 * What is Photosynthesis?**
 * The definition of photosynthesis is the process of where greens and other living creatures use sunlight to make foods from carbon- dioxide and water.**
 * __What is Photosynthesis?__**
 * Photosynthesis comes from the Greek words light and putting together. Photosynthesis occurs in plants, algae, and different types of bacteria. In photosynthesis plants use sunlight energy to put together carbon- dioxide from the air and water from the soil to make sugar! While photosynthesis is occurring oxygen is given off as a secondary product or by-product. Photosynthesis is w****hen sunlight is attracted to a plant or its leaves and the plant stores this to create energy. Living Organisms release carbon- dioxide into the air and the plants stomata’s take in this carbon dioxide and store it to again create energy and food. After this process is complete the plant releases oxygen into the air which is what humans and other living organisms need to breathe. The process of Photosynthesis starts is when the sunlight hits the chlorophyll of a plant’s leaves and then light and energy is stored as chemical energy and in the chloroplasts. Chloroplasts are little particles on a plant that suck in light and transform it into sugar and chlorophyll is the substance that makes a plant green.**


 * The Carbon- dioxide from living creatures goes into the plant and that is how the plant makes its food. When the plant takes in this Carbon- Dioxide it eventually releases oxygen which the human or any other living organism takes in through their respiratory system which allows the human to breathe. The Carbon- dioxide enters the plant through the small openings on the bottom of the leaf. These are called stomata’s. Stomata’s are the small opening on the bottom of the leaf that takes in the Carbon- Dioxide. Then after it takes in the carbon- dioxide it releases it as oxygen after it makes its food . As the plant makes food it releases oxygen as “waste”. Most plants make their own food using the energy that they get from the sun. To prove this if you take a leave and cut it in half and put in under a microscope and you will see little cells.**

**__Sugar__**
 * Sugar is made through Photosynthesis. Glucose to be specific is produced by Photosynthesis. Glucose is one of the main products of photosynthesis and fuels for cellular respiration. When Glucose and Oxygen combine they release energy. Glucose burns in a chemical process also known as cellular respiration. There are two stages of photosynthesis. The first type of photosynthesis is called the light reactions. The light reactions store light and energy in a chemical form (ATP). The second type of Photosynthesis is called dark reaction. The dark reactions use the stored energy to form sugars. Both light and dark reactions happen when the sun is out but only the dark reaction can happen both while the sun is out and when it is dark. Each year150 to 200 tons or (136 to 181 metric tons) of sugar are produced through photosynthesis.**



**__Glucose__**
 * Glucose. Glucose actually comes from the Greek word for fermenting or bacteria filled fruit juice or any type of sweet wine or just to be basic the sweetness of something. Glucose is basically just a certain type of sugar. Glucose is a sugar that Photosynthesis produces. Basically glucose is just sugar. Glucose is in lots of food. Glucose is found in fruits, pasta, and a few more foods. Glucose is a sugar carbohydrate. A sugar Carbohydrate is basically sugar that is either stuck together or spread out but contains a lot of glucose or sugar. The glucose in fruits is very good for you. As we already mentioned glucose is in fruits. Fruits are good for you but they contain lots of sugar and people don’t really realize it.**
 * __Life Cycle of a Plant__**


 * We need to know the life cycle on how plants come and go. Well let’s just say that a plant sprung up. Plants don’t just stay there forever. Usually animals eventually come and eat the plant. Living Organisms such as animals release carbon-dioxide into the air. Plants use this carbon-dioxide to make food and energy and later release oxygen.**


 * Glossary:**
 * Carbon- Dioxide- Carbon- Dioxide is the substance that humans and other living creatures breathe out. It is a natural type of gas.**
 * Chlorophyll- chlorophyll is the substance in plants that makes the plant and its leaves green.**
 * Chloroplasts- Are the tiny particles found in plant cells which enforce Photosynthesis.**
 * Glucose- Glucose is a simple form of sugar.**
 * Photosynthesis- Photosynthesis is when the sunlight hits the plant and then living organisms breathe out Carbon-Dioxide. Then the plants stomata takes in the Carbon-Dioxide and energy from the sunlight and makes food and releases oxygen as waste which humans and other living organisms breathe out.**
 * Stomata- Are the little holes on the backside of a leaf which takes in the Carbon- Dioxide which living organisms breathe out.**
