Скачать или смотреть Life in Motion: Cytoplasmic Streaming

Despite being living things, plants don't seem like they do much. Beneath its static exterior, however, is a dynamical system where incredible biological processes are going on.

With a light microscope, we can see motion happening within certain plant cells. This video shows a timelapse of vesicles, which carry substances, being transported around a plant cell by an invisible highway known as the cytoskeleton. This intracellular (i.e. within the cell) transport process is known as cytoplasmic streaming.

Most of the clips were from an onion skin, from a run-of-the-mill onion you get from a grocery store. And yes, they are alive! One of the clips also shows cells from a plant i picked in a forest, which show the large chloroplasts also being pulled along the cytoskeleton.
