Comparing Organelles to Body
Systems
Cell Wall
• A stiff wall surrounding the cell membrane of
a plant cell needed for protection
• Responsible for the shape/support of the cell
Body System?
Skeletal
Protects organs
and gives
organism its
shape/support
Cell Membrane
• A protective barrier between the cytoplasm and outside
of the cell
• Controls what enters and leaves the cell
Body Systems?
Integumentary
System (Skin)
Protects against
invaders and also
controls what enters
and leaves an
organism’s system.
Cytoplasm
• Gel-like fluid in which organelles are supported
• Transports materials within the cell
Body Systems?
Circulatory
transports materials
around the body
Nucleus
• The control center of the cell and directs
all cell activities
Body Systems?
Brain and
Central
Nervous
System
Controls most
body functions
Mitochondria
• Mitochondria breaks down nutrients to release
energy using oxygen (cellular respiration)
Body Systems?
Digestive
Breaks down food
into molecules used
by an organism for
energy release
