Plant blindness refers to "the inability to see or notice the plants in one's own environment." The term plant blindness was coined twenty years ago by Elizabeth Schussler and James Wandersee who are botanists. Plant blindness results in "the inability to recognize the importance of plants in the biosphere and in human affairs." It is also the reason why people have a tendency of ranking “plants as inferior to animals”. Therefore, plants tend to receive limited care and upkeep. It is important to recognize plant blindness so that more intentional care can be given to preserving our plant species and ensure their survival and ability to thrive.

C. This is the main way resistance is controlled. The smooth muscle surrounding blood vessels can rapidly respond to hormonal or metabolic stimuli and contract/relax to adjust diameter.
D. Again, temperature is fairly constant in the body and would not be a good way to alter resistance.
