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.

Services: Biology3 The Atom In the following examples identify the
number of: Protons P; Neutrons N and Electrons e - Protons = 6
Neutrons = 6 Electrons = 6 Protons = 7 Neutrons = 7 Electrons = 7
Protons = 8 Neutrons = 8 Electrons = 8

Slide 5
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
Slide 6
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

Organization of Life : Level 7 Lesson 1: Organization of
LifeMiKeKiM Educational Services: Biology7 The 7 th Level: The
Organism -All organ systems combine -All organ systems work
together
