What's the immediate source of energy for chloroplasts to move around the perimeter of cells for elodea cells

Question

This is the last question that I need help for the experiment involving Elodea cells. Please help me out with this last question. Thank you.

Answer 1

My teacher told me that it was the motor protiens moving along the cytoskeleton of the elodea cell. Ofcourse the motor protiens themselves are powered by ATP.

Answer 2

In some plant cells ( such as elodea)there is a rapid rotatory cytoplasmic movement, limited to the peripheral parts of the cell next to the cell wall, which carries chloroplasts and granules along. This movement may be increased by light, and is dependent on temperature and pH. http://www.daviddarling.info/encyclopedi...

Energy comes from ATP.
