What is the purpose of photosynthesis and what are the 2 steps?

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

What are the first and second steps of photosynthesis?

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.

What are the two stages of photosynthesis Brainly?

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

What are the 3 steps of photosynthesis?

1 Answer

  • Absorption of light energy by chlorophyll.
  • Conversion of light energy to chemical energy and splitting of water molecule into hydrogen and oxygen.
  • Reduction of carbon dioxide to carbohydrates. Please log in or register to add a comment. ← Prev Question Next Question →

What are the steps of photosynthesis quizlet?

Terms in this set (7)

  • Step 1-Light Dependent. CO2 and H2O enter the leaf.
  • Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
  • Step 3- Light Dependent. The electrons move down to enzymes.
  • Step 4-Light Dependent.
  • Step 5-Light independent.
  • Step 6-Light independent.
  • calvin cycle.

What are the three steps of photosynthesis?

1- Absorbing light energy by leaves. 2- Conversion of light energy into chemical energy. 3- Reduction of carbon dioxide into carbohydrates.

What are the two stages in 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 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.
