Compare photoransistor with photodiode?

I guess for the three areas, the simple options are really just "Higher", "Lower", "Same", or "Does not apply".

I'll give you the hint that the last one ("Does not apply") does not apply

It may also be worth you defining what you will understand as the meaning of "sensitivity". Does it mean:

a) The lowest light level detectable
or
b) The highest current at a given light level.
or
c) range of wavelengths detectable

It could also (if you're going for a really good answer) discuss the saturation characteristics.

You might also consider if there is more than one mode of operation for these devices and whether that affects the properties in question.

I guess only you know what is appropriate, but the answer to this question might be between three words and your very own publication

 

The post above is a perfect example of something you should ignore.

It contains negative information (you'll know less after reading it than you did before)
