Bellwork:List the four cell structures that are
in both the Prokaryotic and Eukaryotic Cells
Then….Glue the Pro vs Eu Y chart on page 8
(regular style)
Add these to your organelle notes for clarification
Mitochondria: Have their own DNA and RNA andare found in both plant and animal cells
Ribosomes: Are NOT membrane bound and are in prokaryotic and eukaryotic cells

StandardB.10C – Analyze the levels of organization in biological systems and relate the levels
to each other and to the whole system
Essential Question How do the levels of organization show an
increase in complexity?
The Study of Life
I. Introduction to Biology
Bios = "life"Biology
Logos = "study of"
Levels of Biological Organization
1. atoms2. molecules3. organelles4. cells5. tissues6. organs7. organ systems8. organism
Levels of Organization
Atom – the smallest component of an elementEVERYTHING is made up of atoms
Levels of Organization
Molecule consisting of one or more like
atomsOR
two or more different atoms in a compound
Levels of Organization
• Organelle – *tiny organs*a specialized part of a cell having some specific function; a cell organ.
Levels of Biological Organization
• Organism – a living thing made up of one or more cells.
• Unicellular – an organism composed of one cell, can carry on all the activities necessary for life
• Multicellular – An organism composed of many cells, different cells carry out different jobs (division of labor),
