You can say that but chloroplasts do not have uniform morphology across different species. Moreover some organisms such as red algae have chloroplasts of different origin. Real indicator would be lets say number of chloroplast ATP synthases and/or light harvesting photosystems; these can be perhaps indirectly approximated by the total surface area of the ...

As @wysiwig already pointed out the different morphology of chloroplasts is something that is hard to come by. This influences the amount of chlorophyll in these organelles which is the key for photosynthesis. So it is very difficult (to impossible) to compare chloroplasts of different plants as they differ pretty much. There is one paper from 1929 which ...

I had to re-read your last sentence a few times to make sure I understood it correctly, but I think that now I do, and I can answer your question. What you're talking about are thermophiles. They're small organisms that love hot conditions - up to nearly 250 degrees Fahrenheit. They can be found places with a lot of hot water, such as hot springs - and, ...

The light dependent reactions involve an electron transport chain with enzymes embedded in the thylakoid membrane. NADPH and ATP are generated in the stroma and water is oxidized in the thylakoid lumen. I'm not sure if it's correct to say that the light independent reactions occur "at the thylakoid" since, in plants, they could really occur anywhere in the ...

Energy from an electron transport chain is used to actively transport protons from the stroma to the thylakoid lumen. Thus the lumen has a relatively higher proton concentration and therefore a lower pH than the stroma. Higher $[H^+]$ means lower pH. Lower $[H^+]$ means higher pH. Keep in mind that the flow of actively transported protons from the stroma ...
