The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process. It’s not particularly efficient by human engineering standards, but it does the job.
What is the most important thing needed for photosynthesis?
Terms in this set (17)
- where photosynthesis takes place leaves
- the process in which a plant makes food photosynthesis
- what is released from a plant after photosynthesis occurs oxygen
- a simple sugar glucose
- what humans breathe out and the gas plants need for photosynthesis carbon dioxide
- the green pigment in plants that captures sunlight chlorophyll
What are the most important steps of photosynthesis?
- CO2and H2O enter the leaf
- Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2
- The electrons move down to enzymes
- Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

What are the disadvantages of too much photosynthesis?
What are the disadvantages of too much photosynthesis? Even though light is the ultimate substrate for photosynthetic energy conversion, it can also harm plants. This toxicity is targeted to the water-splitting photosystem II and leads to damage and degradation of the reaction centre D1-polypeptide.
What is the main purpose of photosynthesis?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
What is the objective of chloroplast?
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth. They are classified as the producers of the world.
What does photosynthesis produce?
Photosynthesis is the process of creating sugar and oxygen from carbon dioxide, water and sunlight. It happens through a long series of chemical reactions. But it can be summarized like this: Carbon dioxide, water and light go in. Glucose, water and oxygen come out.
What is the formula for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is the process of photosynthesis?
Most life on Earth depends on photosynthesis .The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2) and chemical energy stored in glucose (a sugar).
What is the chemical used in photosynthesis?
ATP. Noun. (adenosine triphosphate) chemical found in most living cells and used for energy. C3 photosynthesis. Noun. Used by the majority of plants, it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become a sugar called glucose. C4 photosynthesis.
How does carbon dioxide change water into glucose?
Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
What is the energy that plants use?
Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.
Why are the leaves of plants green?
The plant leaves are green because that color is the part of sunlight reflected by a pigment in the leaves called chlorophyll. Photograph courtesy of Shutterstock. ATP.
What is the chemical element that forms the basis of all known life?
series of reactions that take place during photosynthesis, where carbon dioxide and water from the atmosphere are converted into sugar. carbon. Noun. chemical element with the symbol C, which forms the basis of all known life.
What part of the chloroplast is credited with media?
Part of the chloroplast where light-dependent reactions take place. Credits. Media Credits. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit.
What is the Function of Photosynthesis?
Some living things, including plants, algae, and certain bacteria, can make their own food, hence they are autotrophs. The primary way in which these living things make their food is through photosynthesis. Photosynthesis is quite common in green plants and other organisms such as algae.
Process of Photosynthesis in Plants
The process of photosynthesis in plants takes place in the chloroplast. A chloroplast is an organelle found in the cells of green plants, mainly in the leaves. Inside the chloroplast is a green pigment known as chlorophyll, which captures the light from the sun. The trapped light is then used in the synthesis of the plant's carbohydrates.
Introduction
As with the rest of my curriculum, I’ve gone through the College Board’s Course and Exam Description for AP Biology and extracted the following Learning Objectives, Enduring Understandings, and pieces of Essential Knowledge.
Photosynthesis related learning objectives
