In a nutshell, photosynthesis is a process that enables plants to get energy from the sun. It may not sound too important when put like that, but when you start to think about where our food comes from, then it gets a lot more interesting. If you have eaten plants like fruit, vegetables, or cereal then the energy in that food was obtained from the sun — using photosynthesis!
The word photosynthesis can be separated to make two smaller words: Most plants are able to make their own food whenever they need it. This is done using light and the process is called photosynthesis.
Photosynthesis is the process by which plants make their own food. We will add more details to this definition after making a few things clear as you will see below. What is needed for Photosynthesis? To make food, plants need not just one but all of the following: Carbon dioxide from the air passes through small pores holes in the leaves.
These pores are called stomata. Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves. Sunlight is absorbed by a green chemical in the leaves. What happens during Photosynthesis?
The photosynthesis process takes place in the leaves of plants. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color.
It is this energy that is used to split water molecules into hydrogen and oxygen. Oxygen is released from the leaves into the atmosphere.
Hydrogen and carbon dioxide are used to form glucose or food for plants. Some of the glucose is used to provide energy for the growth and development of plants while the rest is stored in leaves, roots or fruits for later use by plants.
Here is the process in greater detail: Photosynthesis occurs in two stages commonly known as Light dependent Reactions and the Calvin Cycle.
Light dependent Reactions Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy.
Chlorophyll and other pigments absorb energy from sunlight. This energy is transferred to the photosystems responsible for photosynthesis. Water is used to provide electrons and hydrogen ions but also produces oxygen. Do you remember what happens to the oxygen?
ATP is an energy storage molecule. More details about the formation of sugars can be found under the Process of Photosynthesis in Plants. What have you learned so far?This is a photosynthesis chemical response that shows plants changing carbon dioxide and water into food.

Chlorophyll makes leaves green. It also traps the energy from the sun so the plant can use it.; When plants take carbon dioxide from the air, they release oxygen.
