A form of energy that comes from photosynthesis is ethanol. Ethanol is made by sugars and starches and is used in automobile fuel. Human need oxygen made by plants for survival and we make carbon dioxide that plants need for photosynthesis. Our lives rely in the results of photosynthesis.

Photographs appear of a plant and the sun. Photosynthesis couldn’t happen without the sun. Plants collect energy from sunlight and use this energy to make sugar called glucose. 

(Glucose). Glucose is the main source of nutrition for plants, fueling their cells for function and growth. 

How? I’ll show you. The roots are submerged in water, then the roots drink up all the water. It’s no secret that plants use their roots to drink up water from the soil. 

The interior of a tree limb reveals cell-like tissue.

 Water travels from the roots to the plants’ leaves through a transport tissue called xylem—that’s wood in trees. (Xylem) Meanwhile, leaves absorb carbon dioxide from the air through openings called stomata. (Stomata)

An “stomata,” as green tubes.

Many cells line the inside of a leaf, shaped in rectangles and irregular circles. The water and carbon dioxide spread through the leaves into cells called palisade and spongy cells. 

Water seeps into the cells inside the leaf. (Palisades and spongy cells) These cells contain structures called chloroplasts, which are filled with a green pigment called chlorophyll. 

The inside of a round, green cell contains many stacked cells. (Chloroplasts and chlorophyll)

A tree and leaves that cleaning their carbon dioxide. Chlorophyll is what makes green plants green.

A leaf receives the sun’s rays. In photosynthesis, chlorophyll traps energy from sunlight, storing it as chemical energy.

Two hydrogen atoms and one oxygen atom, forming a water molecule. This process splits water molecules into hydrogen and oxygen atoms. 

Two ATP molecules blast and tear apart the atoms of the water molecule. 

Many ATP, hydrogen, and oxygen molecules float free. The chemical energy is used to create glucose from the hydrogen and carbon dioxide. After, the molecules are joined together. The glucose dissolves into extra water molecules and gives the plant plenty of food for growth. 

A green plant releases white molecules. The leaves release oxygen as a waste product. Well, that’s one reason that plants are so important to us. Explain: A dog inhales a plant’s oxygen and exhales carbon dioxide. The plant absorbs the carbon dioxide then releases the oxygen. An arrow circling from the dog to the plant indicates that this is a continuous process. Plants, animals, carbon dioxide, oxygen. They absorb our carbon dioxide and leave us with oxygen. We inhale the oxygen and exhale the carbon dioxide back into the air. That we can countiunes alive with fresh air (OXYGEN)
