Levels of Organization Review

Molecular Levels of Organization Subatomic particles (Protons, Neutrons, and Elections) Atom (oxygen, hydrogen, potassium and gold) Molecule (water and salt) Macromolecule (Proteins and carbohydrate) Organelle (Cell membrane and ribosome) Cell (skin cell, nerve cell, and liver cell)

Subatomic Particle Fundamental unit of energy and matter. Protons Neutrons Electrons The particles make up atoms.

Atom Smallest unit of matter that still has distinct chemical properties. Any element on the periodic table. Oxygen Hydrogen Sodium Potassium

molecule Two or more atoms bonded together. H2O Water NaCl Salt HCl Sodium Chloride

Macromolecule Large organic compounds that make up our organelles and cells. Lipids Nucleic Acids Carbohydrates Proteins

Organelle Structures that preform specialized function for the cell. Nucleus Cell Membrane Mitochondria

Cell The simplest entity that has all the properties of life. Skin Cell Bacteria Cell

How does structure lead to the function of the Molecular hierarchy? It is important to know that all macromolecule are built using Carbon atoms. Thus these multi-carbon molecules are used as the building blocks of organelles and cells. Lipids are important to the cell membrane, carbohydrates, storage of sugar and energy, proteins are important to the functioning of the cell, nucleic acids are important to the control of everything in the cell.

Cellular Levels of Organization Organelles (Mitochondria, Golgi, and Chloroplast ) Cells (Brain cell, skin cell, and liver cell) Tissue (Connective Tissue, Muscle tissue, Epithelia tissue) Organ (Heart, stomach, liver, and lungs) Organ System (Respiratory system and digestive system) Organism (Human, wolf, and fish)

Organelle Structures that preform specialized function for the cell. Nucleus Cell Membrane Mitochondria

Cell The simplest entity that has all the properties of life. Skin Cell Bacteria Cell

Tissue Cells of the same specialization working together to achieve a common function. Smooth muscle tissue Cardiac muscle tissue Skeletal muscle tissue

Organ Organs are made up of different tissue that work together to do a job. Heart Lungs Kindneys

Organ system Organs that work together

Organism Sum of all cells, tissues, organs and organ systems makes an organism. May be a single cell

How does structure lead to the function of the Biological hierarchy? Organism are made of many different organ systems. These organ systems are composed of organs that have a common or relevant goal. Organs are made of different specialized tissue, which are in turn built from specialized cells. These cells have a cellular/organelle make up that aids in its function. Muscle cells have more mitochondria Pancreatic cells have more Rough ERs and Golgi https://www.youtube.com/watch?v=TeZHenI6Z7s

Ecological levels of Organization Organism (bird, grass, tree, squirrel) Population (group of birds) Community (Birds and squirrel populations) Ecosystem (Birds, squirrel, sun, wind, trees, rain) Biome (Rainforest and artic tundra) Biosphere (earth)

Organism Sum of all cells, tissues, organs and organ systems makes an organism. May be a single cell

Population Same type of organism living together in the same place

Community Several populations living together Populations interact

Ecosystem A biotic (living) community plus the abiotic (nonliving) features Birds, wind, trees, rain, worms, sunlight

Biome Similar ecosystems on earth together

Biosphere Entire worlds living and nonliving factors

How does structure lead to the function of the Ecological Hierarchy? This video shows why the ecological hierarchy is so important and what happens when a component of the levels of organization are removed and how this goes on the effect the functioning of the rest of the levels of organization. How Wolves Changed Rivers (Wolves of Yellowstone) https://www.youtube.com/watch?v=ysa5OBhXz-Q The gist of it? All organism and even abiotic factors rely in some way or another on different organism in an ecosystem.
