what is the shape of an elodea cell? where is the nucleus in it? explain about the moving chloroplasts in it?

Question

how do the chloroplasts move, describe if they move at same speed, in same direction.

Answer 1

The shape of the typical Elodea cell is rectangular or boxlike
(http://biology.arizona.edu/sciconn/lessons2/McCandless/teach_sec.htm )
On this site you find a photo of Elodea cells (http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/Bio%20101/Bio%20101%20Lectures/Cells/cells.htm)
Here an enlargement (http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/Bio%20101/Bio%20101%20Lectures/Cells/elodea__X_400.jpg)
The green structures are the chloroplasts and the clear ones with gray border near the cell walls are the nuclei.
The chloroplasts will show an obvious flowing movement around the periphery of the cell. This movement is called cyclosis or cytoplasmic streaming. (http://botit.botany.wisc.edu/courses/botany_130/Lab_topics/afPlantCell.pdf).

Answer 2

I don't remember where the nuclei are in elodea cells, but the chloroplasts don't move in the same direction or at the same speed. I don't understand the question about movement of structures, but I assume you could, considering that everything in a cell would probably have some kind of movement. In onion cells, I remember the skin cells' cytoplasm was clear. The nuclei are in the center (I'm pretty sure), and if you add iodine, the nuclei turn orange/red. I don't understand your question about depth. I hope that helped a little. I only know the stuff that we covered in biology labs, so I don't know the answers to some of the questions.
