14/20


15/20

A general statementPhotosynthesis is a food-making process that occurs in green

plants. It is the chief function of leaves. The word

photosynthesis means putting together with light. Green

plants use energy from light to combine carbon dioxide andwater to make sugar and other chemical compounds

Sequenced Explanation

It works into two stages : The Light Dependent Reaction and The

light Independent Reaction. In Senior High School, generally

known as Aerob Reaction and Anaerob Reaction.The First stage is The Light Dependent Reaction. In this first step

of Photoshnythesis, sunlight enters the first Photosystem and

energizes the Chlorophyll.

The excited Chlorophyll splits water into Oxygen and Hydrogen.

Meanwhile, the chlorophyll feeds electrons into a complex

sequence of nearby molecules called the electron transport chain.

The freed Oxygen escapes into Athmosphere, While the freed

Hydrogen is used later in The light Independent Reaction.

As electrons move along the electron transportchain, their energy make the moleculeATP, which is used by all known forms of life to fuel their cellularfunctions.The electrons enter a second Photo system, get full energized by sunlight, and movealong another electron transport chain to construct a molecule called NADP.The second stage is The Light Independent Reaction. NADP combines withHydrogen, which was freed earlier in The Light Dependent Reaction, to produceNADPH.NADPH, ATP, and Choloroplast Enzyme called Rubisco, work together to createsugars and other Carbohydrates from Carbon Dioxide and Water in a ProcesscalledThe Calvin Benson Cycle. It is a very complex reaction that Fixes arbon fromthe Athmosphere forming The Foundation of Earths major food chains plantsdirectly use sugar as their food, and many other organisms eat plants to gain theirstored energy.

ClosingWe can also conclude that Photosynthesisis how plants use light and water to makesugar and It is created in the green partsof a plant and every animal on earthdepends on it. So, Without plants wewould have no food to eat or oxygen tobreath.
