Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.
Condition B. concentration of carbon dioxide in the leaf must be less than the concentration of carbon dioxide in the air must be true for carbon dioxide to move from the outside air into the leaf through the stomata.
<h3>What are the stomata plants?</h3>
The stomata plants are structures in the leaves which allow them to produce the exchange of gases (i.e. carbon dioxide and oxygen) which are required and or produced during photosynthesis.
Therefore, with this data, we can see that the stomata plants are used by plants to exchange carbon dioxide with the surrounding environment.
Complete question:
For carbon dioxide (CO2) to move from the outside air into the leaf through the stomata, the following condition must be true:
A. concentration of CO2 in air must be less that the concentration of CO2 in the leaf
B. concentration of CO2 in leaf must be less that the concentration of CO2 in the air
C. concentrations in the air and leaf must be equal
D. none of the above
