>> Humans depend on plans for survival. They help provide us
with food,
medicine,
oxygen, and so much more
and plant survival depends on one incredible natural process.
Photosynthesis, here's how it works. Photosynthesis is a
chemical change that happens in the leaves of green plants in
which the plant uses the energy from light to make its own food
source to perform. Photosynthesis plants need 3
things, water, carbon dioxide and sunlight.
>> The plant takes up water from the ground through its
roots, pulling it all the way up the stem and ultimately
storing it in the leaves to be used when photosynthesis
begins. The leaves also have tiny holes that can take in
carbon dioxide from the air. These steps provide the raw
materials needed for photosynthesis. And the whole
process of photosynthesis is triggered by the energy from
sunlight hitting the leaves. The sunlight excites. The
plants chlorophyll, the national pigment that makes
them green. The water from the roots split into oxygen and
hydrogen. And the oxygen is released into the atmosphere.
The hydrogen bonds with the carbon dioxide from the air to
make the coasts, the food plants. So this Earth day,
take a moment to stop and smell the roses or just marvel at any
plant. You see the process that keeps them alive is pretty
incredible. And the key to our survival, too
