Detailed explanation-1: -Cytoplasmic streaming in plant cells is best observed under electron microscope.
Detailed explanation-2: -What is clearly visible in plants cells which exhibit cytoplasmic streaming is the motion of the chloroplasts moving with the cytoplasmic flow. This motion results from fluid being entrained by moving motor molecules of the plant cell. Myosin filaments connect cell organelles to actin filaments.
Detailed explanation-3: -Cytoplasmic streaming assists in the delivery of nutrients, metabolites, organelles, and other materials to all parts of the cell (Chebli et al., 2013; Van de Meent et al., 2008; Verchot-Lubicz and Goldstein, 2010).
Detailed explanation-4: -cytoplasmic streaming, also called protoplasmic streaming, the movement of the fluid substance (cytoplasm) within a plant or animal cell. The motion transports nutrients, proteins, and organelles within cells.
