Question

what is photosynthesis?

Answer 1

Answer:

• Photosynthesis is the chemical process in which ‘green plants’ that use the energy of the sunlight to convert “water and carbon-dioxide” into ‘high energy carbohydrates and oxygen’.

• Plants need respiration, growing and reproducing food. Unlike livestock, the method of photosynthesis allows crops to ‘produce their own food’.
• ‘Photosynthesis’ occurs in the chloroplast portion of the plant body, these are tiny chlorophyll-containing structures.

The chemical reaction of photosynthesis is followed as:

$\text {Carbondioxide}+\text { Water } \stackrel{\text { Sunlight }}{\longrightarrow} \text { Glucose }+\text { oxygen }$

Answer 2

• Photosynthesis is the conversion of light energy into chemical energy in green plants and other organisms.
• Light energy is collected and utilized by green plants to transform water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules during photosynthesis.

Photosynthesis is expressed as

• 6CO2 + 6H2O C6H12O6 + 6O2.

• This signifies that the reactants, six carbon dioxide molecules and six water molecules, are transformed into a sugar molecule and six oxygen molecules.
• The products, by light energy collected by chlorophyll (implied by the arrow).
