Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis?
A
The light-dependent stage
B
The light-independent stage (The Calvin Cycle)
C
The electron transport chain
D
ATP formation
Explanation: 

Detailed explanation-1: -C3 photosynthesis is used by the majority of plants. It involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become glucose.

Detailed explanation-2: -During photosynthesis carbon dioxide (CO2) is utilized during the Calvin cycle, also known as the dark reactions.

Detailed explanation-3: -The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Every living thing on Earth depends on the Calvin cycle. Plants depend on the Calvin cycle for energy and food.

Detailed explanation-4: -The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions.
