Task 3

Topic: Common features of living organisms / Diversity of organisms (for example

plants and animals)

The exchange of matter and energy with the environment, due to which the constancy of the internal environment of the body (homeostasis) is maintained.

Irritability is the body’s ability to selectively respond to external influences.

Reproduction or Self -Reproduction – the ability of an organism to produce offspring, which, due to heredity, is similar to the parent. The ability of organisms to increase in numbers.

Ability to evolve : due to variability, children are not born as complete copies of their parents, and there are too many of these children, there are not enough resources for everyone, so the fittest survive.

Generality of chemical composition . The main features of the chemical composition of a cell and a multicellular organism are carbon compounds – proteins, fats, carbohydrates, nucleic acids. In inanimate nature, these compounds are not formed.

Self -regulation – maintaining the constancy of the internal environment of the body (homeostasis). Persistent violation of homeostasis leads to the death of the body.

Irritability – the body’s ability to respond to external and internal stimuli (reflexes in animals and tropisms, taxises and nastia in plants).

Variability – the ability of organisms to acquire new features and properties as a result of the influence of the external environment and changes in the hereditary apparatus – DNA molecules.

Heredity is the ability of an organism to pass on its traits from generation to generation.

Growth – the ability of living organisms to change their size during life

Development – individual development of the organism, transformations, the emergence of new structures
