Plants Perform WorkIn this experience, I first set up my sample site in an open area and wrapped 20 grass leaves with aluminum foil strips. I clipped a piece of grass each day when it has received half a day of sunlight and later a full day of sunlight. I recorded each clipping individually and raised the contrast to analyze it better. The clippings were drying up after a day, so keeping records of individual one after each cut was most effective. After raising the contrast and placing the pictures of each day side by side, I noticed that the grass was getting discolored as the days grew. It was apparent at first, but there were lighter spots and lines in the grass after a few days. This may because the aluminum foil is preventing the grass’s efficiency in absorbing sunlight. The chloroplasts in plants makes it green, and since sunlight is needed to produce chloroplasts, the grass are experience discoloration due to lower sunlight absorption.

Questions
What would happen if we couldn’t store energy?
Our body uses food energy to sustain life and burn stored energy to do different activities throughout the day, such as breathing. If we can’t store energy, we wouldn’t be able to function properly and will eventually die.
When you burned different foods in lab one, you saw what happens when the energy in a food item is essentially all released at once. What would happen if this were true of the food we ate (not the burning part), but the very quick release of energy?
If food energy is released quickly, we will be hit with a boost of energy and then crash afterwards. We would have to eat more food to have energy to last the day because the energy isn’t stored to sustain the day but released too quickly.

Edited under contrast since grass dried up after a day. Pictures of each grass clip was recorded after each fresh cut and put together at the end for a better visual.
