"Classification of Organisms" PPT courseware

Part One: Scenario Introduction

There are about 350,000 species of plants and more than 1.5 million species of animals on the earth. Some of them have similar morphological structures, and some are very different from each other. How do we identify these various species of organisms?

learning target

1. Try to classify organisms based on certain characteristics;

2. Principles, hierarchies, and basic units of biological classification;

3． Practice writing search tables.

When we go to a supermarket with a wide variety of products to buy something, it is easy to find what we need. Why? Because they are classified and arranged according to certain rules. To understand living things, we should also use a method similar to commodity classification, classifying living things according to certain characteristics, which is biological classification.

Classification of living things PPT, part 2: Try to classify living things

Method steps:

1. Identify the species of organisms presented in the picture.

2. The group discusses and formulates the basis for classifying the above-mentioned organisms, and records the discussion results.

3. Classify according to the classification basis, and record the classification results reached by the group members in an appropriate format.

4. The whole class communicates and introduces the classification basis, methods and classification results developed by the group.

discuss:

1.Which group classification methods are more reasonable?

2. Based on the successful experience of each group, how do you think the above-mentioned organisms can be classified more scientifically?

Classification of living things PPT, part three: species and varieties

Horses are divided into wild horses and domestic horses, and domestic horses and many breeds of horses. So, do they all belong to the same species?

A species is a group that shares a common gene pool and is reproductively isolated from other groups. This definition takes the presence or absence of genetic exchange as the main basis for classifying species. Many species of livestock, poultry, and cultivated plants, although morphologically distinct, can interbreed and are therefore merely different varieties of one species.

Classification of living things PPT, part 4: summary

Classification of living things

1. Methods of biological classification

1. Classification units: kingdom, phylum, class, order, family, genus, species.

2. The basic unit of classification “species” is the basic unit of classification.

2. The rules of biological classification

The higher the classification level, the more types of organisms are included and the less they have in common with each other; the lower the classification level, the fewer types of organisms are included and the more they have in common with each other.

3. Naming of organisms: binomial method: genus name + species name
