Thanks :P​

Answer 1

☆ Photosynthesis

It is process which takes place generally in green plants of synthesis of organic food material using Carbon dioxide , water and in the presence of sunlight inside the cell which contains chlorophyll.

Requirements of Photosynthesis are :-

1. Chlorophyll

2. Carbon dioxide

3. Water

4. Sunlight

And some other raw materials which are required such as Nitrogen, phosphorus, Iron and Magnesium.

Here Nitrogen and sulphur are essential elements used in synthesis of proteins and other compounds.

☆ Functions during photosynthesis :-

The water absorbed by roots from the soil and transported to leaves through stem.

The carbohydrate which are not used by plants then it converted into the form of starch and it is stored in the leaves.

The process of Photosynthesis formula :-

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

Answer 2

ANSWER:-

Photosynthesis is a process by which the plants convert carbon dioxide into organic compounds by using the energy derived from sunlight.The process is also reffered to as carbon fixation process, owing to the fact that the process produces some carbon compounds which store chemical energy meant to be used in cell growth.

⚫Water

⚫Light

⚫Chlorophyll

⚫Carbon dioxide

are the basic requirements for the photosynthesis process.

Photosynthesis process following steps:

Photosynthesis is a process by which photoautotrophs convert unusable sunlight energy into usable chemical energy.

1. Carbon dioxide in the atmosphere enters the plant leaf through the stomata. The stomata are minute epidermal pores in the leaves and stem of the plants which facilitate the transfer of various gases and water vapor through them.
2. This is followed by water entering the leaves, primarily through the roots. The roots are designed to draw in the ground water, and transport it to the leaves through the stem.
3. As sunlight falls on the surface of the leaves, the chlorophyll present in the leaves traps the energy in it. Chlorophyll is a green pigment present in the plant leaf,which helps the plant in absorbing sunlight. The green color of the leaf is also attributed to presence of chlorophyll in it.
4. Then hydrogen & oxygen are produced,as the products of photosynthesis, by converting water using the energy derived from the sun. The hydrogen is combined with carbon dioxide in order to make food for the plant,while oxygen is let out by the plant through the stomata.
5. The electrons from the chlorophyll molecules and the protons from the water molecules facilitate chemical reaction in the cell.These reaction produce ATP(Adenosine triphosphate), provides energy for cellular reactions, and NADP(nicotinamide adenine dinucleotide diphosphate), essential in plants metabolism.

The whole photosynthesis process can be explained by a single chemical formula:

$6CO2 + 12H2O + light ----> C6H12O6 + 6O2 + 6H2O$

While we take in oxygen and give out CO2 to produce energy, plants take in carbon dioxide and give out oxygen to create energy.

Hope it helps ☺️
