Description
"Try to classify living things" Classification according to the characteristics of living things PPT courseware 8
By studying this section, you will know:
1. What is the basis for classifying organisms?
2. How to classify organisms according to their characteristics?
3. What is the purpose of biological classification?
Think about it, discuss it
If you want to understand the growth, development and behavior of the cabbage butterfly, which one among these books would you choose to read? If you want to know more about moths and frogs, which books should you consult?
Ask students to recall a few questions from the seventh year of enrollment:
1. What are the six major organs of green flowering plants?
2. Do all plants have seeds?
3. Are the seeds covered with pericarp?
4. Are the number of cotyledons in the seeds the same?
5. Are the leaf veins of all angiosperms the same?
6. Do all seedless plants have roots, stems, and leaves?
1. The basis for plant classification is:
Morphological and structural characteristics of plants.
In angiosperms, flowers, fruits and seeds are often used as important basis for classification.
2. The basis for animal classification is:
Characteristics of animals in terms of morphological structure and physiological functions.
3. Purpose of biological classification:
1. Understand the genetic and evolutionary relationships between different groups.
2. Understand biological diversity and protect biological diversity.
Study case detection
1. Biological classification is a basic method for studying organisms. The basis of classification is ()
A. Characteristics of biological forms, structures, etc.
B. Living habits of living things
C. Living environment of organisms
D. Animal behavior
2. Kidney fern belongs to ferns, and sunflower belongs to angiosperms among seed plants. The main difference between the two is ()
A. Whether there are seeds or not B. The structure of leaves is different
C. The structure of the root is different. D. The structure of the stem is different.
3. Among angiosperms, the important classification basis is ( )
A. Differences in rhizome B. Characteristics of leaves
C. Characteristics of reproductive organs D. Characteristics of nutritional organs
4. Among the following plants, which one is not a seed plant ( )
A. Corn B. Sunflower C. Pinus tabulaeformis D. Calabash moss
5. Which of the following plants are seed plants ( )
A Spirogyra B Cucurbita moss C Tomato D Kidney fern
6. A certain plant has roots, stems and leaves, but does not produce seeds. It should be classified as ( )
A Bryophytes B Ferns C Angiosperms D Gymnosperms
7. The picture on the right is a category relationship diagram composed of three circles, in which I is the large circle, II and III are small circles within the large circle respectively. The categories that conform to this relationship are: ( )
A. I cerebrum, II cerebellum, III brainstem
B. I unicellular organisms, II phages, III Chlamydomonas
C. I seeds, II embryos, III cotyledons
D. I mammals, lI bats, III whales
6. Textbook exercises
1. Decide whether the following statements are correct or not
(1) The morphological structures of roots, stems, leaves, flowers, fruits, and seeds of angiosperms can be used as the basis for classification. ( )
(2) In addition to comparing morphological structures, animal classification often also requires comparing physiological functions ( )
2. Among angiosperms, flowers, fruits and seeds are often used as important basis for classification. Please try to analyze the reasons why scientists do this.
Because compared with roots, stems, and leaves, the flowers, fruits, and seeds of plants live for a shorter time, are less affected by the environment, and have relatively stable morphological structures, which can more accurately reflect the evolution and genetic relationships between different plants.
