Millions of chemical reactions + processes in every plant:
Every moment - inside uncountable amounts of cells
Photosynthesis is the most important
light-dependent reaction on Earth!
Everybody knows what a leaf looks like ...
Without Photosynthesis would be NO oxygen on Earth!
What would happen if we breath without getting oxygen?
But did you ever think about how a leaf looks inside?|
You will be surprised!
There are different parts of a leaf involved in photosynthesis
Mostly we think about green leaves, but most of leaf cells, the cell material have no color.
When we see green, we see the chlorophyll molecules in the chloroplasts
Chlorophyll inside a leaf
In a leaf are many different types of cells, each cell for a different task
All these cells are needed - a perfect plan for life
Scientist name these layers:
Top = cuticle layer + epidermal cells
Middle = mesophyll cells with the chloroplasts
Bottom = cuticle layer, epidermal cells, and stomates
The function of the stomates is to regulate the input and output of carbon dioxyde CO2 and oxygen O2
Let's have a look at the Mesophyll Cells
Two different mesophyll cells are in a typical leaf.
Many in the palisade parenchyma region others in the spongy parenchyma region.
Look at a chloroplast: They are tiny, but you can see them under a microscope.
When we look what is inside a chloroplast we will see the stroma and the grana.
That's where photosynthesis happens
The outer layer of the thylakoids are home to chlorophyll and other pigments. Photons, sent out by our sun, hit the pigments and electrons are getting loose to provide the energy for the complicated process of photosynthesis.
Often we hear the word photosynthetic membrane describing a thylakoid.
When you look at these flat pancake shaped pieces, scientists call them thylakoids.
A stack of thylakoids is a granum / plural grana
You see the hose-connection? The name for these connections is stroma lamellae.
The membrane and the space inside it, is where the light-dependent reaction takes place.
The light independent reactions happen in the stroma.
Chloroplasts are carbohydrate factories using sun light as energy.
They have their own genetic material, they can multiply!
As working materials chloroplasts need:
These raw materials allow the chloroplast factory to produce food for the plant,
plants all mammals need for food, for oxygen!

When plants photosynthesize, they use energy from sunlight to turn carbon dioxide from the air into sugars used to live and grow. In doing so, they give off a fluorescent light — a glow that can’t be seen with the naked eye, but that can be seen with the right instruments. More photosynthesis translates into more fluorescence, meaning that the plants are very productive in taking up carbon dioxide. The amount of carbon dioxide taken up by plants is called “gross primary productivity,” and is the largest part of the global carbon cycle

without plants, without oxygen?

It is very important to protect Nature!
A) Plants on Earth balance our climate
B) provide oxygen, change carbon dioxide
C) store carbon dioxide CO2
D) provide food and protection!!
