Two features that Eukaryotic cells have and prokaryotic cells lack:
1) Nucleus
2) Nuclear bound organelles like chloroplasts, Mitochondria, Golgi appratus etc
Hope this helps!
<span>The question makes it seem that you looked through both types of microscopes at specific samples? As for how they would differ, a light microscope's level of magnification is limited by the physical characteristics of light and therefore can only see objects as small as organelles inside of a cell. A scanning electron microscope, however, does not use light, it uses a beam of electrons to visualize the sample. Electrons are much smaller than the light beam and are able to image much smaller objects, such as molecules and atoms.</span>
Producers are green plants or photosynthetic organisms that are the basis for the other living parts of any ecosystem. Producers need to have access to light to produce food. Few producers will be found deep below a lakes surface simply because the deeper you travel under water the less light penetrates those deeper layers.
