WHAT IS A BIOLOGICAL PHENOMENON? 20 EXAMPLES - BIOLOGY - 2025

The biological phenomena are processes performed by living things to reproduce, nourished, breathe, interact and survive general. They are any type of change that alters the life of ecosystems, biological dependencies and trophic systems of ecosystems. For example, photosynthesis is a biological phenomenon in which plants acquire their own nutrients from water, carbon dioxide, and sunlight.

Biological phenomena are usually chained by a series of chemical reactions or other events that result in a transformation. These are regulated by many means such as gene expression, protein modification, etc.

Examples of biological phenomena

Photosynthesis

This is the most important biological phenomenon that occurs on earth. Plants through photosynthesis get the necessary nutrients to grow and maintain themselves.

This supports the foundations of the food chain since animals live on plants, carnivores and humans live on plants and other smaller animals, and decomposing organisms are responsible for returning nutrients to the soil so that they plants can produce photosynthesis.

In addition to making their own food, they clean CO2 from the atmosphere.

Cell adhesion

It is the ability of cells to bind to elements of the external environment or other cells.

It is produced by electrostatic forces in addition to specific cell adhesion molecules

Morphogenesis

It is the biological phenomenon by which a living being develops its form. This process organizes embryonic cells to create a new being.

It can also happen in adult bodies such as the growth of a tumor.

Pigmentation

The biological phenomenon by which certain cells acquire color, such as the green cells of plants, or the red cells of the blood. It is a coloration that is produced by the existence of pigments

Reproduction

Sexual reproduction

It is the biological phenomenon by which new organisms can be created. It can be of two types, sexual or asexual reproduction.

Sexual reproduction is based on the interaction of chromosomes by the two parents, which will grant common characteristics to their descendants.

On the other hand, asexual reproduction is one that takes place in cells that have fungal division, and can separate or create a new one.

Unlike sexual reproduction, in this the characteristics of the new body produced will be the same as those of the parents.

Digestion

This biological phenomenon is the process by which a living being transforms previously digested food into essential nutrients for the body.

The digestive system is very important for heterotrophs, as it is necessary for the maintenance of life.

Fermentation

Fermentation is the biological process by which some types of fungi breathe. Anaerobic respiration consists of the extraction of energy from a substance, used to oxidize glucose and thus adenosine triphosphate, also known as adenosine phosphate, is obtained.

Yeasts also have a certain type of fermentation, which is known as alcoholic fermentation. By breaking down glucose molecules for energy, ethanol is produced.

Fertilization

After reproduction, fertilization comes. This biological process occurs when an egg is fertilized by sperm.

The two cells unite to form a new life, which will share the genes of both parents.

Germination

This is the biological process by which an embryo develops into a small root that can become a tree or plant.

Tropism

This biological phenomenon occurs when an environmental stimulus normally causes a plant to change direction.

If the organ moves in the same direction as the stimulus, it is called positive tropism. If it moves away from the stimulus, it is the negative tropism.

Hybridization

This biological phenomenon occurs when two living beings of different class or sub-race intersect, causing a new one with characteristics of both.

Hybrids generally lose their reproductive capacity and cannot create a new species naturally

Metamorphosis

This is the biological process by which a living being changes major physical features throughout its life.

For example, the butterfly is born as a larva, turns into a cocoon, and then ends up as a butterfly. They are notable morphological changes in the body of living beings.

Perspiration

It is the biological phenomenon by which living beings evaporate the water they have inside through the pores of their skin.

It is a physiological process controlled directly by the nervous system. Although there are some animals that have an internal regulation system that prevents them from perspiring by adjusting their body temperature

Secretion

It is the biological phenomenon by which the cell or living being expels waste from its body. In multicellular organisms, the secretion is carried out through glands.

And in larger animals, there is an internal environment that is responsible for endocrine secretions.

Cell differentiation

Cell differentiation is the process by which the cells of a specific cell lineage modify their gene expression, to acquire the morphology and functions of a specific cell type that is different from the rest of the cell types in the body.

Any cell that has that power is what is called a stem cell.

Cell growth

All living organisms have the cell as a fundamental unit of function and structure, it develops only from a pre-existing cell and later the generated cell has a life of its own

Breathing

Gas exchange in the respiratory organs of vertebrates. Necessary for the oxidation of nutrients and their transformation into energy.

There are two types, the external one, which is the exchange of oxygen and carbon dioxide, and the internal one, which is the exchange of gases at the cellular level.

Red tide

It is a phenomenon that occurs in the sea due to the proliferation of millions of tiny algae that give it a reddish color.
