Document Summary
Movememtn can be created and produced in ways we may not necesasrily think about. Not always made from mysoin / mucsle cells. All multicellular organisms can move, but animals are the only one who can move from place to palce based on the myosins they are unique because of the organization of the moelcules and use the muscle cells. These components the actina dn motor proeins can be ofound within the simple fungus as well. What really matters is the structural organization the isoforms of the ones in the fungus , which have evoled allowing the production of the superstructure , sarcoemre. The 3d super structure allows us to really move to place to place. Which allows us to eb envous of sme animals like the cheetah. etc. As animals grew larger the surface area to volume ratio is reduced. Diffusion is no longer able to provide materials.
