How are cellular respiration in cells and combustion alike?

They are both redox reactions involving reacting oxygen with a fuel (glucose), generating energy in the process. If you are familiar with the chemical definition of a combustion reaction, it can be seen that the overall equation of cellular respiration is exactly the same as the chemical reaction for burning glucose in air. However, even though the overall equation is the same, the actual process of cellular respiration is much more controlled than regular combustion (otherwise we'd all be burning inside our cells).

What goes through photosynthesis?

During photosynthesis, plants and some other organisms convert carbon dioxide and water into glucose (sugar) and oxygen. This process requires sunlight to provide the energy needed to power the chemical reactions that transform these materials.

When photosynthesis take place the plant gives off?

When photosynthesis takes place, plants give off oxygen as a byproduct. Oxygen is released into the atmosphere through small pores in the plant's leaves called stomata. This process helps to replenish and maintain the oxygen levels in the atmosphere.

Where is the xylem in a carrot?

In a carrot, the xylem is located in the vascular bundle within the carrot's root. The xylem tissue is responsible for transporting water and nutrients from the carrot's roots to the rest of the plant.

Name the type of energy that is required for photosynthesis to occur?

An elementary-level answer would be : chemical and light energy

Light energy from the sun

Chemical from the plant itself.

light would be when the sun gives its light to help the plant grow like a light bulb, and chemical is like the plant taking the water, and soil and using it and the plant itself is chemical

Polythene can burn in oxygen to make carbon dioxide and water what is the formula?

polythene is a polymer of ethene. polythene primary while synthesis is a waxy solid, but it is made into transparent form by processing. The waxy solid which is the pure polythene burns in oxygen at elevated temperature to give carbon dioxide and water. but the processed polythene which we use in our daily lives, will burn in air to form CO2 and H2O along with other substances say carbon particles viz SPMs'. the equation is such that: -

(C2H4)n + 3nO2 ----> 2nO2 + 2nH2O

I am doing research on extraction of fuel from polythene, so I know a little on combustion products of polythene

What are the three main ingredints in photothinsesis?

the three main ingredients for photothensesis are light, oxygen and carbon dioxide.

C6H12O6 plus 6O2 - - - - - - - 6CO2 plus 6H20 plus engery what is this process called?

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

The reaction above is a combustion reaction. Specifically, this is glucose combustion, also known as cellular respiration.

How do you test that sunlight is necessary for photosynthesis?

You can test the necessity of sunlight for photosynthesis by conducting an experiment with plants placed in varying light conditions. One group should be exposed to sunlight, while another is kept in the dark. Measure factors like oxygen production or starch accumulation to determine the impact of sunlight on photosynthesis.

How does photosynthesis help the planet?

Photosynthesis helps the planet by converting carbon dioxide into oxygen, which is needed for most living organisms to survive. It also provides energy for plants to grow and serves as the base of the food chain, supporting the entire ecosystem. Overall, photosynthesis plays a crucial role in maintaining the balance of gases in the atmosphere and sustaining life on Earth.

How do cells get more ATP to replace what is used in cellular respiration or photosynthesis?

Cells can generate more ATP through processes like glycolysis, the citric acid cycle, and oxidative phosphorylation in cellular respiration, or through the light-dependent and light-independent reactions in photosynthesis. These processes involve the conversion of energy stored in molecules like glucose or sunlight into ATP through a series of chemical reactions.

Does chlorophyll have anything to do with water?

Yes, chlorophyll is responsible for capturing light energy during photosynthesis in plants, a process that requires water. Water is essential for the overall process of photosynthesis, as it is the source of electrons and protons used to convert carbon dioxide and light energy into glucose and oxygen.

Do ants living in modified leaves affect photosynthesis?

It depends on how the leaves are modified, but probably not. Most leaf modifications will decrease photosynthetic output due to increased storage capacity or defense against predators (needles). The ants probably wouldn't affect photosynthesis because the leaves aren't generally modified for greater photosynthesis anyway.

