SALE TODAY: Learn Piano on iOS http://bit.ly/PianoAppSale 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=9exRxO... 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=9exRxO..., 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=9exRxO... 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/bio...
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=9exRxO... are paired organelles which serve as an organizing center for microtubules.http://micro.magnet.fsu.edu/cells/cen... filaments are elongated structures within the cytoplasm which provide the cell with tensile strength.http://ghr.nlm.nih.gov/glossary=inter...
