All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

Oxygen is necessary for combustion.

Explanation

This is called nuclear fusion.

It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy

Explanation

Natural Gas is also known as Methane.

The principal use of methane is as a fuel.

Natural gas is a fossil fuel energy source.
