Blizz_rb93:
This is a question about Daphnia

- Suggest why Daphnia needs a heart and circulatory system?
the rest of the daphnia questions i know but this one i didnt know lol

nid404:
Is there anything special about daphnia?

As far as I know organisms require a heart to act as a pump and enable efficient transport of substances like nutrients and respiratory gases for cells.

Also, what i can figure is a heart and circulatory system in required in this case, cause maybe the surface are to volume ratio of daphnia is not high enough to allow exchange of substances on its surface. So, an internal system is required

Maybe I can help more...lemme know

Blizz_rb93:
Oh okay i see
thank you nid!! :D

nid404:
No problem...

I'll study the daphnia a lil more in detail...if i get to know anything more..i'll put it up here  :)
