Animal and Plant Cells
Write down at least three things you see that are the same.
Then write down at least three things you see that are different.
Today’s Lesson
• Students will differentiate
between structure and function
in plant and animal cell
organelles, including
cell membrane, cell wall, nucleus,
cytoplasm, mitochondrion,
chloroplast, and vacuole.

What is Structure?
• Structure is what an object looks like or how
it is made.
• Can you describe the structure of the object
below?
What is function?
• Function is what something does, or its JOB.
• What is the function of the objects below?
What if it’s structure was different?
How would that affect it’s function?
Or
Main Point
• An object’s
structure
determines its’
function. How it’s
made determines
what it does.
*Cell Membrane
• Cell Membrane-Controls what goes in and
out of the cell
• How does the cell membrane’s structure
determine it’s function?
*Cell Wall
• Cell Wall-A cell wall gives a plant cell
structure and support.
• How does a cell wall’s structure determine it’s
function?
*Nucleus
• Nucleus-the brain of the cell. Controls all the
cell activities and holds the DNA.
• How does a nucleus’ structure determine it’s
function?
*Cytoplasm
• Cytoplasm- The jelly-like liquid in a cell that
holds all the cell parts(organelles) and helps
organelles move.
*Mitochondria
•Mitochondria-Releases
energy for the cell to
use.
*Chloroplast
• Chloroplast-contains chlorophyll, traps
energy from the sun, performs
photosynthesis and gives energy in the form
of glucose(plant sugar)to the plant cell.
*Vacuole
• Vacuole-stores water
and waste in both
plant and animal
cells
• How does a vacuole’s
structure determine
it’s function?
