    The answer for this question is D. But surely photoautotrophs have chloroplasts? Can someone help? Thanks!

    I had that question in a mock recently, and I just ignored that part and focused on the fact it says Cyanobacteria and they are prokaryotes so don't have membrane bound organelles such as chloroplasts and mitochondria

    This is quite interesting as I would of thought they have chloroplasts, but after searching it up I saw that cyanobacteria does not have chloroplasts. And that's all you really need to know as it's a one mark question. Also it's helpful to know cyanobacteria are prokaryotic (as the other person mentioned). But I think cyanobacteria evolved to become chloroplasts as they basically are very similar to chloroplasts.
    Here is just what I was reading (you can go to the origin of chloroplasts bit)
    https://en.wikipedia.org/wiki/Evolut...f_chloroplasts
    What exam board are you on btw?
