What are plants and animals
made of?
• All living things are made of
cells.
• Cells are the building blocks of
all living things.
What are plants and animals
made of?
• There are two different kinds of
cells:
• Plant cells
• Animal cells
How Can Cells
Be Seen?
• Cells are very, very small.
• A microscope must be used to
look at cells.
Parts (Organelles) of an
Animal Cell
• Nucleus: controls what happens
in the cell
AKA: Control center
• Cytoplasm: gel-like material
that holds everything together
AKA: Packing material
Parts (Organelles) of an
Animal Cell
• vacuole: stores food, water, and
wastes
AKA: Storage bin
• mitochondrion: breaks down
food and turns it into energy
AKA: Power plant
Parts (Organelles) of an
Animal Cell
• cell membrane: thin layer
around the outside of the cell
AKA: The fence
Parts (Organelles) of a
Plant Cell
• Plant cells have the same parts
as animal cells plus two
additional parts.
• The vacuole in a plant cell has a
slightly different job.
Parts (Organelles) of a
Plant Cell
• vacuole: stores water and gives
shape to the cell
AKA: Shape keeper
• chloroplast: turns energy from
sunlight into food
AKA: Food factory
Parts (Organelles) of a
Plant Cell
• cell wall: hard outer layer that
protects the cell and provides
support
AKA: The wall
