The living beings that surround us are classified into five kingdoms: animal, plant,monera, protista and fungi.
This classification is based on the mode of nutrition of each living being, which may beheterotrophic, if it feeds on other living beings, or autotrophic, if it produces its own food from inorganic material. This division is also based on the number of cells that it has, that is, whether it is monocellular and formed from a single cell, or multicellular, and composed of various cells.
2.1The animal kingdom
Animals are multicellular living beings that feed on other living beings. This means that their nutrition is heterotrophic.
They can move, which enables them to obtain food, hunt and defend themselves, among other things.
They have sense organs, which enable them to interact with the world around them, and a nervous system which, depending on the type of animal, can have different levels of complexity.
Depending on whether or not they have a vertebral column, they are classified asvertebrates or invertebrates:
- Vertebrates have a vertebral column. They are more complex and are divided into five groups: fish, amphibians, reptiles, birds and mammals. Human beings belong to the mammals group.
- Invertebrates have no vertebral column. They are less complex than vertebrates, but are also more numerous. They are divided into many groups, which include: porifera (sponges), cnidaria (jelly fish), worms (earthworm), echinoderms (starfish), molluscs (muscle) and arthropods (spider).
2.2The Plant Kingdom
The plant kingdom consists of multicellular, autotrophic living beings, which means they produce their own food.
Through a process called photosynthesis, plants transform water and mineral salts that they absorb through their roots from the soil and carbon dioxide that they receive through their leaves into nutrients. They perform this transformation with the help of light from the Sun.
In contrast to animals, they cannot move around, since they are normally fixed to the soil.
Plants can reproduce sexually or asexually. Plants with flowers reproduce sexually. A fruit, which contains seeds, is generated through the flower. These can germinate to give rise to a new plant. Plants that reproduce asexually, do this through spores orcuttings, for example. No type of seed is involved in asexual reproduction.
2.3The fungi kingdom
The fungi kingdom consists of heterotrophic living beings, which may bemonocellular or multicellular.
Although some are similar to plants, they do not produce their own food, instead, they feed on other living beings or their remains.
Examples of monocellular fungi include yeast. Examples multicellular fungi include mould and mushrooms.
Yeast is a fungus formed by an oval cell. It is found in very diverse environments. Some types of yeast use the sugar in foods to obtain energy to feed themselves, in a process called fermentation. During this process, the characteristics of the food, such as its smell, taste or texture may change. Human beings take advantage of this property of yeast to transform certain foods into others, such as flour into bread, must into wine and barley into beer.
Moulds and mushrooms are also multicellular fungi. They consist of a network of threads called hyphae, which weave together to form the mycelium. These threads are found underground and absorb the food that the fungi need to live. When the rainy season starts, the mycelium cause the mushrooms to appear at the surface of the earth. The mushroom is not the entire fungus, but instead, its reproductive part, which contains spores. Therefore, its reproduction is asexual. These structures live in very damp environments and feed on the organic material of the soil. They appear in autumn, when there is more rain and there are more leaves decomposing in the soil, which are their source of food.
Mould is a type of fungus that grows on food that is going bad. It reproduces asexuallythrough cells called spores, which move towards other foods and develop new mould.
2.4The monera kingdom
The monera kingdom is formed by monocellular organisms, which means that they are made of a single cell. Furthermore, this cell is simpler than the ones in plants and animals because it has no nucleus.
The organisms that make up this kingdom are the smallest living beings in existence, which means that they can be seen only through a microscope.
This kingdom includes bacteria and cyanobacteria.
A microscope is an apparatus used to observe very small or microscopic elements, such as cells, viruses and living beings, such as bacteria.
Bacteria are the best-known monera. They may be autotrophic or heterotrophic, which means, they may feed on inorganic material or other living beings.
They reproduce through binary fission, through which an initial bacteria divides into two and forms identical daughter cells, which can also divide. These cells can have different shapes.
Bacteria can live in all mediums: air, water and soil. They can even live in the body of living beings, both inside and on the skin, where they can find nourishment.
Bacteria are well-known because they can give us diseases, such as gastroenteritis, but we should also remember that many bacteria are beneficial to living beings. For example, bacteria such as lactobacillus are used to produce cheeses and yoghurt from milk, through a process called fermentation.
Inside our bodies and in those of other animals there are bacteria such as escherichia coli, which are found in our intestines and which help us to digest food.
Antibiotics are medicines that can eliminate disease-causing bacteria However, not all diseases are caused by bacteria, and not all of them can be eliminated through antibiotics.
Cyanobacteria were the first monera in existence. In the past they were known as blue-green algae. They are autotrophs, which means they use inorganic material and light from the Sun to perform photosynthesis, a process that allows them to obtain nutrients and whose end product is oxygen. Oxygen is a gas that forms part of the air and which other living beings use to respire.
When the planet was formed, there was no oxygen in its atmosphere and living beings did not exist. When cyanobacteria appeared, they began producing oxygen, which enabled all other living beings to develop.
Viruses are not living beings because they cannot find nourishment or reproduce alone, instead, they need to be inside other cells in order to do this.
They can infect animal, vegetable, fungal and protistan cells, including bacteria. Viruses that infect bacteria are called bacteriophages.
All viruses cause diseases, but they can be used to create vaccines against themselves.
2.5The protista kingdom
The protista kingdom consists of living beings that differ from each other enormously. They may be autotrophs or heterotrophs, monocellular or multicellular.
The protista kingdom includes protozoa and algae.
Protozoa are monocellular living beings, which means they are formed from a single cell, so they can be seen only through a microscope. They live in water or in damp soil, although some of them are parasites, which reside inside living beings and cause them to get ill. They may reproduce sexually or asexually.
They feed on organic material, which can be found in the environment and on other living beings, such as monocellular bacteria and algae, which means they areheterotrophs. They are able to move because certain parts of their body have mobility.
Amoeba and paramecia are protozoa.
Algae are organisms that live in water, both fresh and salt water. They are not found in very deep areas, since they need light from the Sun to live. As a result of their pigmentation, they can receive light and perform photosynthesis using inorganic material, which means that their nutrition is autotrophic.
You can find algae in different colours: green, red and brown.
Algae may be monocellular or multicellular, and reproduce sexually or asexually.

2.LIVING THINGS: Internal Structure
All living things are form by cells.
CELLS are the basic units of life. They are microscopic and they are alive (they carry out the nutrition, interaction and reproduction).
Living things can have:
- 1 cell: unicellular organisms
- more than 1 cell: multicellular organisms
