Biology as a system of sciences Biology life science (from Greek bios life, logo science) a system of sciences about living organisms, their structure, vital processes, the relationship between themselves and the environment, origin, diversity, patterns of development, studies the laws of life and development of living things refers to the natural sciences

Biology - This is a collection of wildlife sciences From Greek. “Bios” - “life”, “logos” - “science. The subject of her research. The variety of manifestations of life: The structure and functions of living organisms, natural communities; Their origin and distribution; Communication with each other and inanimate nature. The variety of manifestations of life: The structure and functions of living organisms, natural communities; Their origin and distribution; Communication with each other and inanimate nature.

3. The emergence of ancient states (Greece, Rome) Systematization of knowledge about man, plants, animals AristotleTeofrast Galen Described about 500 species of animals. Created the first system for their classification. He laid the foundations of comparative anatomy. He believed that living matter arose from the inanimate "Father" botany. Described various plant organs. He laid the foundation for the classification of plants. He believed that living matter arose from the inanimate outstanding Roman physician. The "father" of medicine. Described human organs. He laid the foundations of human anatomy. The basis for the development of European biological science, did not change until the VIII century. AD

Aristotle (384–322 BC) Galen (BC) Theophrastus (372–287 BC) Outstanding scholars Dr. Greece

4. The Middle Ages (V – XV centuries A.D.) Inhibition of the development of biology, the prevalence of religious beliefs about the creation of matter by God. Biology developed mainly as a descriptive science. The accumulated facts were often distorted. Alchemy was developed.

5. The Renaissance (XVI – XVIII centuries AD) The development of biological science, the study of the structure and functions of various biological objects Robert Hook (1635–1703) The invention of the microscope, the introduction of the term “cell” Anthony van Levenguk (1632–1723) unicellular organisms, blood cells, spermatozoa Karl Linney (1707–1778) Coined the term “species”. Established a modern taxonomy. Created his own classification of plants and animals. Entered the Latin names of species, genera (binary nomenclature). Described over 7500 plant species and about 4000 animal species.

6. The creation of cellular theory and the development of evolutionary ideas (19th century AD) A sharp surge in the development of biology, the struggle of materialistic and idealistic views on the occurrence of matter Theodor Schwann (1810–1882) One of the authors of cellular theory (Schleiden and Virchow) Jean- Baptiste Lamarck (1744–1829) Author of the first evolutionary doctrine Charles Darwin (1809–1882) Author of the first evolutionary theory Ernst Haeckel (1834–1919) Coined the term “ecology”. Laid the foundations of phylogeny

7. The “genetic” period (since 1900) The prevalence of materialistic views, the discovery of the laws of heredity and variability of Hugo de Vries (1848–1935) The term “mutation” Karl Correns (1864–1933) Secondly discovered and confirmed the laws of Mendel by William Betson (1861– 1926) The term “genetics” (1908) Thomas Hunt Morgan Chromosome theory of heredity Watson and Crick DNA structure (1953) Gregor Mendel (1822–1884)

Definition of the concept of “life” LIFE Aristotle: “Nutrition, growth and aging” Treviranus: “The uniformity of processes with the difference of external influences” Modern understanding: “A special way of the existence of organisms, the important factors of which are metabolism with the environment and self-reproduction” ... this is the process of reproduction and evolution, occurring due to the ability to remember acquired attributes. The modern definition: “This is a special form of motion of matter, qualitatively higher than the physical and chemical forms, ele mental form of existence of a species and unit of evolution ”... these are living bodies existing on Earth, which are open self-regulating systems built from biopolymers of proteins and nucleic acids. Engels: “Life is a way of existence of protein bodies ...” Pavlov: “A complex chemical process”

Properties of the living unity of the chemical composition. The cell structure. Discreteness and integrity. A single principle of structural organization. Nutrition, respiration, excretion Metabolism and energy. Self-reproduction. Self renewal. Self-regulation Heredity and variability. Growth and development. Irritability and movement. Adaptability Rhythm

Levels of organization of living matter Molecular Cellular Organizational Population-specific Biogeocenotic Biosphere Border between living and nonliving (molecules, atoms) Cell - structural unit of living organisms Level - unit of evolution System "living organisms + abiotic factors" All living organisms of the planet and their environment

Ciliates GENERAL SIGNS: They have two nuclei, two contractile vacuoles, digestive vacuoles, and have special purpose organoids - cell mouth, pharynx, powder. Cilia movement. Propagate asexually and sexually.

Infusoria - slipper Infusoria Colony infusoria corkhesium Infusoria - trumpeter

Ciliates. The shape of the body is constant due to the elastic and durable shell - the pellicle. Actively move with the help of cilia. Another important feature is the presence of two nuclei: a large polyploid vegetative nucleus, the macronucleus, and a small diploid generative nucleus, the micronucleus. In the ectoplasm of many ciliates are special protective devices - trichocysts. When the animal is irritated, they shoot a long elastic thread that paralyzes the prey. 7,5 thousand species

The value of the simplest in nature and human life In nature, they are a link in food chains. Perform the role of orderlies, cleansing water from bacteria and rotting substances. Water purity indicators. Shells formed sedimentary rocks. Participate in the cycle of substances and in the formation of soil.

