Plant Cell Motility and Laser Microsurgery of Cytoplasmic Strands
Plant cells are shaped by rigid cell walls. Osmotic forces press the plasma membrane tightly against these walls. The walls can be removed with enzymes. The remaining structures, the protoplasts, are now bordered by the plasma membrane. Since the shaping force of the wall is missing, isolated plant protoplasts are usually perfectly spherical in shape as a result of non-directional osmotic forces. Run time 04:19
