“Cell Structure”

CHLOROPLASTS Green organelles that
make food found only in plant
cells

CHLOROPHYLL A green pigment that
gives leaves & stems their color
Captures sunlight energy that is used to produce food called glucose
Glucose is a type of sugar

MITOCHONDRIA Organelles that release
energy from food This energy is released
by breaking down food into carbon dioxide
AKA the powerhouse b/c they release energy from food
Some muscle cells have 20,000 mitochondria

RIBOSOMES
Make proteins Float freely or attached
to the endoplasmic reticulum (ER)
Ribosomes are made in the nucleolus

ENDOPLASMIC RETICULUM
A series of folded membranes that move materials (proteins) around in a cell
like a conveyor belt Smooth ER – ribosomes
not attached to ER Rough ER – ribosomes
attached to ER

GOLGI BODIES (GAWL jee) Stacked flattened
membranes Sort and package
proteins

VACUOLES Temporary storage
spaces Store food, water,
waste

LYSOSOMES (LI suh sohmz)
The word "lysosome" is Latin for "kill body."
The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies.
Break down food molecules, cell wastes & worn out cell parts
