What do fossil fuels contain from the Sun's radiant energy via photosynthesis?

Fossil fuels contain stored energy from the Sun's radiant energy that was captured by plants through photosynthesis millions of years ago. This energy is stored in the form of carbon compounds such as coal, oil, and natural gas. When burned, these fuels release the stored energy in the form of heat, which we use for various purposes.

How does photosynthesis happens?

Photosynthesis Happens when carbon dioxide enters the green parts of the leaf where the chloroplast is, which has chlorophyll in. When the carbon dioxide reaches it it shoots out oxygen and sugars (Food). Photosynthesis occurs when carbon dioxide (CO2) enters the stomata on the under side of leaves. Chlorophyll is the responsible for the coloration of the leaves. The products are oxygen and sugars. The reactants are carbon dioxide and water. *Stomata are microscopic holes on the underside of leaves.

How do plants obtain the raw materials they need for photosynthesis?

The raw materials for plants are Carbon dioxide, water, light and small amounts of chemicals like nitrogen, phosphorous and potassium.

Plants take in carbon dioxide through their tiny openings, the stomata, from the surrounding air .

They take water from the soil through their roots. The other chemicals are dissolved in the water and also absorbed through the roots.

What was the importance of photosynthesis in the evolution of the earths atmosphere?

Photosynthesis played a crucial role in the evolution of Earth's atmosphere by producing oxygen as a byproduct. This process greatly increased the amount of oxygen in the atmosphere, making it possible for aerobic organisms to thrive and leading to the development of more complex life forms. The rise of photosynthetic organisms also contributed to the stabilization of Earth's climate over time.

If Respiration exceeds Photosynthesis will plant grow or not?

I'm not sure if I am answering your question, but in autotrophic organisms - namely,

plants - photosynthesis occurs, using the energy from the sun to break water molecules,

combine the hydrogen ions with carbon dioxide from the environment, and leave some energy

left over in order to start the reactions of cellular respiration, which, in most plants, involves

breaking down the glucose entirely in order to collect the energy released in the form of an ATP

bond. Hope that answers your question.

What types of organisms perform photosynthesis?

Plants, algae, and some bacteria are organisms that perform photosynthesis. These organisms contain chlorophyll, a pigment that captures light energy and converts it into chemical energy through the process of photosynthesis.

What organisms can carry on photosynthesis?

Plants, algae, and some bacteria are organisms that can carry out photosynthesis. These organisms contain chlorophyll, a pigment that enables them to capture light energy and convert it into chemical energy in the form of glucose.

Can photosynthesis takes place in presence of light bulb?

No, photosynthesis cannot occur in the presence of a light bulb because the light emitted by the bulb does not contain the full spectrum of light wavelengths needed for the process. Plants require specific wavelengths of light, such as blue and red light, that are typically found in natural sunlight for photosynthesis to take place.

Why do plants only photosynthesis during the day?

Plants perform photosynthesis during the day because they require sunlight to produce energy for the process. Light is essential for plants to activate the chlorophyll in their cells, which helps convert carbon dioxide and water into glucose and oxygen. At night, in the absence of light, plants rely on stored energy reserves to sustain essential processes.

What three things do plants need for photosynthesis to occur?

Plants need light energy, carbon dioxide, and water to undergo photosynthesis. Light energy is absorbed by chlorophyll in the presence of carbon dioxide and water, leading to the production of glucose and oxygen.

What role does NADP play in photosynthesis?

NADP acts as a coenzyme in photosynthesis, accepting and carrying high-energy electrons to the Calvin cycle where they participate in the conversion of carbon dioxide into glucose. NADP is present in its reduced form (NADPH) after accepting electrons and can be used as a reducing agent in the synthesis of carbohydrates during photosynthesis.

Where does photosynthesis take place in a photoautotrophic bacterium?

