More Cell Videos

This video was produced by a 13 year old using a microscope.  It clearly shows the nucleus, cytoplasm, and cell membrane of a red blood cell.  How come you can't see the mitochondria (the machine/power station of the cell), the vacuole (the vehicle that brings things in and out of the cell), cell wall or chloroplast?

The video shows the structure of a plant cell, as well as the movement of chloroplasts (the part of plant cells responsible for photosynthesis).

When cells divide to produce more cells, first the nucleus divides, then the cytoplasm.

How a virus spreads using a cell

Don't forget to notice the cell membrane (outside of the cell) , the vacuole (the transport thing) and the nucleus (the command center that says "make more of this!")
