PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes a process of photosynthesis? Photosynthesis is the process by which plants convert-
A
radiant energy into chemical energy.
B
heat energy into mechanical energy.
C
heat energy and chemical energy.
D
chemical energy into heat energy.
Explanation: 

Detailed explanation-1: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-2: -Photosynthesis is the process that plants use in the presence of sunlight to convert carbon dioxide taken in by their leaves and water taken in through the roots to produce oxygen and sugar (glucose). This process takes place in the chloroplast of the plant cell with the presence of the green pigment of chlorophyll.

Detailed explanation-3: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-4: -Photosynthesis is the process of utilizing and converting light or solar energy into chemical energy. Sunlight is absorbed by chlorophyll of leaves. Here, light energy is converted into chemical energy and is stored as ATP molecules. This energy is used by plants for the life processes.

Detailed explanation-5: -Photosynthesis is the process used by plants, algae and some bacteria to turn sunlight into energy. The process chemically converts carbon dioxide (CO2) and water into food (sugars) and oxygen. The chemical reaction often relies on a pigment called chlorophyll, which gives plants their green color.
