The chloroplast is found only in plant cells. it is the organelle that conducts photosynthesis, but mitochondria are known as the PowerHouse of the cell, and store energy.
Okay, to start off, the basic difference between prokaryotic cells and eukaryotic cells is prokaryotic cells are cells without a nucleus, and eukaryotic cells are cells that contain a nucleus.
So based off that information alone, you can answer #1. Cell A does not have a nucleus (big circle shape), while Cell B does. Therefore, Cell A is the prokaryotic cell.
As for #2, prokaryotic cells and eukaryotic cells DO have similarities despite their differences. For instance, they both have some of the same organelles, like the plasma membrane, ribosomes, cytoplasm, and DNA.
Finally for #3, two differences are that #1, prokaryotic cells have nucleoids while eukaryotic cells have a nucleus, and #2, prokaryotes have circular DNA while eukaryotes have linear DNA.
Your best bet is finding a visual aid in a textbook or online to help you, so you can better identify organelles and eukaryotic/prokaryotic cells. Also, there are some cheesy videos out there on YouTube which I was forced to sit through in Bio class last year such as the Amoeba Sister's youtube channel which could help. Hope this helped!

A mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage. Regions of the genome (called genes) provide instructions for creation of protein molecules, which perform most of the important jobs in cells. Certain types of mutations are silent and have no effect, but others affect protein production in a variety of ways.
