A detailed explanation of the textbook of high school biology compulsory one, and what are the conte

Dizzy, buy a reference book.

The content of the high school biology compulsory one is as follows:

1. Cells are the most basic living systems on earth.

2. Arrangement of living systems from small to large: cells, tissues, organ systems, individual populations, community ecosystems.

Biosphere. 3. Scientists determine whether there is a nucleus bounded by a nuclear membrane in the cell.

Divide the cells into eukaryotic cells.

and prokaryotic cells.

4. Amino acids.

is the basic unit that makes up proteins.

All life activities are inseparable from protein, and protein is the main bearer of life activities.

5. Nucleic acid is a substance that carries genetic information in cells, and plays an extremely important role in the genetic variation of organisms and the biosynthesis of proteins.

6. Sugar is the main energy substance, and fat is a good energy storage substance in cells.

7. Biological macromolecules take carbon chains as the skeleton, and the basic units of macromolecules are called monomers, and each monomer is composed of a carbon chain composed of several connected carbon atoms as the basic skeleton, which is connected by many monomers into multimers. Example: The monomers that make up nucleic acids are nucleotides.

The monomers that make up polysaccharides are monosaccharides.

8. Water exists in two forms in cells. A portion of water is combined with other substances inside the cell and is called conjugated water. Most of the water in the cell exists in a free form and can flow freely, which is called free water.

High School Biology Review Strategies

1. Comparative review method

In the review, students are able to use the comparative method to make horizontal and vertical comparisons of knowledge. Such as the comparison of constituent enzymes with inducible enzymes, the comparison of prokaryotic cells and eukaryotic cells, and the comparison of higher plant cells.

and submicroscopic structure comparison of animal cells; The comparison of the three major nutrients and the way to go, the three major nutrients can come from food, except for protein, can be stored, can be partially converted by other substances and so on.

2. Serial review method

When reviewing, the knowledge scattered in each chapter can be connected to enable students to have a comprehensive understanding of the knowledge. For example, the knowledge about proteins is mainly scattered in the section.

I. 2. In Chapter 5, Chapter 1 introduces the constituent elements, basic units, synthesis sites, structure and function of proteins.

Chapter 2 deals with the digestion, absorption, and metabolism of protein in the human body. Chapter 5 talks about the fact that protein synthesis is controlled by genes, including two physiological processes: transcription and translation. When reviewing, you can string these knowledge together to make the knowledge more systematic, which can improve students' ability to solve comprehensive problems.

Most of the knowledge in high school biology textbooks is relatively basic, but there are still many knowledge points that need to be remembered.
