Today I am going to give you a photosynthesis
simple explanation.
Basically because that’s all I know is a
simple explanation.
I thought it would be useful for me when I
was studying gardening initially to know the
basics.
And so that’s all I know, and that’s all
I need to know as a gardener.
So you have your plant, a very nice plant.
It has nice green parts, it has leaves, and
photosynthesis takes place in all the green
parts of the plant.
So if you have herbaceous perennials, even
the stems can be photosynthesizing, but the
leaves, that’s really what the leaves are
for.
Then you have below ground beautiful roots
and they are necessary to take up water which
is where a lot of the water from a plant comes
from, the underground.
So water is needed for photosynthesis, that’s
the first thing.
The second thing would be some air.
Really it's carbon dioxide that the plants
need.
They’re taking carbon dioxide and they take
in carbon dioxide all throughout their body.
They will take in carbon even in their roots
so it’s not only from the air, but that’s
carbon dioxide (CO2).
And then they need energy and the energy comes
from the sun, comes from the visual light
spectrum, the same thing we see.
Energy comes down here and that energy allows
the chemical reactions to occur, and so there
you go.
You’ve got your water, your H2O, and 
then you have photosynthesis.
So carbon dioxide, water, energy makes it
all happen and then what happens?
Well, basically that oxygen is given out again,
which is why I can breathe.
That’s all I need to say there.
And then a little bit of water is given off
as well during this process.
It’s worth while saying that.
It comes out from the leaves and then the
carbon goes into the plant and the plant gets
a little bit bigger.
And basically, it's sugar that it creates
- carbohydrates, various kinds of sugars.
And this is really how a plant eats.
This is how a plant gets bigger.
You know what else it needs, it needs a little
bit, like maybe 5%, a little bit of minerals
from the soil - proteins, minerals - and so
it’s gonna take those up.
And they’re almost like a catalyst, a little
thing that’s needed to make this whole reaction
happen.
And so that is how a plant eats and then it
grows and it gets bigger.
It does this all on its own and so then this
is how I get huge muscles because I get to
eat the plants and so does most everything
else.
Most organisms on the planet rely on this
photosynthesis whether they eat plants directly
or whether something comes along and eats
me, ultimately it's relying on that photosynthesis
for food.
So plants are pretty amazing and that’s
all I wanted to do is give this photosynthesis
simple explanation.
I hope I didn't jump all over the place too
much.
