Ribbon of Life Order(simplest to most complex)

• Atoms
• Molecules
• Organelles
• Cells
• Tissues
• Organs
• Systems
• Complex Multicellular Organism

3
Atoms

• Atoms
• Definition- the smallest units of an element
• Extra Information- They are the fundamental
  material things are made of They have protons,
  neutrons, and electrons.

4
Molecules

• Molecules
• Definition- combinations of atoms bonded together
• Extra Information- Atoms bond, or stick together,
  to make molecules.
• Example two hydrogen atoms bond with an oxygen
  atom and form a molecule of water (H2O)

5
Organelles

• Organelles
• Definition- the complex structures inside cells
• Extra Information- Thousands of atoms bond to
  form complex molecules, these are organized into
  special structures called organelles.
• Different organelles perform different jobs.

6
Cells

• Cells-
• Definition- the fundamental units of life
• Extra Information- Two kinds of cells
  Prokaryotic-bacteria and Eukaryotic- animal,
  plant, protist, fungus
• Eukaryotic cells have a nucleus, prokaryotic
  dont.

7
Tissues

• Tissues
• Definition- lots of cells of the same kind
  working together
• Extra Information- Only in multicellular
  organisms (plant and animal). Not in bacteria,
  protists, or single-celled fungi.

8
Organs

• Organs
• Definition- two or more tissues working together
• Extra Information- Animals have many organs.
  Examples in humans- lungs, liver, kidney, heart.
• Plants have 3 organs- roots, stems, and leaves

9
Systems

• Systems-
• Definition- organs and tissues working together
• Extra Information-
• Examples in humans- circulatory, respiratory,
  nervous, and digestive systems
• Example in plants- vascular system

10
All this makes

• Complex Multicellular Organism-
• Definition- plants and animals
• Extra Information- Plants and animals are highly
  organized, complex, free living life forms. They
  are organisms made of up to millions of cells
  organized into many kinds of tissues, organs, and
  systems.
