Photosynthesis - The cycle of plants and how they make energy!

The sun(light energy), water, minerals and carbon dioxide are all absorbed by the plant.

This process is known as carbon fixation or the Calvin cycle.

The Calvin cycle has three main stages: carbon fixation, reduction, and regeneration.

The chemical equation for this process is: In plants, photosynthesis occurs mainly within the leaves.

Since photosynthesis requires carbon dioxide, water, and sunlight, all of these substances must be obtained by or transported to the leaves.If photosynthesis came to an abrupt end, most plants would die within short order.Although they could hold out for a few days -- or in some cases, a few weeks -- how long they lived would largely be a factor of how much sugar they had stored within their cells.In carbon fixation, carbon dioxide is combined with a 5-carbon sugar [ribulose1,5-biphosphate (Ru BP)] creating a 6-carbon sugar.In the reduction stage, ATP and NADPH produced in the light reaction stage are used to convert the 6-carbon sugar into two molecules of a 3-carbon carbohydrate, glyceraldehyde 3-phosphate.The chemical energy is stored in the form of glucose (sugar).Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water.The dark reactions do not require direct light, however dark reactions in most plants occur during the day.Light reactions occur mostly in the thylakoid stacks of the grana.The plant then uses them to make glucose/sugar, which is the energy/food for the plant.Oxygen is also produced by the plant in this cycle, which is then let off into the air!

    Have you ever noticed that plants need sunlight to live? It seems sort of strange doesn't it? How can sunlight be a type of food? Well, sunlight is energy and photosynthesis is the process plants use to take the energy from sunlight and use it to convert carbon dioxide and water into food. Three.…

    Photosynthesis - Part I The Sun and Light Not all of the light from the Sun makes it to the surface of the Earth. Even the light that does make it here is reflected and spread out. The little light that does make it here is enough for the plants of the world to survive and go through the process of photosynthesis. Light is actually energy.…
