Organelles suspended in gel-like goo… empty space within the cell
NUCLEUS• The control center of the cell • Largest organelle in animal cells• Contains genetic material DNA
DNA
Nucleolus
Nuclear envelope
Nuclear pores

• The nucleolus is where the assembly of ribosomes begins.

NUCLEOLUS
CYTOSKELETON
• Helps the cell maintain shapeMicrotubules & Microfilaments

Mitochondria
• Singular: Mitochonrion Plural: Mitochondria• The “Powerplant” of the cell
– Stores energy in the form of ATP
MITOCHONDRIA
RIBOSOMES• Can be attached to Rough ER OR free in
cytoplasm.• This is where proteins are made!

Ribosomes
Endoplasmic Reticulum
•Two types•Rough ER •Has ribosomes•protein making
•Smooth ER•No ribosomes attached•Makes lipids
GOLGI APPARATUS• Modify, sort, & package molecules from ER
for storage or transport out of cell- like the post office
• Ships proteins to their final destination.

LYSOSOMES
•Digest food, unwanted molecules, old organelles, cells, bacteria, etc.
•Like trash men: they take out the garbage!
•Also known as suicide sacs
• Plant cells: large• Animal cells: small• Storage space
Vacuole
VACUOLES
Chloroplast
• In plant cells• Use energy from the sun
to make food
CHLOROPLAST
