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.
Plants contain other pigments that reflect different colors, but these are often masked by Chlorophyll. An example of another common pigment is the carotenoids. During autumn, when the days begin to shorten, the amount of chlorophyll in the leaves of trees is dramatically reduced.
All species of plants are different from one another. Some, like trees and wildflowers, are very familiar to us. Some, like mosses or hornworts, are much more mysterious. Even though there are such a variety of plants, there are a few things that all plants have in common.At the cellular level, all plants are eukaryotic-meaning they have a nucleus and other organelles. One type of organelle in particular-chloroplasts-are found in all plants.his is very important because plants are the only types of organisms that can do this. All other types of living things either need to eat plants or eat things that eat plants in order to get their energy. Plants are at the base of every type of food web. Without plants, there would never be any kind of food.
