Dolly the sheep, the first mammal cloned from a somatic (body) cell, came into the world innocent as a lamb. However, soon after the announcement of her birth in February 1997 (Wilmut et al., 1997) she caused panic and controversy. An important, and for many people troubling question arose: if the cloning of sheep is possible, will scientists soon start cloning humans as well; and if they did, would this be wrong or unwise? For most people, Dolly was really a wolf in sheepâs clothing.
According to the University of Vermont Extension, the reasons plants have different colors is because of pigments within the plant. A variety of pigments are held within different plants, other factors regarding plant color include the amount of sugar and light a plant receives.
Chlorophyll just absorbs blue and red light; it hardly absorbs any green light at all, so the green gets reflected back to our eyes, which is why leaves appear green. Other pigments that plants have in their leaves absorb light of different colors, so they reflect red, orange, yellow, or blue light and appear to be those colors to our eyes. Because the white light coming from the sun is actually made up of photons of all the different colors, it is very advantageous to the plant to have many pigments that can absorb such a wide range of the available colors of light.
