What is the energy source for photosynthesis?

What is the energy source for photosynthesis?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

Which of the following statements is false sunlight is the energy source for plant photosynthesis?

Option 1: Sunlight is the energy source for plant photosynthesis. True: In photosynthesis, plants convert light energy from the sun to chemical energy in the form of glucose. Option 2: Chlorophyll is contained in organelles called chloroplasts.

What is the role of chlorophyll in photosynthesis?

Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

What is the energy source for photosynthesis quizlet?

sunlight

Which is the most important factor in the process of photosynthesis?

Carbon Dioxide Concentration: In normal conditions, carbon dioxide is the major limiting factor in photosynthesis. The rate of photosynthesis increases with an increase in the C02 concentration.

What is the main product of photosynthesis quizlet?

The major product of photosynthesis is glucose, and it is made mainly of carbon.

What are the two main by products of photosynthesis?

Summary. The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas.

What are two major products of photosynthesis quizlet?

Photosynthesis uses carbon dioxide and water, produces glucose and oxygen, and takes place in chloroplasts.

What two products are made during photosynthesis?

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

What is the main product and by product of photosynthesis?

The three important elements required for photosynthesis process are Water, carbon dioxide and light. The product formed from this process, stored in the form of sugars, which are created from water and carbon dioxide. The by-product of the photosynthesis process is oxygen.

Which of the following is a direct product of photosynthesis?

The direct products of the light reactions and the Calvin cycle are 3-phosphoglycerate and G3P, two different forms of a 3-carbon sugar molecule. Two of these molecules combined equals one glucose molecule, the product seen in the photosynthesis equation

What organisms are capable of photosynthesis?

Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).

What are the end products formed in photosynthesis and respiration?

Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration (Figure 4).

What is created during photosynthesis?

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds

What three factors affect the rate of photosynthesis?

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

  • Light intensity. Without enough light, a plant cannot photosynthesise very quickly – even if there is plenty of water and carbon dioxide.
  • Carbon dioxide concentration.
  • Temperature.

What happens to ATP during photosynthesis?

During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.

Does photosynthesis produce oxygen?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
