1, determine the central theme: determine the title of Chapter 3 as the central theme, such as "Basic Structure of Cells".

2. Grading topic: According to the content of Chapter 3, the topic is divided into several sub-topics, such as cell membrane, nucleus, organelles, etc.

3. Add details: Under each sub-topic, add relevant details, such as the functions and features of each component.

4. Use graphics: You can use graphics, charts, colors, etc. Emphasize key points, such as using lines or shapes of different colors to represent different components.

5, concise and clear: try to keep the mind map concise and clear, avoid using too many words and graphics, so as not to confuse readers.

6. Export and share: After completing the mind map, you can export it to a picture or PDF format and share it with people who need it.

Extended data:

The first chapter of "Into the Cell", a compulsory course of biology in senior high school, mainly tells the basic concept of cell, its structure and function, and its diversity. Cells are the basic units of living things, and all living things are made of cells, which have the ability of self-replication and are the basic places for life activities.

The diversity of cells is explained, including the differences between prokaryotic cells and eukaryotic cells, as well as the differences in morphology, structure and function of different types of cells. Mind mapping, one of the compulsory courses in senior high school biology, mainly describes the basic concept of cells, the structure and function of cells, and the diversity of cells in the first chapter of Walking into Cells, one of the compulsory courses in senior high school biology published by People's Education Press.

Cells are the basic units of living things, and all living things are made of cells, which have the ability of self-replication and are the basic places for life activities. The diversity of cells is explained, including the differences between prokaryotic cells and eukaryotic cells, as well as the differences in morphology, structure and function of different types of cells.

Cell composition:

In the chapter "Molecules Composed of Cells", it is introduced that cells are mainly composed of organic matter and inorganic matter. Organic substances include carbohydrates, lipids, protein and nucleic acids, while inorganic substances include water and inorganic salts. Carbohydrate is the main energy source of cells, and lipid is the main component of cell membrane.

At the same time, it also has the functions of energy storage and heat preservation. Protein is the most important organic molecule in cells, which has many functions, including catalysis of enzymes, structural support and signal transmission. By studying this chapter, we can understand the chemical composition of cells and the structure and function of important molecules.
