The cytoskeleton acts as a "track" on which cells can move organelles, chromosomes and other things.
Epithelial cells cover the surface of the intestine.
No-one really knows the exact mechanism for 'heliotropism' -or sun tracking.It appears that an external factor ( the sun) is triggering a not -yet understood factor within the plant.It is still being researched. Heliotropism is the term used to describe the tracking of the sun by the flower buds of sunflowers. Other plants also have flowers and/or leaves that track the sun. First, let's discuss how the plants are able to track the sun. There is a collection of specialized cells at the base of the flower bud or leaf called a pulvinus that carry the "motor" cells that enable the plant leaf or flower to track the sun. These cells enlarge or shrink according the turgor pressure from the water inside them. In response to blue wavelength light, potassium ion concentration increases in the "motor" cells on the shadow side of the pulvinus. With the increase of potassium ions the osmotic potential in the cells becomes more negative and the cells absorb more water and elongate, turning the face of the flower to the sun.
Normally we would say that nutrients are carried in the blood, but you are correct, it is the plasma portion of the blood that carries nutrients, as compared to the red blood cells which carry oxygen.

The cells that lines the GI Track into the bloodstream
A normal track is about 800 meters, to find a quarter of a track simply divide by 4. 800 divided by 4 is 200. A quarter of a track is 200 meters. Hope I helped!
Well if its your typical 400m track, then 4 times.

how long is the track? at mine it is 4 times.
