Nucleus

• Functions

– Controls the activities of

the cell

– Contains the DNA of the

cell

• Mayor

Nucleus

Nuclear Membrane

• Function

– Encloses the nucleus

– Controls the movement

of substances in and out

of the nucleus

• Mayor’s security guard

Nuclear membrane

Endoplasmic Reticulum

• Function

– Transport Materials

Around Cell

• Factory

Mitochondria

Cytoplasm

• Jelly-like fluid that fills

the space within the cell

• Controls the movement

of molecules within the

cell

• Traffic lights

Cytoplasm

Lysosomes

• Function
