Mechanism Myosin protein surrounding chloroplasts Actin protein filaments attached to the plasma membrane of cells. Myosin on the chloroplasts binds to actin filaments in the plasma membrane. Myosin slides along the actin filaments by contracting and releasing, using ATP as an energy source. THE FORCE OF THE ORGANELLE MOVEMENT PULLS THE organelles) The mechanism of movement of organelles in the plant cell cytoplasm is called What is the purpose of this phenomenon? hy is this necessary in plants but NOT animals? Is the cytoplasm pulling the organelles with it or is the reverse true? Explain Plants have Golgi and Mitochondria just like animals do The function and location of these organelles is the same in plant and in animal cells. Answer the next three questions using your Major Biology knowledge. Where are the Golgi and Mitochondria found in plant cells? What is the function of Mitochondria in plants the Golgi? Do the Mitochondria an lgi move with cytoplasmic Streaming or are they stationary in the cell? Does the Nucleus move?

Solution

It is necessary on plants as plant cells contain organelle called chloroplasts. Cytoplasmic streaming moves these organelles towards the regions in the cell where they can utilise maximum amount of energy.

Cytoplasmic organelles pulls the cytoplasm with it. Cytoplasm is filled with organelles powered with actin and myosin protiens. Cytoplasmic streaming occurs as myosin-coated organelles move along actin filaments in the cytoskeleton of the cell, causing the cytosol to move as well.
