What is the net gain of ATP in Photosynthesis?

The net gain of ATP in photosynthesis is 3 molecules of ATP per 1 molecule of glucose produced in the Calvin cycle. This ATP is generated through the light-dependent reactions that occur in the thylakoid membranes of chloroplasts.

What is the photosynthesis reaction equation?

6H20 + 6CO2 + Light Energy -----------> C6H12O6 + 602

Water + Carbon Dioxide + Light Energy --------> Glucose + Oxygen

Photosynthesis takes place in the plant cell's chloroplasts.

Photosynthesis uses sunlight to convert carbon dioxide and water into what?

Photosynthesis uses sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen. This process occurs in the chloroplasts of plant cells and is essential for the growth and survival of plants.

How does cacti obtain CO2 needed for photosynthesis?

Cacti obtain CO2 needed for photosynthesis through small pores called stomata on their stems. These stomata open at night when it is cooler to minimize water loss through evaporation. During this time, cacti take in CO2 and store it for use in photosynthesis during the day.

During photosynthesis plants produce sugar and what?

During photosynthesis, plants produce glucose (sugar) and oxygen as byproducts. The glucose is used as energy for the plant, while the oxygen is released into the atmosphere as a waste product.

Do all cells of a plant undergo photosynthesis?

No, not all cells in a plant undergo photosynthesis. Photosynthesis primarily occurs in specialized cells called chloroplasts, found mainly in the leaves of plants. Other cells in a plant, such as root cells or stem cells, do not typically undergo photosynthesis.

The nitrogen cycle involves photosynthesis and respiration?

The nitrogen cycle does not directly involve photosynthesis or respiration. It is a biogeochemical process that describes how nitrogen is converted and cycled through the environment by bacteria, plants, and other organisms. Nitrogen is fixed by bacteria, taken up by plants, and then returned to the soil through decomposition.

How do you put photosynthesis and chalet into a sentence?

Photosynthesis is the process in which plants convert sunlight into energy, while a chalet is a type of alpine house. The chalet's location high in the mountains allows for ample sunlight, which could support photosynthesis for any plants nearby.

Main product of plants?

To answer this question we need to understand the life cycle of a plant. The life cycle of a plant starts with a seed. This seed is then planted in the ground. This seed grows up to be a fully grown plant. The grown plant then produces more seeds. These seeds are then planted. For example, Look at the Dandelion. When someone picks it and blows on it, it's seeds go everywhere. Then the cycle begins again. So to answer your question, the end products of plants are more plants.

Which the chemicals are the ingredients used in photosynthesis?

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

Where do the supply of electrons come from in photosynthesis?

The supply of electrons in photosynthesis comes from water molecules. This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis. Water molecules are broken down into oxygen, protons, and electrons, with the electrons being used to replenish the electrons lost in the photosystem II reaction center.

What is the relationship between chlorophyll and chloroplasts?

Chlorophyll is a pigment found in chloroplasts that absorbs light energy during photosynthesis. Chloroplasts are the organelles in plant cells where photosynthesis occurs, and they contain chlorophyll in their thylakoid membranes. Chlorophyll captures light energy and converts it into chemical energy that can be used by the plant cell.

What are the processes of photosynthesis and transpiration?

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Transpiration is the process by which plants release water vapor through small openings called stomata on their leaves, helping to regulate temperature and transport nutrients throughout the plant. Both processes are vital for the survival and growth of plants.

What organelle needed for photosynthesis found in ground tissue?

Chloroplasts are the organelles needed for photosynthesis and are found in the ground tissue of plants. Through the process of photosynthesis, chloroplasts capture sunlight and convert it into energy for the plant to use.

Does photosynthesis or cellular respiration only occur in plants?

No, both photosynthesis and cellular respiration occur in plants as well as in other organisms such as bacteria, fungi, and animals. Photosynthesis is the process by which plants use sunlight to produce energy, while cellular respiration is the process by which organisms use oxygen to break down glucose and produce ATP for energy.

Do plants give oxygen off when using photosynthesis?

Yes, during photosynthesis, plants take in carbon dioxide and water and use sunlight to produce glucose and oxygen as byproducts. Therefore, plants release oxygen into the atmosphere as a result of the photosynthetic process.

The dark reactions of photosynthesis are those that?

The dark reactions of photosynthesis, also known as the Calvin cycle, occur in the stroma of the chloroplast and do not require light energy. They involve the conversion of carbon dioxide into glucose through a series of enzymatic reactions. The dark reactions use the products of the light reactions, ATP and NADPH, as sources of energy and reducing power.

What is the main difference between the end result of photosynthesis and the end result of cell respiration?

The end result of photosynthesis is the ingrediants neccesary for cellular respiration, and vice versa. In other words:

Photosynthesis

6H2O + 6CO2 = C6H12O6 + 6O2

Cellular Respiration

C6H12O6 + 6O2 = 6H2O + 6CO2

What parts of a plant remains on the plant even after several years of growth?

The roots, stem, and older woody branches of a plant typically remain on the plant even after several years of growth. These structures provide support, transport nutrients, and anchor the plant in the ground.

What are most of the PGAL made in the Calvin cycle are used for?

Most of the PGAL produced in the Calvin cycle is used to regenerate RuBP (ribulose-1,5-bisphosphate) to continue the cycle. Some PGAL molecules are also used to synthesize glucose, which can be further converted into starch or other carbohydrates for energy storage.

What is the liquid needed for photosynthesis?

one hundred percent

improvment: Well... 100%

minus the water for the metabolism, the anabolism, the katabolism and the transpiration But this factors are differend with each plant and each location. So there are no absolut numbers. added by Neramo

CO2 H2O light energy sugar O2?

Carbon dioxide (CO2) is used by plants during photosynthesis along with water (H2O) and light energy to produce sugar and oxygen (O2) as a byproduct. This process is essential for the growth and survival of plants.

Differentiate light dependent reaction from light independent reaction of photosynthesis in terms of row materials?

The light-dependent reaction of photosynthesis requires light energy, water, and ADP + Pi to produce oxygen, ATP, and NADPH. The light-independent reaction, or the Calvin Cycle, does not directly require light but uses the products of the light-dependent reaction (ATP and NADPH) along with carbon dioxide to produce glucose.

What animals use photosynthesis?

No animal photosynthesizes it is only plants that can do this. However some animals (like corals) have a symbiosis with a plant that enables them to use plant energy without eating the plant.
