im kept two identical green plants in his garden and labeled them A and B. He watered plant A every day and plant B once a month. After a month, the leaves of plant A remained green but the leaves of plant B turned yellow.

Question

Which statement best explains this difference in color?

Plant A got sufficient water to produce hydrogen.
Plant A got sufficient water to produce carbon dioxide.
Plant B did not get sufficient water to convert carbon dioxide into hydrogen.
Plant B did not get sufficient water to convert carbon dioxide into glucose.

Answer 1

The statement that best explains the difference in color between the two plants is:

Plant B did not get sufficient water to convert carbon dioxide into glucose.

This is because plants require water for the process of photosynthesis, which allows them to convert carbon dioxide and sunlight into glucose (a form of energy) and oxygen. Without adequate water, plant B was unable to perform photosynthesis efficiently, leading to its leaves turning yellow. In contrast, plant A received sufficient water, enabling it to remain healthy and green.
