Level of Life Organization: Sequence, Structure, & Understanding FULLDilihat: kali
Level of Life Organization – material order of organization of life and this understanding will make us better understand and know the benefits of biology. We will also increasingly aware, not overbearing, and give thanks to God who has created us. Because the true man is a weak creature composed of cells, tissues, organs, and so on, all of which will not work when one section having problems (pain).
Other living beings are also given the completeness of organs that are not much different from us humans, there are hands, feet, eyes, ears, and other organs. But only a human being was given intellect of the most high over all other living creatures. Therefore, let’s raise our gratitude to study biology and familiar with the parts of our lives, from the smallest to the greatest extent. This is the level of Life Organization.
Level of Life Organization
Before the continued discussion of this matter, do not forget also the branch of biology that has been described in the previous material, to always remember, then apply the understanding at the organizational level following the life of this because there are also related, in order to better understand and not just memorized. Remember, biology is not rote, but better implementation (applied).
Generally we have known only the smallest part of a living thing is a cell, padalah inside the cell there is still a component or constituent smaller again. Is that? The following explanation will further clarify your curiosity.
Sequence Levels of Life Organization
What’s the molecule? what is a network? and what it komunisat? Okay, let’s discuss one by one starting from the organization of life from the lowest to highest.
1. Molecular Level
While studying chemistry, we might already know that the lowest level of the material are protons, neutrons, and electrons. Particles of protons, neutrons, and electrons combine to form atoms (eg hydrogen, carbon, nitrogen, and oxygen). The atoms then bind to form molecules, such as water molecules, glucose, proteins, and DNA. Yes, DNA is the molecule.
These molecules bind to each other and form a bond more complex organelles in the cell constituent. Therefore, it can be said that the molecules, atoms, and subatomic particles constitute the functional organization of the biochemical level (chemical compounds making up living beings).
2. Level Cell
Various kinds of molecules bind to each other to form organelles. Organelles is component (subunit) cells with specific functions, such as the ribosome where protein synthesis. Protein synthesis is the process of preparing the protein. Various compounds and organelles interact with each other to form a unity called cells.
A single cell has the characteristics of living things. Each cell has a matter of heredity, metabolic activity, is able to grow and thrive. Because it has the characteristics required as a living being, the cell referred to as the smallest unit of life. Cell size is so small that it takes a microscope to see it.
3. Level Network
Network found in multicellular organisms (multicellular). Network is a collection of cells that has the form (structure) and the same function. The cell group has a specific function. Here are examples of tissues in living organisms.
Animal tissue composed of several types. The networks included the epithelial tissue, nerve tissue, muscle tissue, and blood tissue. Epithelial tissue composed of epithelial cells that are interconnected. Neural network consists of nerve cells that function to receive and respond to stimuli. Muscle tissue is a long fiber that has a function as a tool motion. The blood tissue composed of blood cells. These blood cells have different functions. There are circulating oxygen, nutrients, some are functioning as antibodies or immune system. More details on this matter, will be discussed in class XI.
Network on Plant
Like tissue in animals, tissues in plants (Figure 1.10b) also consists of various types. Contained in the plant tissue in between the epidermal tissue, vascular tissue, tissue reinforcement, and meristem tissue. Epidermal tissue is the tissue that coats plant surfaces. Vascular tissue consisting of xylem and phloem. Functioning xylem transports water and soil nutrients from the roots to the leaves, while the phloem transport of photo- synthesis function of leaves throughout the plant body. Network reinforcement in plants composed of cells that are thick and strong. This amplifier supports network functions plant body. The meristem tissue is active tissue divide to produce new cells. Further on the network on plant matter will be discussed in class XI.
4. Levels Organ
Organ also only found in multicellular organisms. Organ is a structure formed of several types of tissues that work together to perform certain functions. For example, neural networks and brain organ connective tissue construct and work together to carry out the coordination function. Epidermal tissue, tissue mast, and the spongy tissue of leaves and arrange organs work together to carry out the functions of photosynthesis, transpiration and gas exchange.
Examples of other organ is the heart organ whose role is to pump blood; lungs to exchange oxygen and carbon dioxide; organ ears to hear; and organs of the eye to see. Organs in plants, for example leaves for gas exchange, interest for breeding, and the roots to absorb water and mineral salts.
5. System Level Organisms
The organs that perform the functions and duties referred to as a system of interrelated organs. For example, the respiratory system formed from the same working organ of the nose, pharynx, larynx, trachea, bronchi, and lungs to function respiration. The digestive system is made up of cooperation organ of the mouth, esophagus, stomach, intestines, liver, and pancreas. Digestive system function execute digestion and absorption of food juices. Motion system to support and move the body composed of the muscular and skeletal. You mentioned the example of other organ systems as well as the name of its constituent organs.
6. Level Organisms (Individual)
Especially for single-celled organisms (unicellular), the organism has been referred to as an individual. Example: bacteria and protozoa are examples of single-celled organisms. One bacteria and protozoa one is said to be an individual. As for humans, cats, palm trees and jasmine plants are examples of multicellular organisms. A human, a cat, a coconut tree, and a sprig of jasmine plant is also said to be an individual.
Individual multicellular forms of organ-system organ systems that work together in a union. Each organ system can not perform its function on its own. Each organ system has a hanger sustainability on other organ systems. For example in humans, respiratory system, circulatory system, digestive system, flushing system, coordinate systems, motion systems, and reproductive system have a mutual dependence.
7. Level of Population
Individuals are similar (and can mate and produce offspring) who gather in a certain place at the same time establish the level of organization of life known as a population. Students who are in school named as the human population, a collection of grass that is in the school yard named populations of grass, grasshopper collection called grasshopper population, a collection of earthworms called worm population, and a collection of so-called bee bee populations
8. Community Level
Generally somewhere there is more than one population. Pay attention to your school yard. There may be a population of grass, worm population, the population of grasshoppers and ants. Set of populations that occupy the same area and are interconnected so-called community. Within the community there is always interaction, both among members of the same species, as well as the interaction of different antarpopulasi.
9. Levels Ecosystem
At the ecosystem level, many things can be learned, such as the mutual relationship antarkomponen biotic, abiotic antarkomponen mutual relations, as well as the interrelationships between biotic and abiotic components.
In organizational life ecosystem level, we can also see the flow of energy from photosynthetic organisms to herbivores and carnivores.
10. The level of biome
Greater extent as an object Biology studied are biomes. Biome is an area of land that is fairly widespread in the earth is characterized by a dominant plant species. Examples desert biome, the biome grasslands, tropical rain forest biome, biomes tundra and taiga biome. The object level Biology greatest learned is the biosphere. What is the biosphere?
Well, after understanding one by one penjelasnnya, the following organizational level scheme of life more clearly in images from lowest to highest.
