Photosynthesis

[LightBearer]

Photosythasis is a very complex process involving some 70 chemical reactions.  It produces oxygen on land and in the oceans and is essential for life on this planet.  Life could not come about without it.

For Photosynthasis to work all 70 complex chemical reactions are needed, not 58 or 69 but all 70 must work together simultaneously at one time or no Photosynthasis takes place, therefore no life.

Therefore Photosynthasis can only be a creation and not a gradual evolution.  All living things need to take in oxygen including plants, so Photosynthasis had to happen suddenly at at once for it to work at all.  So there could be no primitive plants around with some of the reactions needed because without all 70 complex chemical reactions fully working ie, Photosynthasis,  these or any life couldn't exist.

Let the evolutionist Barney-land speculation begin.

Actually, some plant types, like algae, fungus, and mushrooms do not require photosynthesis to live. Today's plants could have evolved from such plants.

2000 years ago:
Gosh, I can't figure out what lightning is. Must be the gods.

Today:
Gosh, I can't figure out how photosynthesis could happen on its own. Must be the gods.

Give us a break already.

Photosynthesis only works in leaved plants, not in all types of plants.

Interesting, LightBearer.

Where did you get this info? Is this scientifically correct? What is your source?

Other plants could not evolve from Mushrooms or anything else without Photosythasis it needs all 70 chemical reactions to work immediatly for these so-called evolved plants to survive and live. Mushrooms eat broken down and dead plants, where did these plants come from without Photosynthasis.

Well, Photosynthesis actually PRODUCES Oxygen, it doesn´t need it. Actually Oxygen is bad for photosynthesis plants, Carbon Dioxide is good.
Photsynthesis is a process involving certain wavelength of visible light, Carbon Dioxide and water to produce a certain sugar.
Without photosynthesis, there would be no life as we know. I used to learn the gist of photsynthesis, which cycle working how.. Knowing the chemical mechanisms behind it, it isn´t as wonderful as it seems. PLease note, that those chemical compounds obey all the laws of chemsitry and physics. That severely limits the chances on how the chemicals can react with each other.

To add, photosynthesis doesn´t oxygen in the complete oceans, because the light from the sun penetratse only so far into the oceans. Additionally, the water doesn´t get mixed up so much, when you go deeper.

The evolution of plants remains a mystery.


Why can't I see the usernames? It just appears as basic black type! Is it this site or my computer?

Ah, the old irreducible complexity argument again. Maybe a little reworking of your original post will help illustrate the fallacy of this argument.

"The human body is a very complex machine involving some 70 organ systems. It sustains and nourishes the most powerful brain in the animal kingdom. Civilization would not be possible without it.

For the human body to work all 70 complex organ systems are needed, not 58 or 69 but all 70 must work together simultaneously at one time or the person will die.

Therefore the human body can only be a creation and not a gradual development from a single cell. All humans need to take in oxygen including fetuses, so the development of the respiratory system had to happen suddenly at at once for it to work at all. So there could be no partially developed humans around with some of the organ systems needed because without all 70 complex systems fully working e.g., respiration, these or any humans couldn't exist."

(Note: 70 is surely the wrong number. I chose it only to illustrate the parallel with the original post. The actual number is irrelevant.)

What are the 70 chemical reactions you speak of? I'm ignorant and wish to learn (and you do know, right?).

Photosynthesis did NOT develop in plants.
It developed in bacteria, specifically purple bacteria. The chloroplasts in plants are actually symbiotic organisms, the direct decendants of the original bacteria. Chloroplasts have their own DNA. In some algae it is apparent that some kind of intracellular symbiosis occured several times, as they have chloroplasts with mulitple layers of double membranes - each with a small set of DNA (up to 7 such layers)..
Photosynthesis occurs when a chemical reacts with light, absorbing the energy of the photon and storing it. This kind of thing happens all the time in simpler forms. It is by no means a stretch to conclude that simple photochemical reactions could evolve into more complex ones.

 

Some of those simpler forms of photosynthesis still exist today

And you know because you were there, right?

Personally, I think it evolved in cyano-paisley-bacteria first, but I was born a few million years after you, so what do I know?

 

[Late_Cretaceous]

Nick, thanks for the valuable contribution to this discussion. I accept, as does the scientific community, that photosynthesis originated in bacteria. This conclusion is based on the accumulation and anaysis of evidence. It is possible that further evidence could point to different origins for plant photosynthesis, and that would be quite dramatic.

 

[chickenman]

what do you know? very little

the old "you weren't there" claptrap

some say humans built stonehenge, but we weren't there, so i guess it could be very large rabbits, or very many ants. Possibly even some sort of mythical troll like creature with 8 arms and 3 noses. Who can say?

 

[lithium.]

lol this thread is really funny, i can't even think of anything to say other than that Evolution and Photosynthesis of plants are very weird but i want say i understand it all, i only know that plants have been around for millions and millions of years, so you know there doing something right hehe.

 

[DNAunion]

DNAunion: We also need to keep in mind that not all photosynthesis is the type people seem to be discussing (as if it were the only type that could exist) -- there is also anoxygenic photosynthesis.

As far as the list of 70 "chemicals", does this include BOTH photosystems I and II? If so the list is invalid -- both photosystems are not mandatory for photosynthesis to occur: some organisms get by with just one of the two.

 

[MSBS]

Hmm...how about some of the other non-chlorophyll photosynthesis systems. Do they get included in your IC argument, or did they evolve?

It's funny how the IC arguments have "evolved" over the last couple of years.....from the old "half an eye is useless" to the complex biochemical pathways....I wonder what it'll be reduced to 20 years from now? It sure will be fun to watch.

 

[LadyShea]

Not all living things are part of the oxygen cycle. Several species of extremophiles use other chemicals for energy...and manage to thrive in environments deadly to all other known lifeforms. If you wish to debunk evolution, please look at all possibilities
