Is Peanut a Cash Crop Or Food Crop?

Peanut is both a cash crop and a food crop. It is grown primarily for its commercial value as a cash crop, but it is also an important source of food products such as peanut butter, oils, and snacks for human consumption.

The first process in the light dependent reactions of photosynthesis?

The first process in the light-dependent reactions of photosynthesis is photon absorption by chlorophyll molecules in the thylakoid membrane of the chloroplast. Absorbed photons then excite electrons in chlorophyll, initiating the transfer of these high-energy electrons through a series of protein complexes known as the electron transport chain.

What is botanical name of apple?

Malus pumila Miller(old Name=pyrus malus), Family:Rosaceae

Which office plant provides the most oxygen?

The snake plant is known for its ability to produce oxygen at night, making it a good choice for improving indoor air quality. Another plant that is highly effective at producing oxygen is the pothos plant.

What are the necessary elements for photosynthesis to occur?

The necessary elements for photosynthesis to occur are sunlight, carbon dioxide, and water. These elements are used by plants to produce glucose (food) and oxygen. Chlorophyll, a pigment found in chloroplasts, is also essential for capturing the sunlight needed for the process.

What are the raw materials for photosenthesis?

The raw materials for photosynthesis are carbon dioxide, water, and sunlight. Carbon dioxide is absorbed from the air, water is taken up from the soil through the roots, and sunlight provides the energy needed to drive the photosynthetic process.

Why doesn't rubisco end in 'ase'?

Rubisco, or ribulose-1,5-bisphosphate carboxylase/oxygenase, is an enzyme involved in carbon fixation during photosynthesis. While many enzymes end in '-ase' to indicate that they are enzymes, rubisco derives its name from its function, which involves carboxylation and oxygenation reactions, rather than its enzymatic activity.

How does man benefit from photosynthesis in plants?

humans benefit from photosynthesis, by receiving, obviously oxygen, which is required for cellular respiration, but plants also provide, glucose, which we heterotrophs need, to perform cellular respiration again, so we benefit by receiving oxygen and glucose, or O2 and C6H12O6.

Is carbon dioxide a reactant in cellular respiration?

Yes, carbon dioxide is produced as a byproduct of cellular respiration in the mitochondria of cells. It is not a reactant in the initial steps of cellular respiration, but is produced during the Krebs cycle and then released as waste.

What do chlorophyll molecules do?

they essentially absorb all spectrum of light to give energy to the plant and reflects the green light. therefore they are responsible for the green colour of the plant as it contains pigments.

How are cellular respiration and photosnythesis almost opposite processes?

Cellular respiration process = CO2 + H2O + Sunlight = O + C6 H12 06

Photosynthesis = O + C6 H12 06 = CO2 + H2O + Sunlight

The formula is switched

How does photosynthesis moderate the greenhouse effect?

As far as CO2 is involved, Photosynthesis is by far and away the Best method of carbon capture and STORAGE [within Earth's Soil] that We Possess; and this [as well as any, every and all forms of ] Removal of CO2 from Our paper thin Atmosphere is what We Desire Most.

In which organism does photosynthesis take place?

Photosynthesis takes place in plants, algae, and some bacteria. These organisms contain chlorophyll, a green pigment that captures sunlight and converts it into chemical energy to fuel the process of photosynthesis.

Which reactions require oxygen as a raw material 1 light reactions only 2 dark reactions only 3 both light and dark reactions 4 niether light or dark reactions?

  1. The light reactions of photosynthesis require oxygen as a raw material to produce ATP and NADPH.
  2. The dark reactions (Calvin cycle) of photosynthesis do not directly require oxygen as a raw material, but they use the ATP and NADPH produced in the light reactions.
  3. Both light and dark reactions are involved in photosynthesis, but only the light reactions require oxygen as a raw material.

What raw materials do green plants use in the process of photosynthesis?

Some raw materials for photsynthesis can be collected from their respective enviorments. The basic materials are water(H2O) and carbon dioxide (CO2). the products that the plants realse are oxygen(o2) glucose (C6H12O6) and water(H20). However, the same materials in are not ressacarily the same matierals out. The water that is brought into the system in the beginning breaks down into oxygen. Also, only some products are actually released in to the enviorment. The oxygen is one of them, plants take in carbon dioxide, what we breathe out and give us oxygen, what we run on. The Glucose is changed further down the road in to necasary materials for the plant to run on. As for the water, some water stays while others are used again. this is why the water is able to be found in many cacti

Supply chain for zara from raw materials?

Zara's supply chain starts with the sourcing of raw materials such as fabric and buttons from suppliers around the world. These materials are then sent to Zara's manufacturing facilities where they are transformed into finished products. The finished products are then distributed to Zara's stores globally or directly to customers through online sales channels. Zara focuses on fast production and delivery, allowing them to quickly respond to customer demand and trends.

What are the necessary conditions for photosynthesis to take place?

As we all rather know, photosynthesis is a process that takes place in the presence of sunlight-which is the primary source of energy for plants- apart from sunlight, other factors can be grouped into internal and external. The external features are; temperature, sunlight, water, carbon(ii)oxide and mineral salts. While the internal factors are; chlorophyll(the green pigment on the leaf of a plant) and enzymes.

Photosynthesis consists of two types of reactions?

There is a light reaction and a dark reaction (the Calvin Cycle). The light reaction is divided into 3 parts, Photosystem II, the Electron Transport Chain, and Photosystem I. The light reaction begins in Photosystem II when light hits the thylakoid so the chlorophyll loses and electron, and the electron moves up in energy levels and reaches the primary anceptor. From here it passes through the electron transport chain which is similar to the electron transport chain in cellular respiration, but it occurs in the thykaloids proton gradient is reversed through the membrane. Then it enters phtosystem I which is essentially the same thing as photosystem I, and the electrons from there pass through another electron transport chain. This produces ATP and NADPH which are used in the dark reaction, or Calvin Cycle, which is again similar to the Citric Acid Cycle but it begins with Acetyl acetate and produces 2 ATP 6 NADH and 1 FADH 2 per every 2 turns which are required to produce one glucose molecule, the ultimate goal of photosynthesis.

I hope this was enough detail.

What does carbon dioxide attach to in photosynthesis?

In photosynthesis, carbon dioxide attaches to a five-carbon sugar called ribulose-1,5-bisphosphate (RuBP) in a process called carbon fixation. This reaction is catalyzed by the enzyme RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase).

What is produced by reactions that take place in the thylakoids and are consumed by reactions in the stroma?

ATP and NADPH are produced by reactions in the thylakoids and are consumed by reactions in the stroma. The reason is because the reaction that takes place in the thylakoid is the light reaction and the one that takes place in the stroma is the light-independent reaction.

During the dark reactions the reaction center splits water?

During the dark reactions (Calvin cycle) of photosynthesis, water is not split. Instead, the dark reactions use the products of the light reactions (ATP and NADPH) to convert carbon dioxide into glucose through a series of enzyme-controlled reactions. The splitting of water occurs in the light reactions at Photosystem II to generate oxygen, electrons, and protons.

How much oxygen does the ocean give us?

The ocean produces about 50-85% of the Earth's oxygen through phytoplankton and seaweed. While the Amazon rainforest is often praised for its oxygen production, it actually contributes a smaller amount compared to the ocean.

Is a plant using CO2 and H2O to form O2 and sugar a chemical or a physical change?

It is a chemical change because you get two different chemical products.
