Cytoplasmic streaming process
WebJul 7, 2024 · Cyclosis or cytoplasmic streaming is the vital process in plant cell. It is driven by organells-associated myosin motors moving along actin filament bundles. Streaming may play a significant role in promoting the exchange of molecules and proteins across organelle membranes. Why can’t you see the nucleus in an Elodea leaf?

WebJul 7, 2024 · Cytoplasmic streaming plays an important role in cell processes since it promotes solute exchange between the cytoplasm and organelles and enables lateral transport for extensive distances. Is cytoplasmic streaming active or passive? Cytoplasmic streaming is an active process because the motion of the organelles … WebAt this stage (called cytogenesis), the division of nuclei has been completed. The rest of the cells (cytoplasm and organelles) divide to form two new cells. Sexual reproduction (conjugation) Sexual reproduction of paramecia takes place under conditions of starvation. There are two mating types for paramecia, which are referred to as odd and even.
WebCytoplasmic streaming is characterized by the rapid movement of organelles and other cellular components throughout the cell. In plants, the process depends on actin filaments and myosin motor proteins and plays an important role in cell growth.
