The answer is B. The number of stomata is more on the lower surface of the leaf. The primary function of the stomata is to regulate moisture loss from the plant. The upper surface of the leaf is more exposed to the air and sunshine thus water is more susceptible to evaporation. However, the stomata is abundant on the lower surface, the location of it helps the plants to conserve more water 
        
             
        
        
        
In general cells that need more energy, since mithocondria are responsible for making and processing ATP.
Common examples of cells with many mithocondria are muscle cells that are in current activity all the time, specially heart muscles and muslces in the respiratory system such as the diafragma since the heart beats all the time, non-stop, that is, unless you die of course and so do the muslces needed to breath.

The Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.
<h3>What is an organism?</h3>
An organism is a living entity that is defined by the presence of cells, which are the basic structural unit of life.
Organisms have the ability to respond to external stimuli, perform metabolic activities and exhibit a internal state of equilibrium (homeostasis).
Organisms can be composed of single cells (e.g., bacteria, protists) or many cells (e.g., plants and animals).
In conclusion, the Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.
