Alga reproduction
Alga reproduction
Plan 40x/0.65, DIC, alga is 280µm length, stacked and stitched in Photoshop, Marine sample, Alboran Sea.
Not sure what to call this stage of the reproduction process ... germinating carpospore?
Note what looks like a crystal inclusion.

Re: Alga reproduction
Here are a couple of photos of the same type of filamentous alga*, one with the Carpospore still attached and one showing more inclusions.
*These were taken from the same slide but somewhat later for context. Slide had mostly dried out by then (had to add a fair amount of water), which is why everything looks a little worse for wear.
Interestingly, the inclusions seem to be concentrated towards the ends of each alga segment.

Re: Alga reproduction
Is that a red algae? Your DIC images are amazing.
Re: Alga reproduction
Thanks Sauerkraut, I have not managed to ID the alga yet.
Also can't seem to find anything on crystal inclusions in algae other than Calcium oxalate, which it says are transparent!

Re: Alga reproduction
I really like these images although I'm not quite sure what I'm looking at exactly. The thin elongated structures, are those individual cells?

Re: Alga reproduction
Thanks Wes
Will post when I have some news
I am still trying to ID the alga, if manage that I will hopefully then be able to find out how it reproduces and what bit does what. Some info on the crystals would also be nice.The thin elongated structures, are those individual cells?

Re: Alga reproduction
Excellent, and as Ed' says, a touch of mystery.
I found a good link re carpospores and indeed the life cycle including the carposporophyte...
An image from about 60% down the article's page,
Very interesting, not to mention superbly-crafted images 75'!
