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.
What pigment gives plants their green color? The green pigment chlorophyll is responsible for the colour of plants. The pigment is found in organelles called chloroplasts which are found in most plant cells (particularâ¦ly in the leaves and stems). The pigment is green in colour and reflects green light, giving the plants their green colour.
