Anyone have a picture of a mitochondrion in a ovum?

 

I can't find one. I'd probably have to search for hours/days for a picture of one in some journal. Otherwise, I don't think I know where I could find a picture of a mitochondrion in an ovum. Hence, I tried Google.

 

If you know of a journal article that shows an obvious mitochondrion in a gamete, that will work, too.

Is this any good?

Yes, well done.

Of course, I'm a fool.

 

I should have stated that I'm trying to find an image a mitochondrion in a mother's gamete, such as an ovum. There is such a thing, right?

 

* note: original post has been edited to say "ovum" instead of "gamete."

From what i can tell, i don't think there are any mitochodria in the ovum cell itself.

I didn't think there was.

I'm reading about cytoplasmic inheritance again and endosymbiosis.

I could be wrong.

Are you in AP Biology? Thats the chapter we just finished.

No, I'm not.

No, I'm not.

 

never mind then, lol

Huh? Of course the ovum has mitochondria. That is why mitochondrial DNA is almost exclusively inherited by the mother.

You see, that's what I'm reading. Yet I have not found a picture proving such a case.

When I don't seem to have physical evidence proving the fact, I tend to generate fuzzy ideas about what I'm reading.

Got any decent ideas where I can find one, CharonY?

 

p.s.

 

Thanks for the affirmation, CharonY.

Here's a couple of images of mitochondrial DNA

That's not what I'm aiming for.

I want to see it in an ovum gamete.

Thank you, though.

Take a look at the drawing there (fig.1) the bottom is part of the oocyte. You can quite clearly see inclusion bodies including mitchondria there.

Excellent.

Thank you.

 

So, it's safe to assume there is more than one mitochondrion in an ovum cell at one time?

Pg. 17 seems to show miraculously many mitochondria is some static situations.

These mitochondria are marked "m."

 

p.s.

 

How did you go about finding that?

Pubmed, I'm guessing. Any keywords you used to unlock such a document?

Of course there are more. They require quite some even for energy conservation. Once fertilized they have to grow rapidly. The energy has to come from somewhere.

Searching for it is quite easy. Just look for oocyte and maybe electron microscopy and pick out the oldest article you can find. Nowadays you hardly see basic cell descriptions in papers anymore as they have become common knowledge. The alternative is to open a nice cell biology or cytology book.
