Life Science: Cells and Genetics

The Building Blocks of Life

All living things are made of cells, the smallest units of life. Cells can be simple (like bacteria) or complex (like plants and animals).

Types of Cells

  • Prokaryotic Cells: Simple, no nucleus (e.g., bacteria).
  • Eukaryotic Cells: Complex, with a nucleus (e.g., plants, animals).

Genetics: The Code of Life

Genetics is the study of how traits are passed from parents to offspring. DNA carries genetic information in all living things.

How Genetics Affects Us

Traits like eye color, height, and even some diseases are inherited through genes. Understanding genetics helps in medicine, agriculture, and solving crimes.

Fun Fact

Humans share about 99.9% of their DNA with every other human!

Examples

  • A family has brown eyes because they inherit the gene for brown eyes from their parents.

  • Scientists use genetic engineering to create crops that resist pests.

In a Nutshell

Cells are the basic units of life, and genetics explains how traits are inherited.

Key Terms

DNA
The molecule that carries genetic information.
Gene
A segment of DNA that determines a trait.
Chromosome
