Field Notes
One of the hardest things to do was to get a picture of the cells and to make sure that there was enough water but not too much. Somethings that were exciting was to see all the different cells in different plants also to see how thin and thick some branches were and last of all to see how they branch out. My research was very adventurous because you learn new things as you go like learning about all the different cells in different plants, also we got to look at Dasysiphonia and we had to try an find it too.
Supporting Evidence

This picture is at a 40x magnification. I think this is not Dasysiphonia because I don’t see any shepard hooks. Also if you look at it at a higher magnification than you’ll notice that it doesn’t have single cells.

This picture was taken and looked at, at a 100x magnification. I think this isn't dasysiphonia because it’s not single celled all the way to the tips of it. Also there are no shepherd hooks, and Dasysiphonia can branch like this one but it has way to many cells in it.

This slide of a plant from Little Machias Bay was at a 40x magnification. I don’t think this is Dasysiphonia because it doesn’t have single cells to the tip. It also there are extra weeds connected to it and it doesn’t have any shepherd hooks. Also has a dotted line through the middle of the branches which Dasysiphonia doesn’t have.

Was there an obvious midrib - kind of like veins on a leaf - on this seaweed? It looks like Membranoptera to me.

Thanks for your help with this!
