Resilience - Shine On!

Plants can turn to face the sun, capture this radiant energy, and fuel the entire ecosystem.

Plant Science Concept:

Plant cells contain unique organelles called chloroplasts, which contain pigments, including the green pigment chlorophyll that absorb the energy of sunlight. This energy is used to split water molecules, producing a negatively charged particle, called an electron which is funneled through the chloroplast membrane (called the “electron transport chain”). At the end of its journey, the negative energy is transformed into usable energy (called “ATP”) and reducing potential (in the form of “NADP+/NADPH”) that is then used to convert carbon dioxide into the fuel and building materials necessary for all plant growth, development, and defense. As an added contribution, this near-magical alchemy also produces oxygen (as a waste product!) that enriches the air we breathe and makes most life on earth possible.

Horticultural Applications:

Provide plants with a suitable amount of light and water to carry out photosynthesis. Water not only provides the electrons needed for electron transport but it also regulates leaf temperature through “transpiration”. This happens since liquid water vaporizes as it exits the leaf, creating a cooling effect. Be sure to provide enough water to allow plants to maintain temperatures needed for metabolism during periods of drought and high temperatures.

"Every plant and human has a uniqueness that they can bring to the world. No plant or human is exactly the same as the other. We all have quirks, and even talents that can be put to use. According to Native American folklore, the sunflower was once a star that fell to earth, and became a symbol of hope and resilience. The sunflower's bright yellow petals were said to shine on even in the darkest of times, serving as a reminder to keep moving forward and never give up. If we give up, we can never learn and grow from our mistakes, or natural challenges of life. We must prevail in all circumstances, and continue to thrive with the hand that we have been dealt." ~Jack Stanis, B.S. Wildlife Conservation, Class of 2024
