Reading outline P85-89

1. Why classify organisms?

2. What are the classification units from large to small?

3. What is the most basic classification unit?

4. Which level of creatures has the most common characteristics?

take a look

How are horses classified into different hierarchical taxonomic units?

Each horse is an individual animal, but all horses belong to the same species of animal.

Zebras are very similar to horses except that their hair is black and white striped. Other characteristics of zebras are very similar to horses. Zebras and horses are classified into the same genus - Equus.

Donkey is an animal of another genus. It is smaller than horses and zebras, but it has many common features with Equus: the third toe is well-developed and hoofed, and the remaining toes are degenerated. They are classified into the same family - Equidae.

Rhinoceros does not belong to the horse family. Its feet have not one toe, but three toes, with hooves at the end. But it and equids have an odd number of hooves on each foot, and both belong to the order Perissodactyla.

summary:

The species horse belongs to the genus Equus, the family Equus, the order Perissodactyla, the class Mammalia, the phylum Chordata, the vertebrate subphylum, and the kingdom Animalia.

Each species of plants can also be assigned to the corresponding genus, family, order, class, phylum, and kingdom using the same method.

Peach belongs to the genus Prunus, Rosaceae, order Rosaceae, class Dicotyledon, and subphylum Angiosperm of seed plant phylum.

Think about it:

What is the significance of scientifically classifying living things according to different levels of taxonomic units?

Learn about biological diversity,

Protect biological diversity

practise

1. Among the seven levels of kingdom, phylum, class, order, family, genus and species, which level of organisms do you think has the most common characteristics? Which one is the least? Give your reasons.

Organisms within a species have the most common characteristics, and organisms within a kingdom have the least common characteristics. Because the classification method is based on the differential characteristics of organisms, the higher the classification level, the greater the differences between organisms it contains, that is, the fewer common characteristics, and vice versa. Species is the lowest of the seven levels, and therefore, the creatures in this level have the most common characteristics.

Kingdom Prokaryotes: This kingdom includes all organisms that lack a nuclear membrane, mainly bacteria.

Kingdom Protista: Protists include simple eukaryotic organisms (that is, having a true nucleus), which are single-celled organisms. This kingdom is the lowest among eukaryotes.

Biological Nomenclature and Plant Listing

1. In botanical gardens or parks, we can often see signs with various plants. The names of the plants are written on the signs. Please think carefully. In addition to the names of the plants, which of the classification units is usually written on them. grade?

2. Are biological individuals of the same species more closely related, or are biological individuals in the same world more closely related?

3. The significance of biological classification:

Understand the diversity of organisms, determine the position of a certain species in biological classification, and further clarify the genetic relationships between organisms. The study of biological evolution and the protection of biological diversity are of great significance.

Consolidation exercises

1. Which of the following statements about species is incorrect: ( )

A. Organisms of the same species must belong to the same genus

B. Organisms of the same species can produce reproductive offspring through sexual reproduction.

C. Organisms of the same species have the most common characteristics

D. A horse is a species

2. Please arrange the following creatures in order from distant to nearest in relation to humans:

Cow, chimpanzee, cabbage, earthworm, fish, E. coli

Answer: E. coli, cabbage, earthworms, fish, cattle, chimpanzees

think

The king of beasts (an old tiger) unfortunately passed away. Unfortunately, the king left no descendants. Who will inherit the billions of property left by the king? According to the inheritance law of the animal kingdom, the animal closest to the king inherits.

It should be awarded to me. I am the king's short brother. I am most like my elder brother. We all belong to the cat family

Your Honor, the verdict should be given to me. Tiger and I are brothers in the same phylum. We both belong to the phylum Vertebrates.

It should be awarded to me. Everyone knows that "the fox fakes the power of the tiger". The tiger king is my bodyguard, and they are all carnivores.

Your Honor, the verdict should be awarded to me, the old pig. Both the tiger and I belong to the class Mammalia.
