HAPPY THURSDAY
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 and
are found in both plant and animal cells
Ribosomes: Are NOT membrane bound and are
in prokaryotic and eukaryotic cells

CUPS
Standard
B.10C – Analyze the levels of organization
in biological systems and relate the levels

increase in complexity?

Levels of Organization
Atom – the smallest component of an element
EVERYTHING is made up of atoms
Levels of Organization
Molecule
consisting of one or more like
atoms
OR
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),
