What is photosynthesis ?What things are used in photosynthesis?Why plant do it?​

Answer 1

Explanation:

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

Answer 2

Answer:

What is photosynthesis ?

Photosynthesis is a process of manufacture of organic compounds within chlorophyll containing cells from carbon dioxide and water in the presence of sunlight (acts as a source of energy).

The overall process of photosynthesis can be represented by the following equation:

$6C0_{2} +12H_{2}O\frac{Chlorophyll, Enzymes}{Sunlight}> C_{6}H_{12}O_{6}+6H_{2}O+6O_{2}$

What things are used in photosynthesis?

1. Carbon Dioxide -:

In terrestrial plants, carbon dioxide is acquired from the atmosphere through the stomata.

2. Water -:

The main purpose of water is to provide hydrogen for the synthesis of organic compounds.

3. Sunlight -:

It acts as a source of energy.

The use of sunlight by plants doing photosynthesis is the basis of life on earth.

Why plants do it?

Plants being autotrophs, have to prepare/synthesize the food they need through photosynthesis since it's the only means by which organisms can produce their own organic food from inorganic raw materials with the help of sunlight/solar energy.

Hope it helps!
