Jupiter and Venus are much more plausible than the sun. There are just simply no available building blocks in the sun. The sun's gravity is so strong that it sorts out it's elements by atomic weight almost perfectly. Hydrogen, Helium, and then some heavier ones. At that point... we're just out of building blocks. What would we build the life with? Swirls of Hydrogen? Hydrogen can only bind to itself, one at a time. There's no way to make any structures. As someone with a biochem degree (which is admittedly biased towards earthling life): my understanding of life is that it's fundamentally about selectively letting certains molecules in to create energy and chemical gradients. It's about separating one's inside from the surrounding, so the inside can be manipulated. The insides of cells are a very different solution than outside--- and along similar lines of homeostatis, the blood of dolphins is very different from sea water. I just have a ton of difficulty seeing how a uniform pool of plasma could hold life.
