Transcript Structure_and_Function_of_Cells

Flagella

STRUCTURE
– Whip-like extension
attached to the cell

FUNCTION
– Allows cell to move
Cilia

STRUCTURE
– Small and thin hair-like
structures surrounding
the cell

FUNCTION
– Helps the cell to move
Red Blood Cell

STRUCTURE
– Small, donut shaped
circles

FUNCTION
– Carries oxygen
throughout the body
Nerve Cell

STRUCTURE
– Cell body with a tail
and finger-like
extensions that branch
off from it

FUNCTION
– Carries messages
throughout the body
Voluntary Muscle Cell

STRUCTURE
– Long, ribbon-like
– Striped

Function
– Shorten and pull to
allow movement
The inside of the Cell

Organelle – the organs of a cell
Place a P next to the organelle that only
exists in a Plant Cell
 Place an B next to the organelle that is
found in a plant and animal cell

Nucleus (B)

STRUCTURE
– Large organelle
located in the center
of the cell

FUNCTION
– Controls the cell’s
activities, holds
genetic material (DNA)
Cell Membrane (B)

STRUCTURE
– Semi permeable,
flexible layer
surrounding the cell

FUNCTION
– Allows materials to
pass in and out of the
cell
Cytoplasm (B)

STRUCTURE
– Gel like substance
inside the cell

FUNCTION
– Holds organelles in
place.
Mitochondria (B)

STRUCTURE
– Bean like structure
with inner and outer
membrane

Mitochondria
FUNCTION
– Power house of the
cell – makes ATP from
sugar chemically.
Ribosomes (B)

STRUCTURE
– Dots found in the
cytoplasm and on the
Endoplasmic Reticulum

FUNCTION
– Makes proteins from
Amino Acids.
Vacuole (B)

– Bubbles of liquid found
in the cytoplasm.
– Large in plants
– Small in animals
Plant
Vacuole
Animal
Vacuole
STRUCTURE

FUNCTION
– Liquid storage with
some enzymes
Endoplasmic Reticulum (B)

STRUCTURE
– Network of tubules

FUNCTION
– Transports the
proteins made in the
ribosomes to where
they are needed
(packaged in the Golgi
apparatus)
Chloroplasts (P)

STRUCTURE
– Oval shaped organelle
containing chlorophyll

FUNCTION
– Makes food for the
plant cell through
photosynthesis by
capturing sunlight
Chlorplasts are the
green structures above
Cell Wall (P)

STRUCTURE
– Rigid layer of cellulose
outside cell membrane

FUNCTION
– Supports, protects and
shapes the plant cell.
Cell Wall
Recap

Eukaryotic – with a
nucleus

Prokaryotic –
without a nucleus
Chromosomes

Carries genetic
information in the
nucleus that gets
past on to the next
generation.
