Hi Shanna Norfolk pine do not take well to pruning. Once you cut the top off, the tree will either stop growing and die, grow from the side branches or send out another tip from a different growing point.At any rate, the tree will be misshapen and make an interesting experiment.i Shanna Norfolk pine do not take well to pruning.

Main Function of Microfilaments. Microfilaments or actin filaments are supposed to be the thinnest filaments present in the cytoskeleton in cytoplasm of eukaryotic cells.These are the linear polymer of actin filaments and mostly flexible, strong and resist buckling due to the multi-piconewton compressive forces.ain Function of Microfilaments.

They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis. Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of tracks for cell organelles and vesicles to move on.
