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

Elodea Cytoplasmic Streaming
About 10-15 minutes after preparing a wet mount of an elodea leaf, evaporation of some of the water makes it possible to see chloroplasts in motion inside of the cytoplasm. "Cytoplasmic streaming" is defined as the movement of the fluid substance (cytoplasm) within a plant or animal cell. This is the mechanism for the transport of nutrients. Run time 02:31.

mosses and liverworts
Non-vascular plants have no true roots, leaves, stems, or flowers. They also have no internal circulatory system for bringing water to the various parts of their bodies.  Therefore, non-vascular plants are typically found in very wet places. This video gives a brief overview of two non-vascular plants, mosses and liverworts. Run time 0:50.

3D Animation of a Heart Attack
This 3d medical animation illustrates the story of a heart attack from a blocked coronary artery due to th inflammation of blood vessels. Beginning with damage to the endothelial arterial wall, the animation shows how a white blood cell entering the wall of the artery changes into a macrophage, grabbing and digesting cholesterol. As the cell does its job, it transforms into a foam cell, which, unfortunately, becomes part of the plaque within the blood vessel wall. Ultimately, over a period of

Paper Towel Plants with Curious George
This video from Curious George shows students helping bean seeds sprout (germinate) outside of soil by meeting their essential needs for moisture, temperature, air, and light. The children place the beans and a wet paper towel inside a zippered plastic bag and leave them undisturbed in a warm, well-lighted place. After two weeks, the students return and observe that the beans have sprouted and, like apple seeds, will one day grow to be fully developed plants. Run time 01:26.
