Photosynthesis in Prokaryotes, Protoctists and Plants only?

[waupor]

Is there any animals can produce organic food (such as glucose) by it self?
Can the animals produce some phtotsynthetic cells by genetic methods?

If it will, we can produce the food by ourselves without injection.
HA HA !! Dream will be true?

[thank.darwin]

Well first off prokaryotic cells are things like bacteria that don't have a nucleus and just have free floating DNA. They only have a cell membrane, cytoplasm, DNA, and ribosomes. So prokaryotic cells can't proform photosynthesis because they don't have chloroplasts! Another thing is that plant cells, not animal cells have chloroplasts (chloroplasts take in the suns solar energy and water and produce water and a carbohydrate). What do you mean - we can produce food with out injection?

-Please ask more questions if you want

I always had this dream where some scientist dude grafted cyanobacteria or something on the top of my head. That way I'd be eating whenever there's light and I'm not wearing a hat . But sorry all the food conglomerates would block this technology if it indeed existed.

[thank.darwin]

I have to say - that's one weird dream!
waupor- did you get what we said? If not, ask another question

[MrMistery]

I am sorry to dissapoint you thank.darwin but some prokaryotic cells ARE CAPABLE OF PHOTOSYNTHESIS. It is also true that they do not have any chloroplasts. So how do they do it? Well even if they do not have chloroplasts they do have assimilatory pigments. Bacteria stores these pigments in inclusions of the cellular membrane.
Some other organisms are also capable of photosynthesis even thought they do not have chloroplasts. At algee and Euglena virdis the pigments are located in organelles called chromatophores.
Now, about the question. There is no animal capable of photosynthesis because the animal cell does not have assimilatory pigments.
@mithrilhack
I hate to spoile your dream but you would still need to eat in order to get aminoacids, minerals&other stuff like that

I think I can transaminate my own aminos.

I think I can transaminate my own aminos.

All of them? how?

[mith]

well, plants can manufacture their own proteins by transaminating, if I had plant parts should I be able to do the same?

[Poison]

do u really have chloroplasts?

[MrMistery]

If someone had chloroplasts that means he was green. Everyone would run from him because they would think he is some kind of vampire or something...

Thank-you for clearing that up for me! My bio teacher didn't explain that there are prokaryotic cells that are capable of photosynthesis but now I know!

Glad to be of service thank.darwin
