The Origin Life – A Science Discussion
First, if you haven’t already, go to the page – Preparing to Post to THE DISCUSSIONS , and do what is required of you. Then, come back and DISCUSS. The link will open in a new window.
In science class you recently learned about the Cell Theory. One of the important parts of this theory is that living cells can only come from other living cells. A phenomenon we like to call “like comes from like”. However, my young, bright students brought up a valid question: Where did the first cell come from? Obviously life had to start somewhere! Using what you know about cells, chemical interactions, your knowledge of what makes up all matter and living things, and possibly even research on the topic, discuss your ideas and theories in response to this question. Please be respectful, literate, and use acadmic vocabulary in your response.
Where did the first cell come from?
Please refer to Mr. Moshé’s rules for posting. All comments are strictly moderated.
I think the first cell came from a chemical reaction, or a grouping of organelles. Which then mutated of some sort with something else causing more cells to duplicate creating bigger living things.
I think that the first cell was created by atoms.
I agree with David and Ryan, that the first cell came from a chemical reaction. Once this happend and the first cell came to be the started reproducing very quickly.
I think that the first cell came from the first person or plant on the earth. They are living and you have to have cells to be living in my case. Now you can have cells that are dead but you have to have cells. That is where the first cell came from, the first person or plant.
I (like a bunch of other people) think that the first cell came from a chemical reaction. As seen in Mr. Thomas’s warm-up video, the little guy that moves the vacuole across the bridge thing, does not have a brain. So the only explanation for his movement is a chemical reaction. All a cell is, is just a bunch of chemical reacitions creating a function. Now of course a cell couldn’t have formed over night. Evoulution had to take it’s sweet time, creating cells. Making sure that they were the perfect base for life.
It’s either that, or Chuck Norris was bored one afternoon.
i think when the earth was created the cell was created at the same time. i mean not all of us know exactly how the earth was created so we don’t really know how the first cell was created. however if i were to guess, i would say that atoms came together at random and formed a cell.
I think that the first cell, like many others said, came from some sort of chemical reaction. The organelles were created through the reaction and formed the basic unit of all living things, a cell. Then the cell reproduced and made other cells and those cells made more cells, and so on. But, the cell theory says that only cells can come from other living cells so I guess we don’t exactly know for sure.
i have reason to believe that the 1st cell came from a chemical reaction within the grouping of organelles. After that other cells came from that cell and the process continues over and over and over and over again.
I agree with Kathie T, I think that it came from a chemical reaction. There was probably a nucleus at first, and then it developed into a cell. Then that made other cells and it became tissue then it became an organ then it became an organ system then it became an organism.
I think that the first ever cell came from some sort of chemical reaction, so I agree with all the other people who think the same thing. Once that happened, the cell was created and reproduced, and that cell reproduced, and so on because like comes from like. Cells can only come from cells, and soon there were tons and tons of cells which all had a different functions which lead to what we are today.
I agree with Jenna that the first cell came from a chemical reaction. During this reaction they formed organelles which then became a cell. Then the cell reproduced and made tons of other cells that formed some sort of organism. Years later that organism’s DNA got mutated and evolved into something else. This happened many many times and then humans were a result of an evolution.
I think that cells were made out of atoms and they just started reproducing in to many cells.
Since I am to explain in scientific terms, that doesn’t involve a supernatural being that controls all life as we know it, I’ll use the more common theory.
Apparently the first cells came from this condensing ball of infinite density and mass that collapsed and exploded outward allowing only the simplest atoms to be formed and stay alive. Those atoms kept building onto each other to form new, different atoms. Then after billions of years of connections, reactions, and more explosions, a few atoms linked together to form what I’m guessing is a stem cell (being these can turn into many types of cells). These stem cells multiplied and multiplied and in the time we have come since Precambrian have gotten us this far.
I think the first cell came from outer space. A meteor that came from somewhere far away could’ve contained a singled celled organism. Or the meteor could’ve contained a certain chemical that bonded to a chemical on earth to create a cell.
I believe that a cell originated from God because of my beliefs, though from a different perspective, during the paleozoic era, the Earth was nothing but water. In order for there to be water, there must be some type of atom present. So after the long period of time that the Earth was occupying space (which could’ve possibly been longer then what is beleived to be the estimated time by scientist) before the paleozoic inhabitants were introduced, a chemical change took place involving atoms constantly combining into a molecule. Eventually after a continued process of atom combinations, a cell was created.
I honestly cant answer that i would have a more biblical answer because i learn science but dont always believe in it so i would have to say the first cell came from a chemical reaction probably with what chemicals maybe hydrogen and oxygen

I think that the cell came from existing atoms that chemically formed with a reaction that ended up with the cell. Just like how two chemicals react to make something different, those two different atoms reacted chemically and formed the cell. The end 🙂
