Martin grew some bean plants. He made a list of what the bean plants needed to survive and grow. Which gas do this plants need when they make their won food?
A
oxygen
B
nitrogen
C
hydrogen
D
carbon dioxide
Explanation: 

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy. The relationship between air and indoor plants is crucial to keeping your plants looking their best.

Detailed explanation-3: -The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air. Take a look at the picture below to see this system in action. This leftover oxygen is really important because humans and other animals need this oxygen to live which we breathe in from the air.
