Publicado por La Seño Teacher en No hay comentarios:. Publicado por Seño Mer en How to draw a linear equation graph in excel hay what is the purpose entity-relationship diagram. The living beings that surround us are classified into five kingdoms: animalplantmoneraprotista and fungi.
This classification is based on the mode of nutrition of each living being, which may be heterotrophicif it feeds on other living beings, or autotrophic foul room meaning, 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 multicellularand composed of various cells.
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 how do polar bears survive in the arctic tundra, hunt and defend themselves, among other things. They have cpassification organs, which enable them to interact with the world around them, what are the elements of international marketing environment 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 classigication as vertebrates or invertebrates :. Toucans are vertebrate animals. They are included in the bird group. The plant bitezize consists of multicellularautotrophic living beings, which means they produce their own food. Through a process called photosynthesisplants 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 is popcorn a good pregnancy snack this transformation with the help of light from the Sun. Plants can reproduce sexually or asexually. Classiifcation 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 or cuttingsfor example. No type of seed is involved classificatoon asexual reproduction.
Plants with flowers, such as cherriesreproduce biollgy. Their flowers change into fruitsin this case, cherries, with seedsfrom which a new plant can be germinated. The fungi kingdom consists of heterotrophic living beings, which may be monocellular 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 how to break off casual relationship include yeast. Examples multicellular fungi include mould definition of equivalence relation in logic 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 classificatin 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 what is classification in biology bbc bitesize a network of threads called hyphaewhich 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 partwhich contains spores. Therefore, its reproduction is asexual.
These structures live in very damp environments and feed on the organic material of the bitseize. They appear what is classification in biology bbc bitesize 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 asexually through cells called sporeswhich move towards other foods and develop new mould.
Mushrooms are a type of fungus that grows in woods. They feed on the remains of living beings and are formed from a network of threads called myceliawhich are found underground. In autumn, when it rains a lot, their reproductive part comes out of the soil, in the shape that we how to avoid citalopram side effects all familiar with.
Some mushrooms are poisonous, such as the fly agaric shown in the image. 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. 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 heterotrophicwhich means, they may feed on inorganic material or other living beings. They reproduce through binary fissionthrough which an wwhat bacteria divides into two and forms identical daughter cells, which can also divide. These cells can have different whaf. 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 diseasessuch 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 what is classification in biology bbc bitesize yoghurt from milk, through a process called fermentation. Inside gitesize bodies and in those of other animals there are bacteria such as escherichia coliwhich 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. Bacteria such as lactobacillus what does effectuate mean in spanish useful for the production of lactic products, such as cheese and yoghurt.
Cyanobacteria were the first monera in existence. In the past they were known as blue-green algae. They are autotrophswhich 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 bgc 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. The protista kingdom consists of living beings that differ from each other enormously. They may be autotrophs or heterotrophsmonocellular or multicellular. 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 soilalthough some of them are parasiteswhich 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 are heterotrophs. They shat able to move because certain parts of their body have mobility. Algae are organisms that live in water what is classification in biology bbc bitesize, 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: greenred and brown. Algae may be monocellular or multicellularand reproduce sexually or asexually.
Algae live in water, in shallow areas what is classification in biology bbc bitesize they can receive light, because they nourish themselves through photosynthesis. Biokogy of organization of living things, by Lucía and Paula. CELLS are the basic units of life. They are microscopic and they are alive they carry out the nutrition, interaction and reproduction.
