A Dissecting microscope has no stage (the bit you put the sample
on) as such, having just a flat surface, giving you plenty of room to
manipulate the sample. Illumination comes from the sides. This would be
the most appropriate for finding eggs in peat, in a petri dish. 10x is
ample magnification. The student microscope, having a stage, would
require illumination from below, and hence the sample would have to be
mounted on a slide. The objectives supplied (100x, 400x) would be more
suitable for examining cells or maybe checking out individual infusoria
(always good for a laugh) If you want to find eggs, or see whether
they're developped, get the dissecting microscope.
hope this helps
