Quanitative Differences

I took a picture of the Lily of the Valley flower. To qualitatively analyze this plant, I would count the amount of flowers and propagate the ones that had the most to eventually increase the yield of flowers, which would be very useful for a florist and profitable.

Node sizes.JPG This is a bamboo shoot that I have in my room, and if you can tell, the nodes are a slightly different size. The node size here is a quantitative trait.

AK_Qaunatitative: Initial Shoot Formation

quantitative diff in initial shoot formation.JPG
These are a few purple onions that were sprouting in my vegetable bowl. The quantitative trait here is the number of initial shoots formed. Initial shoot formation for these onions (and the other two I found sprouting) was between three shoots and eight shoots. With only five specimens it is difficult to determine whether this trait is actually quantitative or qualitative. The shoots came up in clusters of three or four, with onions have larger number of shoots showing them in such clusters of three or four.

Orange slices! Unfortunately, I did not know this orange would be seedless. Purchased at the convenience store, an orange from Texas. Fruit chosen for how cool it looks sliced.

Milkweed pod, in front of the Bell Museum, photo taken some weeks ago. I like this photo for the beetle crawling around and the color.

Week 10 Assignment

I could not find a fern now, the ones by my house are dead, so I found a picture of ferns I took at my cabin last summer. You cannot see the sori, but this picture gives the general idea for the morphology of a fern.

In the upper right you can see a green moss on the bark of a dead birch. You can see the gametophyte and the sporophyte (the brown 1" stalks). I wish I had taken this picture with a zoom.

Week 8--fall colors and photosynthesis


I thought it was interesting that this tree with the red leaves was red, only feet away from one that was almost all yellow. I wondered if the different species just had a different allocation of pigments. I also took a picture of a tree with a small callus growth at the bottom down my street.

October 27- fall Colors

Fall Color.JPGCallused.JPG In the first image, you can see the difference in the colors of the leaves that were facing away from the building. In the second photo branches were cut down creating calluses on the trees.
