A - slnucue ( ithw leouuncls dsenii ) B - dioioachmtnr C - RER ( uoy can ees dahtteca isrsmboeo D) - ?? aym be oemssyslo E - elyggonc agneurls

weenathon  I don't think A is the nucleus, It seems more like a lysosome with digested material inside. If you watch the video below it shows the relative size of the nucleus to the mitochondria - a nucleus would be MUCH bigger than the mitochondria +5  
weenathon  https://www.ncbi.nlm.nih.gov/books/NBK26858/ There are very similar looking pictures in this article, it must be a peroxisome +3

thomasburton  Not sure looks like it might be free ribosomes or other such small cytosolic structure (I picked E too, thought B looked way too big!) +  
targetusmle  same here!! marked e thinking of it as a mitochondria +1  
msyrett  Glycogen Granules! They are not membrane bound and float freely in the cytoplasm. +4

bbr  It just further helps to tell us this is mitochondrial. I guess they are doing us a favor. +
