Question about mitochondira

Postby asutoshsahu » Tue Jul 12, 2005 2:06 am

why green plant cells contain less no. of mitochondria as compared to non green plants

Please clear my doubt if any one knows.

the only one solution may I find at the moment is: green cells do have chloroplasts and so, they can produce some kind of energy in them. That's why they need less mitochondria than nongreen parts of plant, which must produce energy they need ONLY in mitochondria.

I am not a botanist bu I ever heard about this case. Maybe this explanation help, that's all I ever read.

It is because green plants synthesize their nutrients for their energy from processing anorganic materials via photosynthesis. They equipped with many chloroplasts that able to absorp proper lights to undergo the process. That's why they do not need more mitochodria.

In nongreen plants, they lack chloroplasts so they need another powerhouse to undergo the process to generate energy. That's why they equipped with more mitochondria. But, not all nongreen plants have more mitochondria campared to green ones. Some nongreen plants have small number of mitochondria, because they still able to do photosynthesis, without chloroplasts but chromoplasts, for instance carotene, xanthene, etc.

It's just like endosymbiotic theory.."smaller cell loose some of its organels because what it need is already supplied by the host"
Q: Why are chemists great for solving problems?
A: They have all the solutions.

About endosymbiotic theory, when I read for the very first time about the coming up of mithochondria, it sounds like a fairy tale for me hihi :lol:

Are those without chloroplasts considered plants?

There seems to be something wrong with both those hypotheses. First off, plants cannot use the energy captured from the sun and use it for respiration purposes; the energy is used to make glucose. Since eventually the plants will have to metabolise the glucose anyway, wouldn't the number of mitochondria be the same?

All plants have chloroplasts. Even nongreen plants also have chloroplasts but they also equipped with chromoplasts, which is their number is much more than chloroplasts so this condition results in nongreen in color but depends on the dominant chromoplasts that exist.

I not quite understand that you said that all plants have chloroplasts. So how about fungi?? They have chloroplasts or not???Are you sure about this?

Well, a fungus is not a plant, it's in the fungus kingdom.

There are plants which don't have chloroplasts or chromoplasts. I don't remember its name now but I've seen one in my plant bio. book. An ugly white thing. :P

And yes, fungi are not plants. :)

Hmm, I just read our dictionary interpretation, I don't like how it's saying plants includes fungi.
