Animal cells vs. Plant cells Interestingly
different, Surprisingly similar!

ANIMAL CELL
Centrioles
4
Centrioles

• Nonmembrane-bound organelles that occur in pairs
  just outside the nucleus of animal cells.
• Each centriole is composed of a cylinder or ring
  of 9 sets of microtubules.
• They organize cell division. Also give rise to
  cilia and flagella, structures that allow a cell
  to move and propel itself.
• Found only in animal cells.

Real Animal Cells
Human cheek cells
Cells from a frog

PLANT CELL
Cell wall
Chloroplast
Vacuole
7
Cell wall

• Cell walls lie outside the cell membrane
• They are porous and allow water, oxygen, and
  carbon dioxide to pass through easily
• The cell wall provides support and protection for
  the cell.
• Plant cell walls are made mainly of cellulose
  with fibers of protein to help strengthen the
  wall.

8
Chloroplast

• Organelles that capture energy from sunlight and
  convert it into chemical energy in a process
  called photosynthesis
• Plants cant move to get food to eat for energy,
  so they must get energy from the sun
• Inside the chloroplast are stacks of other
  membranes that contain the pigment chlorophyll (a
  green pigment, which is why most plants are green)

9
Vacuole

• A membrane-bound, fluid-filled sac that occupies
  much of the volume of a plant cell.
• The pressure of the central vacuole makes it
  possible for plants to support heavy structures
  like leaves and stems
• Also functions as a place to store water, since
  plants cant move to get water like animals can.

10
The Plastids

• Two Main Types of Plastids We Will Study
• Leucoplast Store Starch, typically found in
  root cells. Ex Potato
• Chromoplast Store Pigments which help, but
  cannot do photosynthesis on their own. Chromo
  Color (Red/Orange/Yellow)
• Ex Tomato Skin Cells

11
Walls and Membranes

• Important to note
• Plant cells have a cell wall and a cell membrane
  both
• Animal cells only have a cell membrane, but no
  walls.

So which structures are found in both animal and
plant cells? Which are found only in plant
cells? Which are found only in animal cells?
Lets use a Venn Diagram to compare the two
types of cells.
