Philospohy & Plato help please!!!?

I am having such a hard time understanding philosophy so Im hoping I could get some help with a few questions What is Platos view of knowledge and what is the difference between knowing and true opinion? Considering Platos view of knowledge why does he think the body or senses can't provide knowledge? Why is the sensible world unable or inadequate for knowing? How does the doctrine of recollection fit within this picture? How does Plato make the connection between knowledge and death? Any help with these questions would be appreciated to help me better understand. Thank you!
