Levels of Biological Organization

Biological Organization

Organ System

Organelle

Tissue

Molecules are atoms that are held together by chemical bonds.

In the quote "The whole is greter than the sum of its parts" is very true and can be easily applied and it is espically true for biological orginzation. If you don't add up all of those parts you only have a bunch of atoms, and that is no use. If you start putting all of those parts together you have something. When you add them together you know have molecules, when you put those together you have macromoelecules and when you combine those and you have a cell. If you just keep adding these up you have an organism and that is so much more useful than just a bunch of atoms. For example if you have a bunch of walls, their is no use for that, but if you put them together you have rooms and it is much more useful because it can be used for shelter. If you put all of those rooms together you have a house, and a house is much more useful than a bunch of rooms. The quote stated above is true and can be applied to biological organization.

An organ system is a system made up of multiple different organs that work together to preform a job for that organism. When you combine the brain with other organs you get the nervous system, as seen in the picture, this makes it the eighth level of biological organization, because the nervous system is made up of many organs and the eith level is the organ system.

Organelles are the different parts of the eukaryotic cell, each of them have a specific function. An example of an organelle would be the mitochondria, it is made up of many macromolecules, this makes it the fourth level of biological organization. This picture shows all of the organelle that make up a eukaryotic cell.

When many cells are put together, tissue is made. Tissue is a material that serves a specific function in an organism. This is a picture of brain tissue it is made up of many cells, making it the sixth level of organization

The biological level of organization is organized by living things from simplest to most complex. Every organism has a very similar biological organization and it shows what we are designed of.

• Atoms
• Molecule
• Macromolecules
• Organelle
• Cell
• Tissue
• Organ System
• Organism
• For example a molecule is made up of atoms and then macromolecules are made of molecules and so on.

This picture is a molecule, it is made up of atoms. This is the second level of biological organization because it is a molecule and that is what the second level of biological organization is.

Atom

Cell

Macromolecule

Organism

An atom is the smallest part of the element. It has neutrons, protons and electrons, each atom varies the number of protons, neutrons and electrons depending on the element it is

Organ

A macromolecule is a complex molecule, it is made up of hundred or thousand of atoms, unlike a molecule that is just made up of several. The picture shows a macromolecule, which is made up of many molecules, and those are made up of atoms, this is the third level of biological organization.

An organism is any form of life, composed of cells that work together to sustain life. Examples of organisms are plants, animals and bacteria. This picture shows a human which is an example of an orgainism. When you put all of the organ systems together you create an orgainism, making this the ninth level of biological orginazation.

When you combine many organelles you get a cell, this makes it the fifth level of biological organization. A cell is the basic unit of all living things. This picture is a cell made up of many organelles.

An organ is a group of tissue that is put together to preform a specified tasks. This picture is a brain, when you put all the brain tissue together you get a brain, this makes it the seventh level of biological organization.

The first level of biological organization is an atom, this is an example of an atom.
