Organization of Life: Levels 1 and 2 Lesson 1: Organization of LifeMiKeKiM Educational Services: Biology2 The 1 st Level: The Atom The atom consists of sub-atomic particles -The Proton (P) -The Neutron (N) -The Electron (e - ) The 2 nd Level: The Molecule Atoms combine to form the second level -The term used to describe combine is bond. - In other words; Atoms will bond to other atoms to form molecules. -The water example can be explained this way; 1 Oxygen atom (the Red object) bonds to 2 Hydrogen atoms (the Blue Objects). This molecule has a total of 3 different atoms.

Organization of Life : Levels 3 and 4 Lesson 1: Organization of LifeMiKeKiM Educational Services: Biology5 The 3 rd Level: The Cell -The Simplest of living things. -This level is where Life begins. -This is where life processes occur Example: metabolism. The 4 th Level: The Tissue - A group of cells with a common function and structure. - Examples are Muscle and Nervous

Organization of Life : Levels 5 and 6 Lesson 1: Organization of LifeMiKeKiM Educational Services: Biology6 The 5 th Level: The Organ -Composed of a number of tissues -Organized for a specific task -Example: Connective and Muscle tissue combine to form the Heart The 6 th Level: Organ System - Organs combine to work together - Example: Digestive System -The human body has 11 organ systems Mouth; Esophagus; Stomach; Duodenum; Jejunum; Ileum; Colon; Rectum and Anus
