In this biology lesson from Mahalo.com, adjunct professor Mary Poffenroth discusses the differences between animal and plant cells. Poffenroth focuses mainly on the aspects of plant cells that are not present in animal cells such as rigid cell walls, chloroplasts, and vacuoles. For more biology tutorials, visit the Mahalo.com YouTube channel.

All cells perform a few basic functions
including the production of proteins, energy refinement and
reproduction.
http://www.youtube.com/watch?v=9exRxOozxtI Eukaryotic cells contain a membrane-bound nucleus
that houses the cell's DNA and they all contain membrane-bound
organelles such as mitochondria.http://www.youtube.com/watch?v=9exRxOozxtI  However, amongst eukaryotic
organisms, plant cells and animal cells have many significant
differences.

One of the major differences between
plant and animal cells is that animal cells are heterotrophic, which
means they must gather energy from their environment.  Meanwhile,
plant cells are autotrophic, which means they can create their own
food.
http://www.youtube.com/watch?v=9exRxOozxtI  Plant cells can create their own food because they are
photosynthetic, they convert light energy into chemical energy using chloroplasts, an organelle that only plants have.http://biology.clc.uc.edu/courses/bio104/photosyn.htm 

Plant Cells
---------------------------------------------------------------------

Plant cells produce their own food through photosynthesis.http://www.youtube.com/watch?v=9exRxOozxtI  Photosynthesis
is the conversion of light energy into chemical energy, and the
organelles that allow plants to accomplish this feat are called
chloroplasts.http://biology.clc.uc.edu/courses/bio104/photosyn.htm  Plants also have rigid cell walls made of cellulose
which support the structure of the organism as well as water
regulation.http://micro.magnet.fsu.edu/cells/plantcell.html  Plant cells have a central vacuole which can be
responsible for water regulation, storing nutrients, or even storing
poisons, depending on the species of plant.http://www.youtube.com/watch?v=9exRxOozxtI 

Animal Cells
---------------------------------------------------------------------

Unlike plant cells, animal cells are
heterotrophic, they must gather energy from their environment. Animal
cells do not have rigid cell walls like plants, only a plasma
membrane. The lack of rigid cell walls allows animals to develop
greater diversity of cell types, tissues, and organs. Animal cells
have two things that plant cells do not, centrioles and intermediate
filaments.http://www.youtube.com/watch?v=9exRxOozxtI Centrioles are paired organelles which serve as an
organizing center for microtubules.http://micro.magnet.fsu.edu/cells/centrioles/centrioles.html  Intermediate filaments are
elongated structures within the cytoplasm which provide the cell with
tensile strength.http://ghr.nlm.nih.gov/glossary=intermediatefilaments

thankx 4 video it helpl!!!

[MrMcfrogz]

@The1updudes same here bro

[The1updudes]

i got to do this for school T_T HI other classmates :P

[SkittlesLover54]

It helped me very much you should make another video about decimals, I bet you would be good at it. Thank You.

[SkittlesLover54]

cool



[Abercrombie10112]

Omg mahalo ? Is a guitarist o.O? I'm confused

[Vadski1988]

Thanks alot! This helpped me out alot studying for my test.

[supergrocerybag]

its was ok but whole cell (animal vs plant) comparison diagrams would have made this perfect.
