My main questions involved trying to discover the most integral parts of biology and bioengineering; I wanted my question to revolve around what it truly meant to be alive I wanted this question to not involve human species, but the species that provide us with the necessities of life-plants. My question was: How do you know when a plant is alive?
I looked a tree to examine whether or not it was alive. I assessed a leaf that was still attached to a tree to observe its structure. I also looked at a leaf that was a faded brown color, and assessed its colors and structure. While in the field I also looked at what appeared to be an infected leaf, and my curiosity to see whether or not it was doomed for death as well. A small piece of each leaf was scraped off using my fingers and placed on the slide. A clear covering was placed over it to make a miscroscope slide. Using the Foldoscope and my phone, I aligned my camera to the center of the Foldoscope’s opening, and recorded my observations.
Alive Leaf
Infected Leaf
Dead Leaf I can clearly see that the leaf attached to the tree had a bright green coloring, with very clear pores that let light in. The Infected Leaf looked to be deteriorating, with smaller separations between the cuts and red spotting. The Dead Leaf still had a similar pore structure, but had an overall brown coloring and multiple black spots. Some final questions I had: Does the redness on the leaf affect it’s growth rate? What makes particular leaves fall naturally?
