what substances are required for the process of photosynthesis
Answers
Answer:
Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place.
Explanation:
Photosynthesis is the process by which photosynthetic organisms (Green plants, algae, photosynthetic bacteria) capture light from the sun and is converted into the chemical energy, in the form of carbohydrate (starch)
with the help of atmospheric carbon dioxide and water to carry out vital functions of living things.
The basic substances for photosynthesis are Chlorophyll, Sunlight, Carbon dioxide, and Water.
Chlorophyll: It is a green color pigment, present in the chloroplast of the plant cell. The two components of Chlorophyll a, PSI (photosystem I) and PSII (photosystem II) absorbs sunlight and the captured energy further used to split the water molecules.
Sunlight: Photosynthesis is a light-dependent process; thus, the specific wavelength of sunlight (red and blue) excites the photoreceptor (chlorophyll) to carry out the photo-chemical reaction.
Carbon dioxide: This gas is abundantly present in the atmosphere. Plants absorb carbon dioxide through the small openings present on the leaf surface, known as stomata.
Water: Plants absorb required water from the ground through their roots, and water transported to the leaves via stem through a complex transport tissue, the xylem.
Answer:
CO2 and water by using sunlight energy in the presents of chlorophyll, is called photosynthesis.
