Looking Inside Cells

Create a chart with four columns:

Name Description
Function
Drawing
Cell Wall
Description: Rigid, nonliving, made of
cellulose, surrounds
plant cells.
Function: Protects and
supports the cell.
Cell Membrane
Description: Thin,
flexible, has pores.
Function: Semipermeable, controls
what substances
enter and leave the
cell. “Gate-keeper.”
Cytoplasm
Description: Clear,
thick, gel-like fluid.
Function: Supports all
the organelles (tiny
cell structures.)
Nucleus
Description: Large,
oval, surrounded by a
nuclear membrane
with pores.
Function: Directs all cell
activities. “Brain.”
Chromatin/Chromosomes
Description: Strands of
DNA inside the
nucleus
Function: Is the genetic
material that are the
instructions to direct
the cell.
Nucleolus
Description: Round
object inside the
nucleus.
Function: Makes
ribosomes.
Mitochondria
Description: Rodshaped, has a double
membrane.
Function: Produce
energy.
“Powerhouse.”
Endoplasmic Reticulum
Description: Maze of
passageways. Some
have ribosomes stuck
on the outside, some
do not.
Function: Carry
proteins and other
materials to different
parts of the cell.
“Hallways.”
Ribosomes
Description: Small,
round, grain-like. Can
be found in cytoplasm
or attached to the ER.
Function: Produce
proteins.
Golgi Bodies
Description: Flattened
stack of sacs.
Function: Receive,
package, and
distribute proteins.
“Mail room.”
Chloroplasts
Description: Rodshaped, green.
Function: Produce
sugar for plants.
“Cafeteria.”
Vacuoles
Description: Water-filled sacs.
Function: Store water, food, wastes.
Lysosomes
Description: Small,
round, contain
digestive chemicals.
Function: Break down
large food particles
into small ones,
digest old cell parts.
“Clean-up crew.”
