Answer 1

I thought c at first, but now I am thinking about it when it said bacteria.

Answer 2

in photosynthesis carbon-dioxide is used. So it is dfntly not the correct answer !

Answer 3

I know it wasn't that one.

Answer 4

No it's okay...photosynthesis performed by bacteria like cyanobacteria is similar to that of plants.

Answer 5

And glucose is what is made to be used for energy, so that couldn't be it either.

Answer 6

correct !

Answer 12

Though the question is poorly worded !
There are some bacteria which perform non-oxygenic photosynthesis.

Answer 13

Yeah, my school has a lot of that.

Answer 14

Just for ur knowledge there are some bacteria collectively called as sulfur bacteria performs non-oxygenic photosynthesis and do not use water as a substrate and thus do not produce oxygen.

Answer 15

But still seeing ur options, oxygen is the only possible answer !

Answer 16

Thanks, I was needing to know about that for some further assignments. :)
