Chlorophyll~~ breathing light

18 Aug


 Chlorophyll: breathing light. There’s your post title. Now write! Never go past a word not understood… Defining will help:

chlo·ro·phyll  /ˈklôrəˌfil/

A green pigment, present in all green plants and in cyanobacteria, [a division of microorganisms that are related to the bacteria but are capable of photosynthesis.] responsible for the absorption of light to provide energy  for photosynthesis. [the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. ]  Its molecule [a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.] contains a magnesium atom held in a porphyrin ring. [Any of various organic pigments containing four pyrrole rings bonded to one another. The rings form the corners of a large flat square, in the middle of which is a cavity that often contains a metal atom. Porphyrins occur universally in protoplasm and function with bound metals such as iron in hemoglobin and magnesium in chlorophyll.]

When we see with the body’s eyes it makes sense that this is what is helping humanity to see the things we agree upon as reality. I hadn’t thought of this until looking up the definition of chlorophyll.

In this video we will explain the color changes leaves go through each fall, demonstrating how plant dyes change in concentration with a leaf chromatography experiment. Mikhail Tsvet originally performed this experiment in 1901, and we’ll be performing a modern-day version that viewers can perform at home. Our video will be told through the perspective of Chlorophyll who will narrate the video. We will begin by discussing and diagramming how plants make and store food through photosynthesis, explaining the concept of chlorophyll and its green color. We will then show how seasonal changes cause trees to decrease food production, reducing chlorophyll and revealing/enhancing the other colored dyes already in the plant’s leaves. Next we will demonstrate these concepts by performing a chromatography experiment on screen with several different colored leaves. This experiment will be done with everyday materials such as a coffee filter, pencil, and rubbing alcohol. We will explain how fluid wicking and gravity allow us to see the different concentrations of plant dye and suggest the viewers try the experiment again other dyes such as ink from markers. We will then demonstrate how much fun can be derived from fall leaves by having a massive leaf fight. is their fb site : )

Time for Me to Leaf: Tree Chlorophyll Chromatography

Why do leaves change color each fall? Do this experiment to learn about different pigments in leaves.
