Friday Whatsit for January 21, 2011

January 21, 2011

What is it?

What is it? Click to make giant size.

This week’s Friday Whatsit is another cell structure question.  What is the cell structure highlighted in green?

Hint: its featured in the Harvard University / XVIVO Inner Life of the Cell video at about 1:07.  They are shown growing, dissolving and then acting as highways for transport vesicles.

Some of you have had the right answer on this kind of post in the past and didn’t guess for fear of being wrong.  Just go for it!  If you’re right, you’ll win legions of adoring Tiny Science fans (well, maybe that’s an exaggeration). But I can assure you, if you’re wrong, no one will show up at your house and point and laugh.

Leave your guesses in the comments section, answer on Monday!

    I thought it looked like a supernova remnant dyed green at first…
    but that’s a little big to live in a cell.

    • Little bit, yeah. Besides, why would you dye a supernova remnant green?

        I dunno, why do squishy scientists do anything?
        Crazy biologists…
        Dying pretty pictures green

    It is an inner membrane pore of a mitochrondria organalle (from Mark, NOT Whalegeek). Or in lieu of that being the case M suggests this looks like a fluorescent green hornet’s nest. Whalegeek thinks it is the Creature From The Black Lagoon, up to no good yet again.

  3. I have been absent for some time, but now I remember why I used to love this web site. Thanks , I will try and check back more frequently. How frequently you update your web site?
