MCQs

Explanation
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  fo r   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 ND2-03-2023 ** ND22-1-2023

Explanation
The greenhouse effect refers to the way certain gases in the Earth's atmosphere. Such as carbon dioxide, methane, and water vapor , trap heat from the sun, keeping the planet warm enough to support life.

Explanation
Thermochemistry is the study of chemical reactions and the energy changes that involve heat. *** RY24012023

Explanation
The burning of substances in air or oxygen on heating, with the release of a large amount of heat energy and light energy, is called combustion while In conduction , heat transfer occurs between objects by direct contact. In convection , the heat transfer takes within the fluid Condensation is the process by which water vapor in the air is changed into liquid water; it's the opposite of evaporation ** ND22-1-2023 *** RY24012023

Explanation
Convex lenses are also known as converging lenses since the rays converge after falling on the convex lens. The concave lens are known as diverging lenses, as the rays diverge after falling on the concave lens. *** RY24012023

Explanation
Retina : The retina is the light-sensitive tissue at the back of the eye. The retina converts light into electrical impulses that are sent to the brain through the optic nerve. Vitreous gel : The vitreous gel is a transparent, colorless mass that fills the rear two-thirds of the eyeball, between the lens and the retina. *** RY24012023

Explanation
When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material ; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. *** RY24012023

Explanation
When Galileo pointed his telescope at Jupiter, the largest planet in our solar system , he made a startling discovery. The planet had four "stars" surrounding it. *** RY24012023

Explanation
When water cools from 4°C to 0°C , ice crystals begin to form  When water freezes , the water molecules form a lattice that increases the volume. As a result, the density decreases ** ND22-1-2023

Explanation
Inclined planes are used to move heavy loads over vertical obstacles. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.  ND20-1-2023