Material abstract

Biology Presentations, which can be downloaded for free from this section, offer great opportunities in the professional activity of a teacher teaching his subject creatively. The use of electronic visual aids makes the lesson interesting and understandable for students of any class. Students, thanks to the presence of a presentation on the topic of the biology lesson, not only listen to new material, but also take a direct part in its discussion, which contributes to a more productive assimilation of the subject.

Correctly designed biological presentations, which the teacher is invited to download to the lessons, are the best help in the presentation of material to students. Using multimedia developments from the World of Biology series allows you to solve several important problems in the lesson:

Increase the motivation of middle-level students in the study of the subject
Stimulate their cognitive activity
Make the presentation of material visual-figurative

You can download the presentation on the topic of general biology and microbiology:

To explain a new topic
For extracurricular activities
To organize student knowledge testing
For open lessons

It is impossible to teach a child if he is not interested and bored in the lesson. The use of presentations, interactive teaching methods, and ICT in a general biology lesson contributes to the development of student interest in the topic. Children in any class enjoy watching slides, they like it when there is animation. Of great interest are video stories from the world of biology, which demonstrate the work of the body, individual organs, the life of plants and animals is presented. Only such lessons for students are remembered for a long time.

We suggest going to sections by classes and download free biology presentationsSonina, Pasechnik and other authors, development in microbiology. All works are presented by teachers who love to teach their subject and keep up to date, using presentations for biology lessons.

Biology - Grade 5

Presentations on biology for the 5th grade will make an interesting lesson for those children who will study a new subject under the program of a five-year training cycle. The authors of the work program are Ponomareva, Karnilova and others. All topics of the manual correspond to the requirements of the Federal State Educational Standard, so the teacher going to the lesson in grade 5, it remains to find a way how ...

Biology - Grade 6

Presentations on biology for grade 6 are excellent material that will help to interestingly present the topics of lessons to students. Not only dry words about living beings and natural phenomena should be heard by children in order to understand the world around them. Fill the lessons with pictures, photographs, videos of processes taking place in nature, and each student will be able to look at this ...

Biology - Grade 7

Presentations on biology in the 7th grade in recent years have become increasingly popular among teachers in all schools, where it is possible to use computer equipment in the lessons. Scientists have recognized and proved that the use of multimedia electronic manuals increases the level of training in the subject, develops students' interest in studying new topics, makes them ...

Biology - Grade 8

Presentations on biology in the 8th grade became a compulsory visual aid to accompany each lesson. Studying the structure of the human body, the functions of individual organs and entire systems, a visual representation of what is discussed in the training session is necessary. It is impossible to explain with wisdom the structure of each department. Even having a lot of visual aids in the office ...

Biology - Grade 9

Presentations for biology lessons in grade 9 will help the teacher interest students in difficult topics that will have to be studied throughout the school year. This is the material that helps the teacher to speak in a clear language with the children. Someone is tired of repeating that modern students do not want to devote enough time to studying school subjects. Believe me, this is completely ...

Biology is a fascinating science, thanks to which students can learn the structure of surrounding organisms and their own body, realize the very concept of the word "life". But far from always useful becomes interesting. Our presentations on biology will help to interestingly and fascinatingly talk about those topics that would be much more inaccessible with a simple reading from a textbook. From amoebas to ecosystems - all presentations will help you better understand the world around you.

Biology presentations were made in PowerPoint, here you will find a large assortment of biology presentations, which can be downloaded absolutely free. To do this, just select the desired presentation and click on the "download" button. It is also possible to view all the contents of the selected work, view each slide to decide whether it suits you. Thanks to a convenient search on all presentations, you can easily find the topic you are interested in.

Biology is a subject that requires great clarity when studying a particular topic: children need to show circulatory patterns, the location of organs, the appearance of a particular animal or plant. In the "pre-computer" era, printed posters and filmstrips were of great help to teachers, but today we cannot imagine our work without MS Office PowerPoint presentations or multimedia textbook applications.

Biology lessons using presentations become “lively”, vibrant, interesting. According to teachers, children's performance is increased when using good visibility, children go on with pleasure.

Ways to use biology presentations?

At the beginning of the lesson to repeat the topic of the previous lesson or to report the topic and purpose and objectives of the new lesson. For example, presentation simulators.
As part of a lesson gaining new knowledge to demonstrate the studied material (tables, diagrams, photographs, videos, etc.). As a rule, ordinary linear presentations are used, the main purpose of which is to provide information.
As an independent lesson (e.g. generalization lesson): game lessons, debates, etc. It uses presentation-games "Own game", "Who wants to become an excellent student" and others.
To conduct a surveyor student testing. Presentation tests.

Online

On our site more than 250 author presentations on biology are presented, which are available for download for free and without registration. Presentations cover almost all sections of school biology and ecology: fish, birds, mammals, humans, mollusks, bacteria and fungi, etc.

Presentations are made taking into account age-specific features: a presentation for the 5th grade is unlikely to be interesting to high school students, and vice versa: a presentation for students in grades 10-11 will seem too complicated and incomprehensible for students in grade 7.
