FCAT Standard #48
SC.6.L.14.1
Describe and identify patterns In the hierarchical organization of organisms from atoms to molecules and cells to tissues to organs to organ systems.
SC.6.l.14.2
Investigate and explain the components of the scientific theory of cells (cell theory): all organisms are composed of cells (single-celled or multicellular), all cells come from pre-existing cells, and cells are the basic unit of life.
Vocabulary
Atom: the basic unit of matter that makes up all objects.
Molecule: the smallest amount of chemical substance.
Cell: the basic unit of structure in living things.
Tissue: a group of cells.
Organ: a collection of tissue coming together for a common purpose.
Organ System: groups of organs working together to preform a specific body function.
Organism: any living thing.
Molecule: the smallest amount of chemical substance.
Cell: the basic unit of structure in living things.
Tissue: a group of cells.
Organ: a collection of tissue coming together for a common purpose.
Organ System: groups of organs working together to preform a specific body function.
Organism: any living thing.
The inside of organisms are organized into many levels. From smallest to largest, they go atom, molecule, cell, tissue, organ, organ system, and organism.
Atoms
Atoms are the basic units of all mater and make up everyday objects. They are the smallest unit in the organization of organism. |

Molecules
Molecules are the smallest amount of chemical substance that can exist. Atoms that stick together are called molecules. They also make up everyday objects. |
Cells
All living things are composed of cells. While some organisms are unicellular only having one cell, other multicellular organisms consist of many cells. Cells are the basic unit of structure and function because they are the smallest unit of life that can reduplicate themselves, this happens through mitosis.

Cell Theory
Cell Theory mainly says three things about cells:
1. All living things are made out of cells.
2. Cells are the basic unit of structure and function in living things.
3. All cells come from existing cells.
Cells were discovered in the 17th century by Robert Hooke. In 1838, the cell theory was born. Matthias Schleiden and Theodor Schwann are responsible for the cell theory, although other scientists contributed to the theory.

Tissue
Tissue is made up of cells. Tissues are grouped together to make up organs. There are three main types of muscle tissues which are skeletal, smooth, and cardiac. |

Organs
An organ is a collection of tissue that comes together for a common purpose. A few vital organs are the heart, brain, lungs, kidneys, and the liver. |
Organ Systems
Organ Systems are multiple organs that work together to preform a specific body function. Organ systems in the body are the Circulatory System, Digestive System, Muscular System, Nervous System, Respiratory System, Reproduction System, Skeletal System, and Excretory System. |

Organism
An organism is an animal, plant, or a unicellular life form. They are made of organ systems that make it possible to live. You are an organism!
