Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the descriptions below best describes photosynthesis?
A
C6H12O6 + O2
B
an ATP-making process that occurs in the mitochondria
C
sunlight energy is stored in carbon-based molecules like glucose
D
chemical energy is released when glucose is broken down into carbon dioxide.
Explanation: 

Detailed explanation-1: -Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.

Detailed explanation-2: -The correct answer is D. The energy from the sun enters the ecosystem when green plants, green algae, and phytoplankton conduct photosynthesis. Photosynthesis is a process that uses light energy in order to convert carbon dioxide and water into glucose and oxygen.

Detailed explanation-3: -Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.

Detailed explanation-4: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose.
