A Step-by-step Guide to Understand the Process of Photosynthesis
Oct 24, · Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Photosynthesis helps plants to generate glucose, carbohydrates, and oxygen by using carbon dioxide, water, and sunlight. In this article, we attempt to answer all your queries about this process. The foremost thing that one needs to understand is that photosynthesis is important for all lifeforms on the Earth and not just plants.
There is no questioning the fact that it occurs in plants, algae, and some species of bacteria, but indirectly, it helps all the organisms which cannot produce their own food, including humans.
Would you like to write for us? Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk Plants, algae, and species of bacteria that can produce their own food are known as photoautotrophs.
The process is also known as carbon fixation process, as it produces carbon compounds which store chemical energy meant to be used in cell growth. By definition, photosynthesis is a process by which photoautotrophs convert the energy derived from the Sun into usable chemical energy. Light, water, chlorophyll, and carbon dioxide are the basic requirements for this process. Carbon dioxide in the atmosphere enters the plant leaf through stomata, i.
Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water and transport it to the leaves through the stem. As sunlight falls on the leaf surface, the chlorophyll, i. Interestingly, the green color what is process of photosynthesis the leaf is also attributed to presence of chlorophyll. Then hydrogen and oxygen are produced by converting water using the energy derived from the Sun.
Hydrogen is combined with carbon dioxide in order to make waht for the plant, while oxygen what kind of peanuts to use for peanut brittle released through the stomata. Similarly, even algae and bacteria use carbon dioxide and hydrogen what is process of photosynthesis prepare food, while oxygen is let out as a waste product.
The electrons from the chlorophyll molecules and protons from the water molecules facilitate chemical reactions in the cell. These reactions produce ATP adenosine triphosphatewhich provides energy for cellular reactions, and NADP nicotinamide adenine dinucleotide diphosphateessential in plant metabolism. Photoshnthesis we take in oxygen and give out carbon dioxide to produce energy, plants take in carbon dioxide and give out oxygen to produce energy. Photosynthesis what does it mean to be held accountable several benefits, not just for the photoautotrophs, but also for humans and animals.
The chemical energy stored in plants oof transferred to animals and humans when they consume plant matter. It also helps in maintaining a normal level of oxygen and carbon dioxide in the atmosphere. Almost all the oxygen present in the atmosphere can be attributed to this process, which also means that respiration and photosynthesis go together.

What is Photosynthesis
The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later. Imagine a pea plant. If that pea plant is forming new pods, it requires a large amount of sugar energy to grow larger. Jan 11, · Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide. 2,24, Step by Step Process of Photosynthesis Step 1. The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that Step 2. Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. .
When you get hungry, you grab a snack from your fridge or pantry. But what can plants do when they get hungry? You are probably aware that plants need sunlight, water, and a home like soil to grow, but where do they get their food? They make it themselves! Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive.
This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water H2O through the roots, carbon dioxide CO2 from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose sugars and oxygen O2.
Just like you, plants need to take in gases in order to live. Animals take in gases through a process called respiration.
During the respiration process, animals inhale all of the gases in the atmosphere, but the only gas that is retained and not immediately exhaled is oxygen. Plants, however, take in and use carbon dioxide gas for photosynthesis. Plants also require water to make their food. For example, desert plants, like a cactus, have less available water than a lilypad in a pond, but every photosynthetic organism has some sort of adaptation, or special structure, designed to collect water.
For most plants, roots are responsible for absorbing water. The last requirement for photosynthesis is an important one because it provides the energy to make sugar.
How does a plant take carbon dioxide and water molecules and make a food molecule? The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar glucose and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair. The oxygen that is produced is released from the same tiny holes through which the carbon dioxide entered.
Even the oxygen that is released serves another purpose. Other organisms, such as animals, use oxygen to aid in their survival. The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later.
Imagine a pea plant. If that pea plant is forming new pods, it requires a large amount of sugar energy to grow larger. This is similar to how you eat food to grow taller and stronger. But rather than going to the store and buying groceries, the pea plant will use sunlight to obtain the energy to build sugar.
When the pea pods are fully grown, the plant may no longer need as much sugar and will store it in its cells. A hungry rabbit comes along and decides to eat some of the plant, which provides the energy that allows the rabbit to hop back to its home. Consider the process of photosynthesis. With the help of carbon dioxide and water, the pea pod used the energy from sunlight to construct the sugar molecules. When the rabbit ate the pea pod, it indirectly received energy from sunlight, which was stored in the sugar molecules in the plant.
We can thank photosynthesis for bread! Wheat grains, like the ones pictured, are grown in huge fields. When they are harvested, they are ground into a powder that we might recognize as flour. Humans, other animals, fungi, and some microorganisms cannot make food in their own bodies like autotrophs, but they still rely on photosynthesis.
Through the transfer of energy from the Sun to plants, plants build sugars that humans consume to drive our daily activities. Even when we eat things like chicken or fish, we are transferring energy from the Sun into our bodies because, at some point, one organism consumed a photosynthetic organism e.
