E-Portfolio Assignment
By: Ashleigh LeBaron
For my e-portfolio assignment, I wanted to show how photosynthesis relates to my life.
So to start off, what is photosynthesis? Well, the technical term (according to dictionary.com) is:
the process by which green plants and some other organisms use sunlight to synthesize foods
from carbon dioxide and water. It generally involves the green pigment chlorophyll and
generates oxygen as a byproduct.
And why do we need it? Because photosynthesis is the reason we are all alive! It provides
energy to help the world’s plants to grow, giving us food to eat and oxygen to breathe. It
provides food to the plants, which eventually brings about the creation of oxygen. Oxygen is
needed to get the most energy from that food, turning it, ultimately, back into water, carbon
dioxide and energy, which keeps everything on the world growing, breathing sustaining, and
surviving.
Almost all the life on earth depends on photosynthesis. If it wasn’t for photosynthesis all
of the life on earth would cease to exist. We wouldn’t be able to breathe without it. No
photosynthesis means no plants, which leads to no air, ending up in the extinction of all human
kind. We wouldn’t have to worry about “global warming”, world hunger, war, poverty, or
anything like that because we would all be dead.
So it is a huge deal in our lives that photosynthesis remain. And that is how
photosynthesis relates to my life!
