Photosynthesis

Plants make their own food through photosynthesis, a process that uses sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The green pigment chlorophyll in plant cells absorbs sunlight to facilitate this process, allowing plants to convert light energy into chemical energy they can use for growth and survival.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, occur in the stroma of the chloroplasts in plant cells. This process uses the products of the light-dependent reactions to convert carbon dioxide into sugars.

Yes, photosynthesis takes place in the chloroplasts of plant cells. Chloroplasts contain chlorophyll, the pigment that captures sunlight and converts it into energy through the process of photosynthesis. This process involves the conversion of carbon dioxide and water into glucose and oxygen using sunlight as the energy source.

No. It is not really a change at all. When you turn on a light you simply allow electrons to flow through a circuit and through a tungsten filament. The tungsten has high resistance and so electrons loose energy through collisions and release light at many various wavelegths. No materials are undergoing any changes. They end upp the same way as they started.

Yes, a cell can still undergo respiration when glucose is not available. In the absence of glucose, cells can use other molecules such as fats and proteins as alternative energy sources to carry out respiration. This allows cells to continue producing ATP for their energy needs.

Jan Ingenhousz hypothesized that plants produce oxygen during photosynthesis. He also proposed that the green parts of plants play a crucial role in this process.

The acceptor of electrons lost from chlorophyll in chloroplasts is the protein complex called plastoquinone. It is an essential component of the electron transport chain in the thylakoid membrane, where it transfers electrons to other components in the chain to generate ATP and NADPH during photosynthesis.

Cells use oxygen as the main gas in cellular respiration. Oxygen is used for the process of oxidative phosphorylation to produce ATP, the cell's main source of energy. Additionally, cells also produce carbon dioxide as a byproduct of cellular respiration.

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).

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 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.

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.

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 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

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

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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.
