Transcript Plant Cells vs. Animal Cells

Question of the Day?
• Why would plant and animal cells have
some similarities and some differences??
• Hmmm… Think about the differences in
each organisms way of life….
Here are some similarities….
now what are the differences??
THE PLANT CELL
1) Only Plants have a Large Central
Vacuole
• Storage tank for cell food (proteins,
carbohydrates, salt, water) or waste products
• filled with liquid
• FUNCTION: These plant-cell vacuoles provide
plants with structural support during rapid
growth.
• NOTE: Because animals need to move around and often have skeletal
systems they would not benefit by having the type of liquid vacuole
found in plant cells.  this would make cells quite rigid and less
flexible.
•
2) Plant cells have a Cell Wall.
• For example, plants have rigid cell body
walls, and animals do not.
• Why?? Because animals are mobile
creatures, these rigid walls would most
likely be maladaptive.
3)The Chloroplast
• are specialized to capture light energy for
conversion into energy-storing compounds.
• Contain green chlorophyll
• Animals don't use light energy to synthesize
sugars, obtaining them instead from the
other organisms they eat.
THE ANIMAL CELL
4) Only animal cells have centrioles!
Animal cells have centrioles to help with cell
division. Plant cells do not have them
• To look at division in plants and animal
cells…http://www.iknow.net/CDROMs/cell_cdrom/cellmovies.shtml

5 & 6) Flagella and Lysosomes are not usually found
in plant cells
