Life Science Basics

What is Life Science?

Life science is the study of living things—plants, animals, and humans. This field explores how living organisms grow, reproduce, and interact with each other and their environment.

Key Concepts

  • Cells: The basic building blocks of all living things.
  • Organisms: Individual living things, from bacteria to humans.
  • Ecosystems: Communities of organisms interacting with their physical environment.

Why It Matters

Understanding life science helps us appreciate the diversity of life, protect the environment, and make healthy choices.

Real-World Connections

Doctors use life science to diagnose diseases. Farmers use it to grow better crops. Conservationists use it to protect endangered species.

Examples

  • A veterinarian uses knowledge of animal biology to treat sick pets.

  • A park ranger studies plant and animal interactions to maintain a healthy forest.

In a Nutshell

Life science explores how living things function, interact, and survive.

Key Terms

Cell
The smallest unit of life that can function independently.
