What is Biology?

Introduction

• This lecture explains the concept of Biology using animations and illustrations.
• It is part of a series titled "Biology Made Ridiculously Easy."

Definition of Biology

• Biology is the study of living things.
• The term is derived from two Greek words: "Bio" meaning life, and "logy" meaning study.

Key Concepts in Biology

1. Order

• Living things have a complex but organized structure.

2. Reproduction

• Organisms have the ability to reproduce, creating offspring.

3. Growth and Development

• Organisms grow and develop following specific instructions coded in their DNA.

4. Energy Processing

• Living organisms need energy to perform life processes.

5. Response to Environment

• Organisms respond to environmental changes.

6. Regulation

• Living things regulate their internal environment to maintain a stable and constant condition (homeostasis).

7. Evolutionary Adaptation

• Over generations, organisms evolve adaptations that better suit their environment.

Examples of Things Studied in Biology

• Biology encompasses a broad range of fields such as:
  • Neurobiology
  • Ecology
  • Biophysics
  • Microbiology
  • Systematics

Conclusion

• Biology is a broad and diverse field that seeks to understand life from the molecular level to ecosystems.
• It is not just about understanding what life is, but also how it functions and evolves.
