~ A mole is a unit of 6*10^23.
~One mole of carbon atoms has a mass of exactly 12 g.
~ Because magnesium atoms each have twice the mass of carbon atoms ( 24Mg compared with 12C), one mole of magnesium has a mass of 24 g.
~ Rather, one mole of any element has a mass in grams that is equal to its relative atomic mass.

Here are my quick example slides:
1st Picture:
just a title page
2nd Picture:
I just gave the definition of an organelle you could go more in-depth. The picture doesn't have to be there, of course.
3rd Picture:
Examples of organelles in plant and animal cells, these are just examples of how I would do one.
This was just to show how you could do it because it would be kind of hard for me to explain just in words.
Hope I could help! c:
