Organelles & Levels of Organization
Use these slides to study for your test on Thursday!

Organelles
3
*Parts of a cell
Mitochondria
Function: ● Breaks down sugar (glucose)
to release energy
● “POWER HOUSE”
In BOTH animal and plant cells.
VacuoleFunction: ● Stores food, water, and
waste
● It is much LARGER in PLANT cells
In BOTH animal and plant cells.
Nucleus
Function: ● Controls all cell activities.
● The BRAIN of the cell
● Contains hereditary/genetic information
In BOTH animal and plant cells.
ChloroplastFunction: ● Uses energy from the sun
in a process called photosynthesis to make sugar (glucose) and oxygen.
● ONLY IN PLANT CELLS
Cell Wall
Function:
● Supports and protects
● ONLY IN PLANT CELL
Cell Membrane
Function:● Controls movement of
material in/out of the cell
In BOTH animal and plant cells.
CytoplasmFunction:● jelly-like substance that
supports and protects organelles
In BOTH animal and plant cells.
RibosomeFunction:● Synthesizes (creates)
proteins
In BOTH animal and plant cells.
Golgi BodyFunction:● Helps make and package
material to be transported out of cell
In BOTH animal and plant cells.
Levels of Organization
13
*Order of living things
CELL● ALL living things are made
of cells.
● The smallest unit of a living thing
TISSUE
A group of CELLS working together to perform a specific function (job).
ORGAN
A group of TISSUES working together to perform a specific function (job).
ORGAN SYSTEM
A group of ORGANS working together to perform a specific function(job).
ORGANISMLiving thing that can perform all processes necessary for life.
Levels of Organization● What order did you put them in?
● SMALLEST:
● 1.
● 2.
● 3.
● 4.
● 5.
● 6.
● LARGEST ^^
