Question

Write about three steps of photosynthesis and its chemical equation

Answer 1

In photosynthesis
1. There is absorption of light energy from the sun through the the green pigment in plants called chlorophyll. Then

2. The plants leaves which consists of stomata absorb the carbon dioxide from the atmosphere.

3. And finally, roots absorb water along with minerals from the soil and with the help of xylem vessels transport it to aerial parts of the plant. Then there is a chemical reaction in which light energy is changed into chemical energy. And there is also formation of glucose which provide energy to all parts of the plant

The formula for photosynthesis is 6CO2 + 6H2O -> C6H12O6 + 6O2

Answer 2

During photosynthesis, three different sets of events occur.

The following are the steps involved in the photosynthesis process:

1. The first event occurs when light energy in the form of sunlight is absorbed by chlorophyll.

2. The second step in the photosynthetic process is the processing of light energy into chemical energy, which requires the dissociation of water molecules. Hydrogen and oxygen are isolated from the water molecule.

3. The conversion of carbon dioxide into carbohydrates is the third and last step in the photosynthetic process.

Stomata extract carbon dioxide from the atmosphere, while waste product elimination refers to the release of oxygen. Stomata play a crucial function in the photosynthesis process. They assist in the gas exchange.

The chemical equation for the photosynthesis process is as follows:

$6CO_{2}+6H_{2}O\to C_{6}H_{12}O_{6}+6O_{2}$

Here,

$CO_{2}=carbon\ dioxide$

$H_{2}O= water$

$C_{6}H_{12}O_{6}=glucose$

$O_{2}=oxygen$
