why don't you just find a good site which explains it well pete rather than expecting a long answer from someone here. google can help you learn almost anything.
Pete, there are a lot of differences between plant and animal life cycles that are too involved to discuss here, but for the most part, animal chromosomes and plant chromosomes are the same. That is, they're made of the same stuff (coiled DNA and proteins) and they look the same, replicate the same way, etc.
The difference is that they have different genes, of course, which is what makes plants plants and animals animals. I believe they lack X and Y chromosomes, and the number of chromosome pairs varies with every species.
Besides genes, the largest difference is in the reproductive cycle of cells. Humans are always diploid, and only the sperm and egg are haploid.
Plants are different, though, and part of the time they grow as haploid organisms, then mate and become diploid. It is quite confusing and flowering plants do it differently than non-flowering plants, and I can't remember any of it, but I suggest looking it up if you're interested.
Also, in terms of chromosomes, plants tend to handle polyploidy (too many copies of chromosomes) better than humans. Many plants are 3- or even 4-ploid. In humans, this wouldn't happen.
The list goes on, but I'm sure it's stuff you can discover on your own. :icon14:

Thanks, I did a quick search on it.
Is the cell walls then acting like a captured light energy from the sun...Analogy...as a house with power solar energy panels...
Plastids are organelles that are able to produce carbohydrate compounds. The most abundant and most important of the plastids is the chloroplast. Chloroplasts contain chlorophyll. This compound, chlorophyll, is the means by which the plant converts sunlight into energy for use, in the form of carbohydrates.

No. Cell walls only serve to keep the cell rigid, and to protect the integrity of the cell. All the metabolism takes place inside the cell, as you said, in the chloroplasts.
We all know that plants need solar energy or at least some source of light...Do you know, read something about if, it would be feasible to replace that energy by plugging electrodes like, one on its stigmat an another one to its root from a source of electricity and it would grow even in the dark.

STFU retard, all of a sudden you can't read english?
Mon ami tu te rappelles que je suis french canadian comme toi.
Je ne connaîs pas tous les mots anglais. Ni STFU retard.
Pete
Yeah whatever retard, whenever anyone EVER metions anything remotely insulting, or about you being an alt you respond the same way every time, like you don't know wtf we're talking about but you're doing research on chromozones.
If you weren't full of shit, I wouldn't mind you, it's the act that's annoying.
What hey are speaking of about the plained buisness is that a member awhile back could not speak English all that great, he made us all el oh el all the time with his grammar. He hasn't been around much after the change from raw-one to q3w so they are thinking you are the said person.
I on the other believe otherwise, like you said...you are a 47YO frenchie.

I guess that could be a possibility, but I doubt it would work. Chloroplasts absorb light with specific wave-lengths to excite electrons in the chloroplast. It's been awhile since I've taken either botany or quantum mechanics, but electricity would only send electrons through the plant, which is not what we want. Without electrons properly excited, sugar won't be created.
Also, I'd expect electricity to throw the electron transport chain out
of whack, but that's a whole different topic.
