Effect of Temperature on Cytoplasmic Streaming on Permeabilized Nitella Cell

Cells have evolved various ways of movement of materials and Structures within the cell and the common example of this is the rapid Cytoplasmic Streaming seen predominantly in some Algal Cells and other higher plant cells and also in many protozoans in which it is called as Cyclosis. Changesin the rate of Cytoplasmic Streaming of PermeabilizedNitella cell at different temperature was investigated by motion of small organenelles or vesicles passing from one arbitrary point to another. The time taken to pass the particular distance between the above two points was recorded through the stop watch. Theorganenelles selected were usually of diameter within 2 to 3 um which are dispersed in the endoplasm and considered to reflect bulk flow due to Cytoplasmic Streaming.
