What are the 2 stages of photosynthesis Class 10?

What are the 2 stages of photosynthesis Class 10?

Photosynthesis takes place in two stages, namely light-dependent reactions and light-independent reactions. Light-dependent reactions are also called light reactions and occur during the day time. Light-independent reaction is also called the dark reaction or the Calvin cycle.

What are the stages in photosynthesis?

Photosynthesis takes place in two sequential stages: The light-dependent reactions; The light-independent reactions, or Calvin Cycle.

What are the two stages of photosynthesis and where does each occur?

Most autotrophs make food using photosynthesis. This process occurs in two stages: the light reactions and the Calvin cycle. Both stages of photosynthesis take place in chloroplasts. The light reactions take place in the thylakoid membranes, and the Calvin cycle takes place in the stroma.

What are the two main stages of photosynthesis quizlet?

The two stages of photosynthesis are light reactions and the Calvin Cycle. Light reactions occur within the thylakoids and the Calvin Cycle takes place in the stroma. The light reactions create ATP and NADPH, which are used by the Calvin Cycle which also brings in carbon to produce sugar.

Why does photosynthesis have two stages?

The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

What is the first stage of photosynthesis called?

Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the hydrogen carrier NADPH and the energy-storage molecule ATP.

What is the first step photosynthesis?

The first step in photosynthesis is the light reaction or photochemical reactions resulting in the formation of ATP and NADPH, which are later utilised in the biosynthesis process. In the first stage, light energy is captured and converted to chemical energy. Oxygen is produced by splitting of water.

What are the stages of photosynthesis quizlet?

Terms in this set (3)
  • stage one. sunlight absorbed by pigments. light dependent. water is split. …
  • stage two. light dependent. ATP created… used to fuel third stage. …
  • stage three. dark reaction (light independent) also known as the “calvin cycle” glucose created (a product of photosynthesis)

What is Stage 2 of photosynthesis called?

Carbon atoms end up in you, and in other life forms, thanks to the second stage of photosynthesis, known as the Calvin cycle (or the light-independent reactions).

What are the 3 stages of photosynthesis?

The stages of photosynthesis
Stage Location Events
Light-dependent reactions Thylakoid membrane Light energy is captured by chloroplasts and stored as ATP
Calvin cycle Stroma ATP is used to create sugars that the plant will use to grow and live

What happens in the second step of photosynthesis?

In the second stage, the Calvin cycle takes place. Here, carbon dioxide is used to produce glucose. It is a continuously occurring cycle, hence the name. In addition to the carbon dioxide, the energy that is provisionally accumulated in the ATP and NADPH is also used to generate glucose – the sugar.

What is the first step of photosynthesis quizlet?

The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP.

Where does the 2nd step of photosynthesis occur?

The second stage of photosynthesis is called the Calvin cycle. Photosynthesis takes place in two stages – the first phase is where the light reactions or the light-dependant reactions occur. In the second stage, the light-independent reaction takes place, the Calvin cycle.

Where does the first stage of photosynthesis occur?

The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast. Chlorophyll appears green to the eye because it does not absorb green waves on the light spectrum.

What is photosynthesis process Class 10?

Photosynthesis is the conversion of sunlight, carbon dioxide (CO2), and water into food (sugars) and oxygen by plants, algae, and some microorganisms. Light energy is collected and used by green plants during the process to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.

What is the first stage of photosynthesis?

the light reaction
The first step in photosynthesis is the light reaction or photochemical reactions resulting in the formation of ATP and NADPH, which are later utilised in the biosynthesis process.

The stages of photosynthesis

Calvin cycle Stroma ATP is used to create sugars that the plant will use to grow and live

What is class 3 photosynthesis?

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.

What is photosynthesis 7th class?

Photosynthesis is the process in which solar energy is trapped by chlorophyll to convert the carbon dioxide and water to produce food in the form of glucose. It is produced in the plants where chlorophyll is present inside the chloroplast as trapping the solar energy initiates the process.

What is called 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.
