Transcript 2 Organelles Review Powerpoint

Bacteria Attacks!!
ORGANELLES
CILIA/FLAGELLA
CILIA AND FLAGELLA FUNCTION?


To move the cell around (flagella)
Or move things around the cell (cilia)
CELL WALL
CELL WALL FUNCTION?

To give the cell structure and to protect it
CELL MEMBRANE
FUNCTION?

To control what goes in and out of the cell
LYSOSOME
FUNCTION?

To digest things the cell doesn’t want/need



Old cell “parts” (organelles, etc)
Intruding bacteria/viruses
Lysosomes are cellular organelles that contain acid
hydrolase enzymes that break down waste materials
and cellular debris. They can be described as the
stomach of the cell. Lysosomes digest excess or wornout organelles, food particles, and engulfed viruses or
bacteria.
MITOCHONDRIA
FUNCTION?

To give the cell ENERGY!

Takes food and turns it into a useable form of energy
RIBOSOME
FUNCTION?

To make proteins…


NOT for ENERGY!!!
Proteins have functions in your body…you only use
proteins you EAT for energy…NOT ones your cells make
for you!
ENDOPLASMIC RETICULUM (ER)
FUNCTION?

To modify and package materials
NUCLEUS
FUNCTION?

Houses the DNA (protects it)
DNA
FUNCTION?

To tell the cell how to make proteins correctly
CHLOROPLAST
FUNCTION?

Performs photosynthesis to turn sunlight into
glucose

(The mitochondria then turns that glucose into ATP – an
energy source the cell can use)
VACUOLE
FUNCTION?

To store things

Water, wastes, foods
GOLGI BODY
FUNCTION?

To package things for export out of the cell

When a golgi vesicle is filled with digestive enzymes, it
can make a LYSOSOME! 
CYTOPLASM
FUNCTION?


The jelly-like material all the organelles reside
in…to give the cell support
Contains all the macromolecules the cell needs
