Question

CREATIVE
The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons. Cyanobacteria appeared later; the excess oxygen they produced contributed directly to the oxygenation of the Earth, which rendered the evolution of complex life possible. Today, the average rate of energy capture by photosynthesis globally is approximately 130 terawatts, which is about eight times the current power consumption of human civilization. Photosynthetic organisms also convert around 100–115 billion tons (91-104 petagrams) of carbon into biomass per year.
Carry out a research on various factors affecting photosynthesis and link it to the increase in food grain production which is the need of the hour as the world stares at acute food shortage due to coronavirus pandemic.
You can present your research in the form of an article/ presentation/video and support it with illustrations like graphs, pie charts etc.

Answer 1

The various factors affecting the rate of photosynthesis are discussed below:

Explanation:

• Light: As the process of photosynthesis requires light, hence light plays an essential role in increasing the rate of photosynthesis. The more the sunlight, more will be photosynthesis.

• Water is one of the main reactant of photosynthesis. Hence, the presence of ample amount of water is another factor for the rate of photosynthesis.

• Carbon dioxide is also another main reactant of photosynthesis. Hence, the rate of photosynthesis increases with the rate of carbon dioxide.

Answer 2

Answer:

The various factors affecting the rate of photosynthesis are discussed below:

Explanation:

Light: As the process of photosynthesis requires light, hence light plays an essential role in increasing the rate of photosynthesis. The more the sunlight, more will be photosynthesis.

Water is one of the main reactant of photosynthesis. Hence, the presence of ample amount of water is another factor for the rate of photosynthesis.

Carbon dioxide is also another main reactant of photosynthesis. Hence, the rate of photosynthesis increases with the rate of carbon dioxide.
