Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these is the source of the energy that plant cells use for photosynthesis?
A
radiant energy from the sun
B
kinetic energy from the wind
C
potential energy from the soil
D
mechanical energy from animals
Explanation: 

Detailed explanation-1: -Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and reflects green light.

Detailed explanation-2: -During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

Detailed explanation-3: -Photosynthesis is the process through which plants convert sunlight, water, and carbon dioxide into oxygen and sugar energy. The term “photosynthesis” thus refers to synthesis from light. So it is clear that the energy for photosynthesis comes from light.

Detailed explanation-4: -Photosynthesis is the process in which plants collect radiant energy (from the Sun) and transform it into chemical energy. The chemical energy is stored in the plant as sugar and is available as food. The leaves of plants contain everything needed to absorb the rays of the Sun and start photosynthesis.
