Question

what is photosynthesis?







please follw me​

Answer 1

Answer:

the process by which green plants turn carbon dioxide and water into food using energy from sunlight

HEYA, BUDDY !!

:$\implies$The word photosynthesis comes from two Greek words, fos (light), and synthesis (combining). The photosynthesis definition says that it is a combination of plant food's creation with the help of light.

→ The Photosynthesis reaction occurs in green plants, and in some prokaryotes, purple bacteria, and green sulfur bacteria. The photosynthesis process in all of them is similar.

★ Process

→ In plants and blue-green algae, the photosynthesis process takes place in chloroplasts. The chloroplast is present in all green parts of a plant – the leaves, green stems, sepals, and even in the flowers, in the form of green colour plastids. The chloroplast is found only in plant cells and is essential for photosynthesis reaction.

★ Factors Affecting Photosynthesis

→ Light Intensity: More the light, the more will be the rate of photosynthesis. Similarly, low light will lead to a low rate of photosynthesis.

The Concentration of CO2: A higher CO2 concentration rate in a plant also accelerates the photosynthesis process. The required amount of CO2 is 300-400 PPM.

Temperature: If the temperature is between the range of 25 to 35 degrees Celsius, the photosynthesis takes place effectively.

Water: An essential amount of water is required for stomatal opening, and it’s a key factor in the process of photosynthesis.

Pollution: The increasing rate of polluting particles in the atmosphere block the pores of somatic cells, and the intake of carbon dioxide becomes difficult.

→ The Carbon dioxide and water are the two major factors involved in the photosynthesis reaction. It’s an endothermic reaction, and the products resulting from it are oxygen and glucose. The formula is:

→ 6CO2 + 6H2O = C6H12O6 + 6O2

→ However, some bacteria don’t produce oxygen as a by-product of photosynthesis. They are called anoxygenic photosynthetic bacteria, and those who do it are called oxygenic photosynthetic bacteria.
