Cell Basics
•
•
•
•
•
All living things are made of cells
There are trillions of cells in your body
New cells are constantly replacing old cells
Cells contain parts called organelles
Plant and animal cells are different but we
are going to focus on the animal cell
The Building Blocks of Life
Cells are small units that hold all of the biological equipment
needed to keep an organism alive
• Organization
• Carry Out Different Functions
• Hold Hereditary Information
The Different Parts

There are so many parts, how can
we learn them all?
Compare the parts of a cell to
something easier to understand
and more memorable!!

REVIEW II
More cell parts to
remember!
Replace the function with the name:
Protects cell from
the outside
Combines small molecules to
form larger molecules
Controls the cell
Protein builders
Responsible for cell energy
Transports materials
Ribosomes
Endoplasmic Reticulum
Mitochondria
Golgi Complex
Cell Membrane
Nucleus
Mighty Mitochondria
• Multiple mitochondria in
each cell
• Takes nutrients and breaks
them down into energy
• Can grow, move and
combine with other
mitochondria
• Responsible for 90% of
energy needed by the body
Without Mitochondria
•
•
•
•
Cells would not have the energy to survive
Without cells, tissues die
Dead tissues result in organ failure
Without organs, our bodies would fail
Mitochondria
Cardiac muscle cell
Cardiac muscle tissue
Heart
Mitochondrial Diseases
Result from failures of the mitochondria
causing less energy to be generated
in the cell.
Symptoms
Mitochondria are very
important organelles!!
Mitochondria Quiz
The Parts Make the Whole
• All parts of the cell are important
• Cell could not survive without the system
• Just like the Cookie Factory
