Question 1. How do plants differ from animals?
Question 2. What signs are characteristic of living organisms?
Living organisms grow, eat, breathe, develop, reproduce, have irritability, and release products of their vital activity (metabolism and energy) into their environment. All living organisms are made up of cells (except viruses).
Question 1. What kingdoms of living organisms do you know?
There are four kingdoms: Bacteria, Fungi, Plants and Animals.
Question 2. What features distinguish living organisms from inanimate objects?
Living organisms differ from inanimate objects in the following features: growth, nutrition, respiration, development, reproduction, irritability, excretion, metabolism and energy, mobility. Inanimate objects do not have such features.
Question 3. What is the importance of the ability of organisms to reproduce for the existence of life on Earth?
If reproduction stops at any stage of organisms, all living things will gradually disappear. This speaks about the interconnection of living organisms. Reproduction carries out the transmission of hereditary information and the continuity of generations. Reproduction allows a population to exist, to continue its species.
Think
Consider Figure 9. What phenomenon is depicted in it and why is it called the “power circuit”? Make up your own food chain, characteristic of living organisms living in your area.
This figure depicts the "power circuit" phenomenon. It really looks like a chain of certain links that successively replace each other. Examples:
Sun →grass →hare →wolf;
Sun → tree foliage → caterpillar → bird (tit, oriole) → hawk or falcon;
Spruce → squirrel → marten;
Sun →grass →caterpillar →mouse →viper →hedgehog →fox.

The earth is inhabited by diverse living creatures that are not similar to each other. Despite their different structure and special way of life, they are united by the properties of living organisms. These properties distinguish living matter (all living creatures on the planet) from inanimate nature (mountains, rivers, stones).
Properties
The differences between living nature and inanimate matter are described in detail in the table of properties of a living organism.

Description |
Cellular structure |
Living things are made up of cells - the “building blocks of life”. This is the unit of all living things. Life is impossible outside a cell |
The energy necessary to maintain life is extracted from food. Plants are autotrophs and use sunlight, carbon dioxide, and water with minerals as food. The process of creating nutrients inside the body using light is called photosynthesis. The rest of the creatures feed on ready-made substances, i.e. eat other creatures and are called heterotrophs |
|
Metabolism |
The scientific name is metabolism. It is the process of extracting useful, nutritious, vital substances from food that comes from external environment. Complex substances break down into simpler ones, from which each cell forms the substances necessary for the body, and also extracts energy and heat. |
It is part of metabolism. Organisms absorb oxygen from the air and release carbon dioxide. Oxygen oxidizes, i.e. combines with other substances and participates in complex biochemical reactions |
|
Organisms are constantly growing. In multicellular organisms this occurs due to cell division |
|
Irritability |
The ability to respond to manifestations of the external environment. For example, flowers close when there is a lack of sunlight, and a person withdraws his hand when it comes into contact with a hot object |
Reproduction |
Organisms reproduce creatures similar to themselves. This is a complex process that can occur in different ways depending on the complexity of the organization of the body. For example, single-celled creatures divide, plants reproduce by seeds or parts of the body, for the reproduction of mammals two individuals are needed - male and female |
This natural process is the logical conclusion of life. All living beings, regardless of life expectancy, die and decompose, giving food to other organisms |
Rice. 1. Cellular structure of organisms.
Living organisms do not live separately from inanimate nature, but actively interact with it. Water and oxygen are nonliving matter, but they are vital substances for living organisms. The interaction of living and nonliving nature through metabolism is called the cycle of substances.
Biological diversity
The general properties of living things are inherent in both unicellular organisms, consisting of just one cell, and complexly organized animals, such as humans. All biological diversity for ease of study divided into five kingdoms:
- viruses;
- bacteria;
- plants;
- mushrooms;
- animals.
Rice. 2. Kingdoms of living nature.
Many scientists attribute viruses to inanimate nature. They are on the border of the transition of substances into living form and have the properties of living and nonliving matter. For example, they are capable of reproduction, but do not grow or feed.
Bacteria are different from others single-celled organisms(plants and animals) by the absence of a nucleus - the part of the cell in which hereditary information is stored. Such primitive organisms reproduce by division and have all the signs of life.
TOP 4 articleswho are reading along with this
Plants, fungi and animals are eukaryotes. Their cells have a formed nucleus. Plants differ from fungi in the presence of leaves and the ability to photosynthesize. Mushrooms are not animals, because... They have a special structure and are not capable of active movement.
The animal kingdom is very vast and covers many creatures from single-celled protozoa (amoeba) to mammals (elephant, cat, squirrel), which includes humans.
Rice. 3. Diversity of animals.
All living organisms have the same chemical composition, because... consist of the same elements. Carbon, oxygen, nitrogen, and hydrogen are important for life.
What have we learned?
From the 5th grade biology lesson we learned about the basic properties of living matter, as well as the diversity of life on Earth. The main signs of living things are reproduction, respiration, nutrition, growth. The basis of all living beings is the cell. The entire diversity of living nature is represented by five kingdoms - viruses, bacteria, plants, fungi, animals. Viruses are a transitional form from nonliving to living matter.

