Choose a plant organ. Write an explanation of
how that organ's structure relates to its function.
Be specific and detailed.

Leave is an important structure of plant body where food production occurs in the process of photosynthesis. In the leaves, small tiny pores called stomata are present on lower side of the leaf. These pores are responsible for the exchange of gases such as carbondioxide and oxygen. These stomata opens and carbondioxide is absorbed from the atmosphere and water from the soil. Both reactants combine in the presence of sunlight producing oxygen and glucose. Oxygen is released through stomata and glucose is stored in different parts of plant.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
