Introduction:
Green plants are autotrophs which means they can produce their food using inorganic substances and light energy. The raw materials required for photosynthesis are carbon dioxide, water, and sunlight. In this answer, we will discuss in detail how green plants obtain these raw materials.

Obtaining Carbon dioxide:
Carbon dioxide is a gas that is present in the atmosphere. The process of obtaining carbon dioxide by green plants is known as diffusion. The following are the ways in which green plants obtain carbon dioxide:
- Carbon dioxide enters the leaves of the plant through tiny pores called stomata.
- The concentration of carbon dioxide in the atmosphere is higher than that inside the plant, so it diffuses into the plant through these pores.
- The plant can then use the carbon dioxide for the process of photosynthesis.

Obtaining Water:
Water is essential for the process of photosynthesis. The following are the ways in which green plants obtain water:
- Water is absorbed by the roots of the plant from the soil.
- The water is transported to the leaves of the plant through the stem.
- The water is then used in the process of photosynthesis.

Obtaining Sunlight:
Sunlight is the source of energy required for the process of photosynthesis. The following are the ways in which green plants obtain sunlight:
- Sunlight is absorbed by the leaves of the plant.
- The chlorophyll pigments present in the leaves trap the sunlight energy.
- This energy is then used in the process of photosynthesis.

Conclusion:
In conclusion, green plants obtain the raw materials necessary for photosynthesis through the process of diffusion, absorption, and absorption. Carbon dioxide is obtained through stomata, water is absorbed by the roots from the soil, and sunlight is absorbed by the leaves. These raw materials are then used in the process of photosynthesis to produce glucose and oxygen.

Green plants take sunlight with the help of chlorophyll. it takes water and minerals from roots with the help of phloem. they take co2 from air with help of stomata. thanks and very nice question.
