What is the science definition for photosynthesis?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose or other organic compounds. This process involves the conversion of carbon dioxide and water into sugars using the energy absorbed from sunlight by chlorophyll. Oxygen is produced as a byproduct of this reaction.

What is the balance equation of the photosynthesis?

The equation for balanced photosynthesis is:

6CO2 + 6H2O ------> C6H12O6 + 6O2

What are the raw materials needed to make sunglasses?

The raw materials needed to make sunglasses include plastic or metal frames, lenses made of plastic, glass, or polycarbonate, nose pads, screws, hinges, and temple tips. Optional materials can include coatings for UV protection or tinting for the lenses.

What is the formula for photosynthesis formula for Photosynthesis 7.4.2011?

The overall formula for photosynthesis is: 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. This equation represents the process by which plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight as a source of energy.

How does African forest elephant use photosynthesis and cellular respiration?

African forest elephants, like all animals, do not perform photosynthesis. They obtain energy by consuming plants or plant-based materials. Through the process of cellular respiration, the elephants break down the organic matter from their food to produce energy for their bodily functions.

Which part of the chloroplast does the calvin cycle occur in?

The Calvin cycle, which is the process of carbon fixation in photosynthesis, occurs in the stroma of the chloroplast. This is where the enzymes and molecules involved in the cycle are located, allowing for the conversion of carbon dioxide into glucose.

Did thomas engelmann use bryophytes in his studies of how plants use light for photosynthesis?

Yes, Thomas Engelmann utilized bryophytes in his studies to investigate how plants utilize light for photosynthesis. Engelmann is best known for his pioneering work on the action spectrum of photosynthesis, where he used Spirogyra algae to demonstrate the relationship between light wavelengths and photosynthetic activity.

Suppose there were singled-celed protozoans in the test tube with Elodea when you the white light experiment. Could you still calculate Elodea's rate of photosynthesis?

Yes, you could still calculate Elodea's rate of photosynthesis by measuring the change in dissolved oxygen in the water over time. The presence of single-celled protozoans would not significantly affect the ability to measure the rate of oxygen production by the Elodea.

What does the cycle photosynthesis mean?

The process by which plants and other organisms convert carbon dioxide and water into glucose (energy) using sunlight is called photosynthesis. This process also produces oxygen as a byproduct, which is essential for supporting life on Earth.

What is the green substance in plants that need photosynthesis?

Within plant cells, there are organelles called chloroplasts which contain chlorophyll. These organelles allow the cell to undergo photosynthesis by converting water, sunlight and carbon dioxide into glucose and oxygen. The reason why they are green is to allow the most sunlight to be absorbed (absorb all other coloured wavelengths especially the blues and reds).

What product of photosynthesis is used in cellur respiration?

The product of photosynthesis used in cellular respiration is glucose. Glucose is created during photosynthesis and then broken down in cellular respiration to produce energy for the cell.

Does a water lily use photosynthesis?

Of course it does. It is a green photosynthetic organism just like other vascular plants. It uses blue and red light (not green light) to make glucose (sugar) from CO2 and water. The source of the water for a water lily is simple enough to understand however where it gets its CO2 is more problematic. Water lilies do have stomates in the upper surfaces of their leaves so they can take up CO2 directly from the atmosphere. They also have an internal gas plumbing system called aerenchyma and so they can absorb CO2 dissolved in the water (just like algae) and they can also use CO2 from the mud in the bottom of the pond. If you cut a petiole of a water lily leaf underwater gas with a lot of CO2 in it will bubble out for hours. Analysis shows that it usually has a lot more CO2 in it than is found in air.

*I am currently publishing a paper in the International Journal of Plant Sciences on Photosynthesis in water lilies. Dr Raymond J Ritchie

What molecules are needed for photosynthesis?

Since the chemical equation for photosynthesis is :

6 CO2 + 6 H2O + light energy --> C6H12O6 + 6 O2

This means that carbon dioxide, light energy, and water molecules are needed for photosynthesis ( to produce glucose and oxygen).

How do you properly perform ghusl?

To perform ghusl (ritual bath), you should intend to cleanse yourself from major impurity, then wash your private parts. Next, perform a complete ablution (wudu) as you would for prayer, and finally pour water over your entire body three times. Make sure water reaches every part of your body. This is typically done when you have had sexual intercourse, after menstruation or postpartum bleeding, or after the emission of semen.

What transported raw materials to factories and produed to cuctomers and supervising large numbers of workers?

Railroads and trucks were commonly used to transport raw materials to factories and finished products to customers. Managers and supervisors oversaw large numbers of workers in the factories to ensure smooth production and quality control.

What are the end products of light-dependent reaction of photosynthesis?

Oxygen, Water, ATP, and NADPH are products of the light reactions in photosynthesis. The Calvin Cycle is what produces the products: Carbon dioxide, Sugar, NADP+, and ATP + phosphate. Dont let that trick ya!

Are Red orange and yellow pigments only present in a plant when photosynthesis stops?

No, red, orange, and yellow pigments can be present in plants even during photosynthesis. These pigments, such as carotenoids and anthocyanins, play important roles in capturing light energy and protecting the plant from damage caused by excess light. Additionally, they contribute to plant coloration, serving functions beyond photosynthesis.

What are the products and reactants of photosynthesis Write the formula?

The reactants of Photosynthesis are water and carbon dioxide which are acted upon by light and enzymes to produce oxygen and glucose.

6H2O + 6CO2 ----light energy and enzymes--> 6O2 + C6H12O6

water + carbon dioxide oxygen + glucose

What cellular organelle are responsible for photosynthesis in green plants?

Chloroplasts are the cellular organelles responsible for photosynthesis in green plants. They contain chlorophyll, which captures sunlight and converts it into energy through a series of biochemical reactions. This process ultimately produces glucose for the plant to use as energy.

What are the low reactants in photosynthesis?

fier light and electricity may be considered low reactants in plants

Which organelle in plants and animals is involved in carrying out the reaction in this equation in the forward direction?

Chloroplasts in plants and mitochondria in animals are the organelles involved in carrying out the reaction in both the forward and reverse directions. Chloroplasts perform photosynthesis, converting light energy into chemical energy, while mitochondria carry out cellular respiration, converting chemical energy into ATP.

Why does carbon dioxide leave the cell during cellular respiration?

Carbon dioxide is a byproduct of cellular respiration, where glucose is broken down to produce energy in the form of ATP. It diffuses out of the cell into the bloodstream and is ultimately expelled from the body through exhalation. This process helps to maintain the balance of gases in the body and prevent toxicity from high carbon dioxide levels.

What substances are directly involved in photosyntehsis?

The main substances directly involved in photosynthesis are carbon dioxide (CO2), water (H2O), and sunlight. These substances are utilized by plants to produce glucose and oxygen through the process of photosynthesis.

Which process involves ribulose bisphosphate?

Ribulose bisphosphate is involved in the Calvin cycle, a process that occurs in the chloroplasts of plants where carbon dioxide is fixed to produce sugars. This molecule plays a key role in capturing and incorporating carbon into organic compounds during photosynthesis.