Photosynthesis in photoautotrophic bacteria takes place in specialized cellular structures called chlorosomes. These structures contain pigments that capture light energy and convert it into chemical energy for the cell to use in synthesizing organic compounds.

What compounds are made by plants from glucose manufactured in photosynthesis?

Plants can use glucose to create a variety of compounds including starch for energy storage, cellulose for structural support, and various organic molecules like amino acids, lipids, and nucleic acids required for growth and development. Additionally, plants may also convert glucose into secondary metabolites such as alkaloids, terpenoids, and phenolic compounds that play roles in defense, signaling, and attraction.

Does the Eucalyptus tree get enough light for photosynthesis?

Eucalyptus trees typically grow in sunny environments and require significant light for photosynthesis to occur efficiently. They are adapted to thrive in areas with full sunlight, which is essential for their growth and development. In shaded or low-light conditions, eucalyptus trees may struggle to photosynthesize effectively.

What is the chemical formula for artificial light?

The chemical formula for artificial light is typically not represented by a single formula, as it encompasses a wide range of technologies and sources such as incandescent bulbs (tungsten filaments), fluorescent lights (mercury vapor and phosphor coatings), and LED lights (semiconductor materials). Each type of artificial light source has its own specific chemical components and mechanisms.

Grana thylakoids and stroma are all components found in?

Grana, thylakoids, and stroma are components found in chloroplasts, which are organelles responsible for photosynthesis in plant cells. Grana are stacks of thylakoids where light reactions occur, while stroma is the fluid-filled space where the Calvin cycle (dark reactions) takes place. These components work together to convert light energy into chemical energy in the form of sugars.

Why is water essential for plant growth?

water is essential for the following reasons:

Solvent

Water acts as the solvent for the minerals present in the soil and with the absorption of water from the soil minerals also enters the plant body. While these minerals could not be easily and naturally taken up by the plants if they were in solid state.

Transport

Water is used to transport the metabolic products from one part to the other where they are needed. So it acts as a vehicle for the transportation.

Photosynthesis

Photosynthesis is a process in plants to make their food. And water is an electron source of this process.

6CO2 + 6H2O â€" C6H1206 + 6O2

In this process six water molecules combine with six carbon molecules to form, oxygen and glucose (food for plants)

Evaporation

Water is evaporated through the stomata present on the leaves. It cools the plant in the hot sunny days, in the similar manner as we get cool by perspiration. Roots also store the water to be used in winter. In cold days water movement from the soil is very slow but the leaves loses water by wind in the winter too. So the stored water helps the plant to compensate with it. If no water is available to the plant then the tissues will start dying in the leaves and they will turn brown in color. Evaporation is also necessary for plant to let the stomata remain open for the intake of carbon dioxide.

Turgidity

Water is necessary for the turgidity i.e. the pressure of water in the cells of plants which is important for the survival of plant else it will wilt. It is also required for the growth as it expands the plant cells.

Light depends on reactions of photosynthesis produce ATP and nadph but they are not in the overall final reaction that is written out for photosysnthesis why?

While the products of the light reactions, ATP and NADPH, are not explicitly shown in the overall chemical equation for photosynthesis, they are crucial for the dark reactions (Calvin cycle) where they provide the energy and reducing power needed to convert carbon dioxide into glucose. The overall equation for photosynthesis simplifies the process and highlights the conversion of carbon dioxide and water into glucose and oxygen.

What pigment is responsible for photosynthesis?

Chorophyll a is essential.It is needed to direct photosynthesis.

Besides food what other materials are useful to humans that are products of photosynthesis?

Some materials useful to humans that are products of photosynthesis include wood for construction and paper, biofuels such as ethanol and biodiesel for energy, and natural fibers like cotton and hemp for clothing. Oxygen released during photosynthesis is also essential for human respiration.

The end products of photosynthesis are?

Photosynthesis is the process by which a plant makes its own food. The end result of photosynthesis is the production of glucose to feed the plant, and the production of oxygen, for humans to breathe.
