CK-12 Biology Workbook

This book is a big list of biology topics for school. It's like a table of contents from a science textbook. It's called a "Biology Workbook."

The book has many chapters. Each chapter teaches about living things and how they work.

Some chapters talk about tiny cells. Cells are the small building blocks that make up all living things.

Some chapters talk about plants. They tell how plants grow and make their own food using sunlight.

Some chapters talk about animals. They tell about animals with backbones, like fish, birds, and mammals. They also tell about animals without backbones, like insects and worms.

Some chapters talk about the human body. They tell about bones, muscles, skin, and how our body parts work together.

Some chapters talk about genes. Genes are tiny instructions inside our bodies that tell us what we look like and how we grow.

Some chapters talk about evolution. Evolution means how living things slowly change over a very long time.

Some chapters talk about ecology. Ecology means how living things and their homes, like forests or oceans, work together.

The book was made by a group called CK-12 Foundation. They want to help students learn science for free. People can use this book to learn and can share it with others too.
