Where is the first step of photosynthesis?
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.
What is photosynthesis step by step?
Process of Photosynthesis Step by Step The sunlight is absorbed by the chlorophyll in the leaves of the plants. Carbon dioxide enters the plant through structures called the stomata, which are usually found on the underside of the leaves. Water is absorbed through the roots of the plant.
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.
What are the 5 steps of photosynthesis in order?
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 3 steps of photosynthesis?
Photosynthesis in plants is of 3 steps, occurring in chloroplast:
- Absorption of light,
- Conversion of light energy into chemical energy and splitting of water molecules,
- Carbon dioxide is reduced to carbohydrates.
What is the first stage of photosynthesis in a chloroplast?
Stage I is called the light reactions. This stage uses water and changes light energy from the sun into chemical energy stored in ATP and NADPH (another energy-carrying molecule).

What is the 2nd stage of photosynthesis?
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 |
