   • Organisms respond to stimuli (e.g., humans laugh when tickled).

6. Regulation

   • Internal environment regulation (homeostasis).
   • Example: Lemurs sunbathe to regulate body temperature.

7. Evolutionary Adaptation

   • Adaptations evolve over generations for survival (e.g., lions' camouflage in the savanna).