What plant organelle captures light energy from the sun to produce oxygen and sugar?

Chloroplasts are responsible for capturing light energy from the sun and using it to produce oxygen and sugar through the process of photosynthesis. This organelle is found in plant cells and is where the green pigment chlorophyll is located.

Explain The oxygen generated by photosynthesis is simply a by-product formed during the production of ATP and Carbohydrates?

You're not going to learn anything by looking up your text book questions online. You're not going to learn by having us spit the answers at you. YOU have to actually do the work if you want to get anywhere in life. That applies in every situation. So you might as well start now. Don't underestimate yourself. YOU CAN do it if you really try.

What is Carbon Dioxide and water and glucose?

Carbon dioxide is a colorless gas composed of one carbon atom and two oxygen atoms. Water is a clear, odorless, and tasteless liquid composed of two hydrogen atoms and one oxygen atom. Glucose is a simple sugar molecule consisting of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms.

During the photosynthesis light energy in chemical bonds What also happens according to the predictions of the second law of thermodynamics?

According to the second law of thermodynamics, some of the light energy absorbed during photosynthesis is lost as heat energy due to inefficiencies in the conversion process. This means that not all the light energy is converted into chemical energy in the bonds of glucose molecules produced during photosynthesis.

In the same garden two rose bushes were planted close together and one rose was planted on its own why did the rose bush on its own grow bushier and produce more flowers?

The rose bush planted on its own had more access to nutrients, sunlight, and water since it didn't have to compete with the other two bushes for resources. This allowed it to grow bushier and produce more flowers compared to the ones planted close together.

Is the Following true or false Photoheterotrophs can either consume organic material from other organisms or perform photosynthesis?

False. Photoheterotrophs are heterotrophic organisms that use light for energy but cannot use carbon dioxide as their sole carbon source. Examples would be purple non-sulfur bacteria, green non-sulfur bacteria, or heliobacteria.

What is the role of photosynthesis in food chain?

Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into energy-rich molecules like glucose. These organisms form the base of the food chain, as they are able to produce their own food. Other organisms in the food chain, such as herbivores, carnivores, and omnivores, rely on these energy-rich molecules produced through photosynthesis to survive.

Explain why farmers regularly add nitrate fertilizers to their field?

It's not entirely true to say, "...regularly add nitrate fertilizers..." since farmers in the US generally select the kind of fertilizers to use based on the nutrient needs of the crop, timing of application, and price of the fertilizer material. Nitrate fertilizers are one form they can use to get nitrogen, possibly the single most important nutrient, to their crops. However, nitrates are not always the most appropriate form to use, and so they also use ammonium types such as urea or anhydrous ammonia.

What Virginia system moves raw materials to factories and finished products to makets?

The transportation system in Virginia, consisting of highways (Interstate system), railways, and ports, serves to move raw materials to factories and finished products to markets efficiently. This system allows for the seamless movement of goods within the state and beyond, supporting the economy and facilitating trade.

What Experiments to look that photosynthesis need sun light?

To prove that light is needed for photosynthesis you must:

1. De-starch a plant by leaving it 48 hours in the dark.

2. Cover part of a leaf

3. Allow the plant to photosynthesis in light for 4 hours

4. Test leaf for starch (starch turns iodine solution black)

*Starch should not be present in the area you have covered as light is will not have been able to pass through.

*You can use black masking tape or aluminum foil to cover the wanted area of the leaf.

What type of cellular respiration forms the most ATP?

Aerobic cellular respiration forms the most ATP. It involves a series of metabolic reactions that occur in the presence of oxygen to fully break down glucose, producing a total of 36-38 ATP molecules per glucose molecule.

Once carbon has been converted to food by plants what three things can happen to it?

1. Plants respire and carbon dioxide is. released at night.

2. Plants are eaten by animals and animals respire and carbon dioxide is released.

3. Plants and animals die and are decomposed. Decomposers release carbon dioxide from decaying matter into the air.
