2. Why do plants have different colours and smells?

Color comes from a flower's hereditary genome. These genomes determine what pigments a flower will have, and pigments yield different colors.

Plants have different colours and smells because they come in different varieties.

Explanation:

Different plants must lure particular types of pollinators, for instance, and thus they must have specific combinations of scent and colour. Floral fragrance and pigment can also be hereditary, and the most favorable traits likely become the most common in any given plant variety over time.

read the excerpt from "the tell-tale heart.”

object there was none. passion there was none. i loved the old man. he had never wronged me. he had never given me insult. for his gold i had no desire. i think it was his eye! yes, it was this! he had the eye of a vulture—a pale blue eye, with a film over it. whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—i made up my mind to take the life of the old man, and thus rid myself of the eye forever.  

read the excerpt from "the black cat.”

beneath the pressure of torments such as these, the feeble remnant of the good within me succumbed. evil thoughts became my sole intimates—the darkest and most evil of thoughts. the moodiness of my usual temper increased to hatred of all things and of all mankind; while, from the sudden, frequent, and ungovernable outbursts of a fury to which i now blindly abandoned myself, my uncomplaining wife, alas! was the most usual and the most patient of sufferers.