Information sheet |
Basic terms and concepts tested in exam paper : homeostasis, unity of living and inanimate nature, variability, heredity, metabolism.
– cellular structure . All organisms existing on Earth are made up of cells. The exception is viruses, which exhibit living properties only in other organisms.
Metabolism – a set of biochemical transformations occurring in the body and other biosystems.
Self-regulation – maintaining a constant internal environment of the body (homeostasis). Persistent disruption of homeostasis leads to the death of the organism.
Irritability – the body’s ability to respond to external and internal stimuli (reflexes in animals and tropisms, taxis and nasties in plants).
Variability – the ability of organisms to acquire new characteristics and properties as a result of the influence of the external environment and changes in the hereditary apparatus – DNA molecules.
Heredity – the ability of an organism to transmit its characteristics from generation to generation.
Reproduction or self-reproduction – the ability of living systems to reproduce their own kind. Reproduction is based on the process of doubling DNA molecules followed by cell division.
Growth and development – all organisms grow during their lives; Development is understood as both the individual development of an organism and the historical development of living nature.
System openness – a property of all living systems associated with the constant supply of energy from the outside and the removal of waste products. In other words, the organism is alive as long as it exchanges substances and energy with the environment.
Ability to adapt - in progress historical development and under the influence natural selection organisms acquire adaptations to conditions environment(adaptations). Organisms that do not have the necessary adaptations die out.
Community chemical composition . The main features of the chemical composition of a cell and a multicellular organism are carbon compounds - proteins, fats, carbohydrates, nucleic acids. These compounds are not formed in inanimate nature.
The commonality of the chemical composition of living systems and inanimate nature speaks of the unity and connection of living and inanimate matter. The whole world is a system based on individual atoms. Atoms interact with each other to form molecules. Rock crystals, stars, planets, and the universe are formed from molecules in nonliving systems. From the molecules that make up organisms, living systems are formed - cells, tissues, organisms. The interrelation of living and nonliving systems is clearly manifested at the level of biogeocenoses and the biosphere.
Main levels of organization of living nature: cellular, organismal, population-species, biogeocenotic
Basic terms and concepts tested in exam papers: standard of living, biological systems studied at this level, molecular genetic, cellular, organismal, population-species, biogeocenotic, biosphere.
Levels of organization living systems reflect the subordination and hierarchy of the structural organization of life. Levels of life differ from each other in the complexity of the organization of the system. A cell is simpler compared to a multicellular organism or population.
The standard of living is the form and method of its existence. For example, a virus exists in the form of a DNA or RNA molecule enclosed in a protein shell. This is the form of existence of the virus. However, the virus exhibits the properties of a living system only when it enters the cell of another organism. There it reproduces. This is his way of existence.
Molecular genetic level represented by individual biopolymers (DNA, RNA, proteins, lipids, carbohydrates and other compounds); at this level of life, phenomena related to changes (mutations) and reproduction are studied genetic material, metabolism.
Cellular - the level at which life exists in the form of a cell - the structural and functional unit of life. At this level, processes such as metabolism and energy, information exchange, reproduction, photosynthesis, nerve impulse transmission and many others are studied.
Organismal - this is the independent existence of an individual - a unicellular or multicellular organism.
Population-species – level, which is represented by a group of individuals of the same species – a population; It is in the population that elementary evolutionary processes take place - the accumulation, manifestation and selection of mutations.
Biogeocenotic – represented by ecosystems consisting of different populations and their habitats.
Biosphere – a level representing the totality of all biogeocenoses. In the biosphere there is a circulation of substances and the transformation of energy with the participation of organisms. The waste products of organisms participate in the process of evolution of the Earth.
