4. Finding the size of a sea urchin embryo Observe the image of the sea urchin embryo. 50um Photo credit. Notice that the size of the scale bar is 50 um. Keeping this image available, watch the se urchin embryo cell division movie. Calculate the diameter of a sea urchin embryo at the one-, two-, and four-cell stages. Show your calculations below. If that video doesn't play (it unfortunately requires Flash), you can try this similar but longer one that involves a longer story of sea urchin romance preceding fertilization and zygote divisions! It lacks a scale bar, but you can use the scale bar from the image above. https://www.youtube.com/watch?v=4445zftLCDQ a. One cell-your calculations: b. Two cells-your calculations: c.
